Bezos Center for Sustainable Protein Opens at Imperial College London, Will Receive $30M in Funding

The Bezos Earth Fund has announced the launch of a new Bezos Center for Sustainable Protein at Imperial College London. The Center will span seven academic departments, focusing on the development and commercialization of sustainable, affordable, nutritious, and tasty alternative food products. This will include research into cultivated meat, precision fermentation, AI, machine learning, nutrition, bioprocessing, and automation. Engineering biology and biofoundries (where cells effectively become mini factories) will be used to develop and scale up new bio-based processes. The Center will also encompass several institutes and facilities, including the Center for Synthetic Biology, the Center for Translational Nutrition & Food Research, and SynbiCITE (the UK’s industrial translation center for synthetic biology). These institutes will help with education, translating discoveries into real-world applications, and commercialization. …

UK Researchers Develop First “Self-Dyeing” Plastic-Free Vegan Leather from Bacteria

Imperial College London researchers have developed, using bacteria, a plastic-free, vegan leather that dyes itself black during production. Scientists and material companies have been using microbes to produce sustainable textiles or dyes for the fashion industry; however, the researchers claim this is the first time a material produces its own color pigment. One of fashion’s most environmentally damaging processes is dyeing with synthetic chemicals. The researchers explain that black dyes — especially those used for tanning leather — are particularly harmful.  To solve this environmental problem, the researchers genetically engineered the bacterium Komagataeibacter rhaeticus to simultaneously produce microbial cellulose and the dark pigment eumelanin. Their new process has been published in the journal Nature Biotechnology.  “Inventing a new, faster way to produce sustainable, self-dyed leather alternatives …

UK Project Develops Sustainable Microalgae Protein With Improved Flavour

The UK’s Natural Resources Institute (NRI) is collaborating with Imperial College London (ICL) and biotech startup Arborea to develop technology capable of producing sustainable microalgae protein with an improved flavour profile. Algae has attracted significant interest in recent years as a highly sustainable protein source. However, current protein extraction methods are inefficient, expensive, and produce a final product with undesirable off-notes. NRI will work to identify the compounds responsible for these flavours, and examine how they can be altered through changes in growth conditions and extraction methods. Meanwhile, ICL will develop cost-effective and environmentally friendly methods of producing algal protein extract, while Arborea — which has develped patented bioreactor technology — will contribute its expertise in the industrial growth and harvesting of microalgae. The two-year …
