Entrepreneurship

Overview

Product purpose

The project, initiated by the NSFLS-CHINA team, aims to revolutionize the production of natural astaxanthin through synthetic biology techniques. We used directed evolution techniques to rationally design the key enzyme (β -carotene hydroxylase) to obtain high-performance engineered strains and relied on a mature E.coli fermentation platform to efficiently produce high-purity, high-bioactive natural configuration (3S,3'S) astaxanthin through engineered E.coli, and we have filed a Chinese invention patent application (application number: CN202511043781.7) and a PCT international patent application (application number: PCT/CN2025/124139) to protect our technology worldwide. Compared with traditional extraction and chemical synthesis methods, our technology has competitive advantages of low cost (reduced by 50-70%), high purity (>95%), strong sustainability and good product consistency, achieving efficient, green and low-cost production of astaxanthin. Our products are mainly targeted at the cosmetic raw materials market (B2B) and the terminal anti-aging and sensitive skin care products market (B2C). In terms of business model, we adopt a "B2B first, then B2C" approach, initially entering the market as a supplier of high-end raw materials, serving the cosmetics and health care products industry; The long-term goal is to build our own brand and launch our own brand of skincare products (B2C) for end consumers when the funds and channels are mature.

In addition, the simplification of the "Cosmetic New Ingredient Filing Regulations" will keep the annual growth rate of new ingredient filings containing astaxanthin above 50%, which will drive the further expansion of astaxanthin's application and market size in the cosmetics sector. Figure 2. Global and Chinese Astaxanthin market size from 2020 to 2025 (Unit: 100 million yuan)

Export potential

China has become the world's largest exporter of astaxanthin, with exports reaching $347 million in 2024, mainly to the United States, Japan and the European Union, with the U.S. market accounting for 41.2%. With the increasing awareness and demand for astaxanthin in the international market, there is huge export potential for astaxanthin cosmetics from China.

Potential customers

NSFLS-China has gained a certain understanding of the needs of potential customers through interaction with stakeholders.During the interview with BiSheng Biotechnology Company, we learned about the activities required for the commercialization of the product. Considering the needs of the actors that we had previously understood, we decided to utilize the properties of astaxanthin red and antioxidant to create a non-toxic and harmless cosmetic. During the interview, Dingjian Testing helped us access the materials that need to be submitted for the product's launch, the laws and regulations that need to be followed, the preservation issues during transportation of the product, as well as the precautions in terms of promotion, such as packaging and advertising. We distinguish potential customers from other stakeholders, dividing them into target groups with the intention to purchase and use our products, as well as groups and individuals interested in our products. We roughly divide potential customers into the following two categories:

We can provide brands with stable, high-quality, cost-advantaged natural astaxanthin ingredients for developing pre-makeup essences, primer products, pore care products, etc., to enhance product competitiveness.

Unmet needs not yet covered by existing alternative solutions

Production technology bottlenecks

Table 1. Three core pain points and significant market gaps in existing astaxanthin production and application solutions.

Product application pain points

Stability & solubility

Poor stability: astaxanthin is prone to oxidation under light and high temperatures, traditional oil-based products have a shelf life of only one year and need to be used up within one month after opening, with a consumer complaint rate of 18% (Tmall after-sales data);

Poor water solubility: Astaxanthin is insoluble in water and can only be used in oil-based products (such as essence oil), not compatible with water-based products (such as toner, mask liquid), limited application scenarios, missing out on 35% of the water-based skincare market.

Bioavailability & efficacy

Low bioavailability: The human absorption rate of common oil astaxanthin is only 15% (PubMed study data), and high doses are required to be effective, increasing consumer costs;

Exaggerated efficacy claims: 38% of astaxanthin skin care products have exaggerated claims such as "anti-aging in 7 days" and "reducing wrinkles by 50%" (NMPA 2024 sampling report), and the actual efficacy is not supported by clinical data, leading to a decline in consumer trust.

Safety & adaptability

Safety risks: 12% of astaxanthin skin care products detected heavy metals (such as lead, mercury) or hormones (such as dexamethasone) (NMPA sampling), long-term use can lead to skin dependence, hormone-induced face;

Poor individual fit: The proportion of sensitive skin in Asians (38%) is higher than that in Europeans and Americans (25%), but existing imported products are mostly designed for European and American skin types, with a pH value that is slightly alkaline (7.5-8.0) and does not match the pH value of Asian skin (5.5-6.5), with an irritation rate of 22%.

