SynBio Team

As a student research team at the University of Stuttgart, we are combining expertise in synthetic biology and chemistry to work towards a more sustainable future. Our current project will be presented internationally at the iGEM competition 2025 in Paris.

some facts about us and our project!

Pt 30%
Pd 33%
Rh 40%

The overall recycling rates of the major PGMs, Platinum (Pt), Rhodium (Rh) and Palladium (Pd) from secondary sources are relatively low. The research about bioleaching has continuously increased in the last 10 years, highlighting its importance.

Ashish Pathak, Hanadi Al-Sheeha, R. Navvamani, Richa Kothari, Meena Marafi, and Mohan S. Rana. Recycling of platinum group metals from exhausted petroleum and automobile catalysts using bioleaching approach: A critical review on potential, challenges, and outlook. 21(4):1035–1059.

Project Overview

In times of resource scarcity, global warming and overexploitation, it is our duty to find methods of responsible recycling. This was our mission with this project.
Our aim is to recycle valuable platinum group metals (PGMs) using a novel bioleaching method from exhausted automobile catalysts and even street dust. The project includes:

  • Engineering C. glutamicum for efficient Oxalic acid production
  • Using Oxalic acid as a leaching agent for PGM recovery from automobile catalysts
  • Presenting our project to various audiences, including the iGEM competition
  • Educational work at local schools and events on synthetic biology, sustainability and our project
  • Creating theoretical models for oxalic acid production

Bioleaching advantages

  • Environmentally friendly
  • Cheap
  • Fast
  • Safe

Possible applications

  • Automobile industry
  • Battery usage
  • Street cleaning
  • Possible anode/cathode catalysts for H2 fuel cells

Subgroups

The project is brought forth by different subgroups. Click below to find out what they do and how they collaborate.

BioTech Group

BioTech

We develop solutions for all bio-related questions. Our work involves strain engineering, cultivations from shake flask up to stirred-tank-reactor scale as well as developing analytical methods for Oxalate quantification in biosuspensions. Apart from wet-lab work, we create theoretical models for e.g. Oxalate production

Chemistry Group

Chemistry

The Chemistry Group is responsible for research on the leaching process and complex separation.

Finances Group

PR

Our work mostly focuses on the promotion and the acquisition of our project. Participating at the iGEM competition is very expensive/ has grown very expensive over the past years and our team faced that challenge by net-working with various institutions at the university related with Biology like the Stuttgarter Research Center for System Biology and with many (major) companies like Audi which all supported our vision with financial aid as well as with promoting our project further. Additionally, we keep people constantly informed about all activities, successes and break-throughs on our Instagram channel and on this website Don't miss to also check out the work of the other teams. Enjoy !
