A statistical design approach has been used to optimize the production of biomass by Cunninghamella sp. 2A1, evaluated based on lipidless biomass. A 2 3 full factorial central composite design (CCD) was chosen to study the combined effects of three factors; ammonium tartrate, peptone and glucose concentrations. The p-value for each factors was < 0.05 suggesting that these factors have significant effect on the production of lipidless biomass. The production is represented by a linear model with p-value < 0.0001. The optimized medium consists of 3.86 g/l ammonium tartrate, 55.84 g/l glucose and 7.73 g/l peptone predicted 16.83 g/l lipidless biomass. Results from four replications based on the optimized medium produced 18.48 g/l lipidless biomass, which are in close agreement with the predicted value. The coefficient for glucose was the highest indicating it as the most significant factor affecting lipidless biomass production.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
