Coutteau, P.; Lavens, P.; Sorgeloos, P. (1990). Baker's yeast as a potential substitute for live algae in aquaculture diets: Artemiaas a case study. J. World Aquacult. Soc. 21(1): 1-9

In this study baker's yeast was evaluated as a substitute for live Dunaliella tertiolecta algae in the culture of the brine shrimp Artemia. Consumption of fresh baker's yeast resulted in poor growth and survival of brine shrimp. However, the nutritional value of the yeast significantly improved after complete removal of the yeast cell wall by enzymatic treatment. Baker's yeast was also made digestible for Artemia by simple chemical treatment which did not reduce rigidity of the yeast cell. The external mannoprotein layer of the yeast cell wall is probably the major barrier to digestion by Artemia. Chemically treated baker's yeast offers promising possibilities as a substitute for algal feeds in aquaculture.
