Scientists in Singapore replace fishmeal in aquaculture with microbial protein derived from soybean processing wastewater

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and Temasek Polytechnic have successfully replaced half of the fishmeal protein in the diets of farmed Asian seabass with a "single cell protein" cultivated from microbes in soybean processing wastewater, paving the way for more sustainable fish farming practices. The findings are published in the journal Scientific Reports.The use of a cultivated protein is new to aquaculture production, say the scientists from the Singapore Centre for Environmental Life Sciences Engineering (SCELSE) leading NTU's efforts in the study, and Temasek Polytechnic's Aquaculture Innovation Centre (AIC).Farmed aquaculture species rely heavily on feed made from wild-caught fish, known as fishmeal, which is not sustainable and contributes to overfishing of the seas.Single cell protein, a sustainable alternative, can be cultivated from food processing wastewater. In particular, the wastewater from soybean processing contains ...