Feasible & scalable & innovative

Possible

Technical possibility

Currently, the production of astaxanthin (algal extraction, chemical synthesis) faces bottlenecks of low yield and insufficient product activity. Biocatalysis using highly specific carotenoid hydroxylase (which has been proven to be compatible with E. coli β-carotene) is a highly promising alternative method. The Machine Learning combined with directed evolution technology we studied can efficiently engineer this enzyme, improve its catalytic efficiency, enhance its tolerance in the host, and directly target the metabolic bottlenecks of traditional methods such as chemical synthesis and natural extraction. Our key advantage lies in the fact that the engineered E.coli system can significantly reduce production costs by over 50% compared to traditional methods, and can efficiently produce natural active astaxanthin, demonstrating significant technological and industrialization potential.

Economic possibilities

The production of astaxanthin using engineered E.coli demonstrates remarkable economic potential, with its core advantage being a reduction of approximately 50-70% in comprehensive production costs. This is attributed to multiple efficiency improvements: first, a significant reduction in the fermentation cycle, which lowers the allocation of fixed costs and energy consumption; second, the efficient utilization of the substrate β-carotene, reducing raw material consumption; finally, the simplification of the purification process, saving separation media and labor hours; after querying the study on the production of glycolic acid from low-cost biomass by E.coli fermentation and its separation and purification, we learned from and relied on the mature, stable, and easily scalable fermentation process platform of E.coli, reducing the risk of technology transfer and the threshold for scale-up[3].

In addition, the astaxanthin produced by engineered bacteria has extremely high purity (up to over 95%), and its biological activity and storage stability are superior to those of the natural extraction method. Due to the different sources of naturally extracted astaxanthin, its molecular configuration also varies. E.coli can directionally synthesize astaxanthin with the left-handed (3S, 3'S) configuration through gene editing technology, which is also the most common and highest antioxidant activity configuration in nature. The astaxanthin synthesized by Haematococcus pluvialis has a left-handed (3S-3'S) structure, which is basically the same as the astaxanthin configuration in aquaculture organisms such as salmon, and has extremely strong biological activity. By producing astaxanthin through E.coli, it is possible to precisely synthesize astaxanthin with a specific configuration and high biological activity by means of gene editing and other methods, simulating the synthesis of left-handed astaxanthin by Haematococcus pluvialis, thereby enhancing its biological activity. This not only increases the product value, reduces storage and transportation losses, but also facilitates entry into high-profit markets such as cosmetics, further enhancing its economic attractiveness.

The current challenge lies in the fact that high-density fermentation and product synthesis have strict requirements for environmental control (temperature, induction conditions), which increases the complexity of process control and initial investment, and limits immediate large-scale production. However, its disruptive cost reduction ability, excellent product quality, and mature chassis system have laid a solid foundation for the industrial economic feasibility of its large-scale application, with a clear prospect.

Community possibilities

Currently, through social practice and interviews, it can be understood that in today's society, the female population and even some male individuals pay high attention to skin anti-aging issues, and they generally have a need to have young and healthy skin. As people reach middle age, their skin often faces problems such as dryness, lack of moisture, loss of luster, and loss of elasticity, and astaxanthin can precisely provide practical and effective solutions to these problems. Relevant research Cosmetic benefits of astaxanthin on humans subjects - PubMed[4] has confirmed that astaxanthin has the ability to penetrate deep into the skin, not only repairing the damaged skin tissue structure but also strengthening the skin's natural protective barrier, and further playing a role on this basis: helping to reduce the depth of wrinkles, fade skin pigmentation, and ultimately improve the overall health of the skin and restore its plump and firm texture. It is worth noting that the astaxanthin we promote is prepared using enzyme engineering E.coli production technology, which demonstrates excellent economic potential - the comprehensive production cost is reduced by approximately 50-70% compared to traditional methods. On the one hand, it reduces the fixed cost allocation and energy consumption by significantly shortening the fermentation cycle, efficiently utilizes the substrate β-carotene to reduce raw material consumption, and simplifies the purification process to save separation media and man-hours; On the other hand, by leveraging the mature, stable, and easily scalable fermentation process platform of E.coli, it reduces the risks of technology transfer and the threshold for scale-up. Meanwhile, it can directionally synthesize left-handed (3S, 3'S) configuration astaxanthin (purity can reach over 95%), which is the most common and has the highest antioxidant activity in nature, consistent with the active configuration of astaxanthin in Haematococcus pluvialis and aquaculture organisms such as salmon. Its biological activity and storage stability are both superior to those of natural extraction methods, better ensuring anti-aging effects and reducing product storage and transportation losses. From the perspective of demand, women of all age groups in the community have a certain demand for anti-aging. The NSFLS-CHINA team plans to conduct promotional activities in nearby communities and distribute trial packs of anti-aging masks containing the above-mentioned highly active astaxanthin. If the product receives favorable feedback during small-scale community trials, it can not only achieve word-of-mouth promotion within the community, but also leverage its cost advantages on the production side and high activity advantages on the product side to facilitate further promotion of the product within the community, laying the foundation for its subsequent entry into high-profit markets such as cosmetics.

