12 Nov 2019 --- A new production method of producing ergothioneine could provide a way of supplying the natural amino acid at a much lower price. Because of current expensive chemical production routes, market prices of ergothioneine are very high compared to other nutrients such as vitamins C and D. The scientists are now trying to increase productivity by engineering the strain further to make a commercially viable product. If successful, they will be able to bring an affordable product that could help fight brain diseases and other illnesses by preventing cellular stress to a broader market.
