Singapore scientists replace fish feed with microbial protein extracted from soybean wastewater

Singapore scientists have found a way to replace feed for fish farming with a kind of protein extracted from the wastewater that is used to process soybeans. This could mean more sustainable fish farming of certain species, such as the Asian seabass. Their feed is typically made from wild-caught fish stocks, which are depleting in the oceans. It's hoped that this new method could cut waste and improve food security. Dr Diana Chan, head of the Aquaculture Innovation Centre at Temasek Polytechnic, and Professor Stefan Wuertz from the School of Civil and Environmental Engineering at Nanyang Technological University, shared more about the cultivated protein.