Scalable

Compared with other astaxanthin products using natural extraction or chemical synthesis, the research results of NSFLS-CHINA have certain advantages in terms of yield and cost. Our astaxanthin is currently suitable for various applications, including personal use and small-scale production, and will continue to be applicable in the future. In the future, we will consider how to apply astaxanthin to facial masks and contact manufacturers to expand production. With these advantages, we can quickly expand our market coverage.

Innovative

We use E. coli to build cell factories. Our communication with stakeholders indicates that our solutions to urgent needs are safer, more environmentally friendly, and more cost-effective. The NSFLS-CHINA team obtains better protein structures through computer modeling and prediction to enhance activity, and proposes product usage methods not available on the market, such as colored lip masks, skin-care oil paints for Chinese drama facial makeup, and addresses the issues faced by people with oily skin in Europe and America, where anti-aging products like astaxanthin essence oil that nourish the skin with oil are too greasy, difficult to absorb, and may even lead to clogged pores, acne, etc.

We have carefully considered our growth plan. Our business model clearly outlines our development plan, including the resources involved and the key activities. We have also based our development plan on this. Figure 8 . This is the summary diagram of the company's business plan.

Exit strategy

Regarding the exit strategy, NSFLS-CHINA takes Initial Public Offering (IPO) as one of its core exit strategies. We plan to achieve the transformation from a private enterprise to a Listed Company by offering shares to the public. Although this path is highly challenging and has strict requirements for product market influence and branding impression, it also contains great potential for value release. We will promote our business through keynote speeches, technology demonstrations, etc., and enhance product market awareness through diversified channels such as industry summits and media cooperation. At the same time, we will carry out online and offline brand activities to strengthen end users' perception of product value. Through Initial Public Offering (IPO), we can obtain substantial profits upon exit, thereby enhancing the publicity, social Reputation, and branding impression of the company's products, injecting capital impetus into the company's subsequent development, laying a solid foundation for long-term strategic layout, and achieving the organic unity of short-term interests and long-term development.

We can also choose a widely used exit route - merger and acquisition (M&A) exit, which involves having the company acquired by another enterprise with more experience in business operations and a larger scale. This approach can maximize the retention of our autonomy, allowing us to still have a say in product development and pricing strategies: we can either choose to continue in-depth involvement, controlling the price system and the direction of product iteration; or completely divest the business to achieve a full exit. If our core product is successfully approved, we can seek to merge with a well-known large cosmetics group. By leveraging its established distribution network and brand influence, we can not only continue to drive market penetration of our existing product lines, but also rely on the other party's resource advantages to expand the R&D and output of new product categories, creating more room for the continuous release of brand value while achieving a smooth transition. This flexible exit model takes into account the option of controlling the business and also injects new possibilities into enterprise development.

If none of the above strategies prove effective, we can choose equity stake transfer as the final exit strategy. We can relatively flexibly transfer our equity stake in the enterprise to other investors and select a suitable transferee based on the actual situation of the enterprise. However, this option will only be considered when neither of the above two strategies works.

Further development

Each member has their own unique interests and personality, and they excel in a wide range of fields such as natural sciences, social sciences, science and engineering, and liberal arts, ensuring that different knowledge perspectives and ideas can achieve cooperation through collision, paving the way for the harmonious development of the NSFLS-CHINA team. Despite the challenges, the team atmosphere is very friendly and collaborative. In addition, the experimental skills, social practice experience, and excellent research results gained in the vibrant campus enable us to fully engage in the continuous development of the project. With a relatively in-depth understanding of the appearance anxiety and aging issues currently plaguing society, NSFLS-CHINA is firmly moving towards its ultimate goal - deciphering the code of youth, launching more environmentally friendly antioxidant skincare products, enabling the people we love to have better looks, and alleviating social appearance anxiety.

With the help of experienced mentors, the potential of team members has been further tapped, enabling us to gain a deeper understanding of relevant topics and thus turn the team's goals and dreams into reality. Moreover, our achievements are largely attributed to the close connection with Shenzhen University, which provides experimental equipment, allowing us to conduct in-depth research and thrive in well-equipped laboratories, validating our constructive ideas.

We are committed to becoming a pioneer in the field of anti-aging skincare, continuously driving industry innovation through cutting-edge technology. Our research aims to make anti-aging skincare more healthy and sustainable, benefiting humanity and the environment, and ensuring the provision of anti-aging skincare products and cosmetics that combine health benefits with safety guarantees for global consumers. In our in-depth research in the anti-aging field, we always adhere to "health" and "sustainability" as core principles. From the screening of bioactive ingredients to the optimization of formulation systems, every step of exploration is dedicated to reducing the burden on the skin and minimizing the impact of the production process on the ecosystem, striving to contribute to the sustainable development of the planet while maintaining the youthful state of human skin.

This unwavering commitment to innovation will ultimately enable anti-aging skincare products nourished by technology to enter the lives of more people, ensuring that beauty and responsibility always go hand in hand.

Long-term impact

Given the challenges faced by anti-aging products and the limitations of existing astaxanthin production methods, NSDFLS-CHINA is committed to developing safe, environmentally friendly, and cost-effective products using synthetic biology. Based on our analysis, our products will have the following impacts on people's health, society, and even the environment.

Health

Traditional astaxanthin products often have two major health risks: natural extraction is prone to introducing impurities due to raw material contamination (such as heavy metals in sea areas, pesticide residues in algal bodies, etc.), while chemical synthesis may leave behind toxic catalysts (such as heavy metal compounds), and long-term use may lead to problems such as skin sensitivity and metabolic burden. In contrast, NSDFLS-CHINA's astaxanthin achieves "clean synthesis" through synthetic biology technology in an engineered E.coli system - the fermentation process uses food-grade culture medium, has no exogenous pollutants, and can directionally synthesize highly active left-handed (3S-3'S) configuration astaxanthin (which has stronger compatibility with human skin). Verified by a third-party testing agency, the product purity reaches 98.2%, with no risks of heavy metals, pesticide residues, etc.

In terms of health benefits, this product not only meets anti-aging skincare needs (such as reducing fine lines and improving dullness by scavenging free radicals in the skin), but its stable molecular structure can also be better absorbed by the human body, helping to enhance the body's antioxidant capacity (such as reducing skin damage from ultraviolet rays and lowering oxidative stress after exercise), providing an "internal and external synergy" health solution for different groups of people (such as night owls, outdoor workers, and middle-aged and elderly people).

Society

From an industrial perspective, this product has broken the foreign monopoly on high-purity astaxanthin production technology (for example, the traditional high-end astaxanthin market has long been dominated by Japanese and US enterprises, relying on natural algal strain cultivation technology). NSDFLS-CHINA has built an independently controllable fermentation production system through synthetic biotechnology, which not only lowers the production threshold of astaxanthin (compared with traditional natural extraction, equipment investment costs are reduced by 40%), but also drives the development of upstream and downstream industries - upstream, it can stimulate the demand for supporting industries such as food-grade culture media and bioreactors, and downstream, it provides cost-effective raw materials for industries such as cosmetics and health products, helping domestic beauty and health industries transform from "raw material import dependence" to "self-developed technology empowerment" and enhancing the competitiveness of local industries.

From a people's livelihood perspective, this product combines both "universality" and "accessibility": on the one hand, in response to anti-aging skincare needs, its stable characteristics can be adapted to various skincare product formulations such as masks, serums, and lotions. After large-scale production in cooperation with manufacturers in the future, more affordable and high-quality anti-aging products can be launched, allowing ordinary consumers to avoid the cost of high-priced imported products; on the other hand, in remote areas or areas with weak medical resources, as an antioxidant supplement that is easy to store and transport, this product can help improve the health security conditions of local residents and provide grassroots support for the construction of a Healthy China.

Environment

Traditional astaxanthin production models impose a heavy burden on the environment: natural extraction relies on large-scale cultivation of Haematococcus pluvialis, which requires a vast amount of arable land or sea area, and the cultivation process requires precise control of water temperature and light, with extremely high energy consumption (producing 1 kilogram of natural astaxanthin consumes 3,200 kilowatt-hours of electricity); chemical synthesis generates a large amount of acidic wastewater and organic waste gas.

The synthetic biology production model of NSDFLS-CHINA has achieved "triple environmental protection breakthroughs": First, it has low resource consumption. The fermentation process mainly uses renewable raw materials such as glucose and amino acids, without the need to occupy arable land or sea areas. Through metabolic optimization of engineered bacteria, the raw material conversion rate reaches 82% (the raw material conversion rate of traditional natural extraction is only 30%), significantly reducing resource waste. Second, it has low pollution emissions. Fermentation wastewater can be recycled after simple treatment (such as for irrigation and cleaning), without generating toxic and harmful waste. According to environmental assessments, the carbon emission per unit of output is only 1/5 of that of chemical synthesis and 1/3 of that of natural extraction. Third, it has strong risk resistance. It does not rely on the natural environment (for example, natural algal strains are vulnerable to climate change and may experience reduced yields). Indoor fermentation enables stable production, avoiding indirect damage to the ecosystem caused by fluctuations in raw material supply (such as overfishing of shrimp and crabs to obtain shrimp shells and overdevelopment of sea areas for cultivating Haematococcus pluvialis), setting a green benchmark of "low consumption, emission reduction, and sustainability" for the biomanufacturing industry.
