MEDIA OPTIMIZATION FOR BIOPROTEINS PRODUCTION FROM CHEAPER CARBON SOURCE

There are high demands for animal and human food supply especially protein,which is an important dietary component. Agricultural wastes, cheap carbonsources- which are rich and have high energy, can be used for producing thevalue added bioprotein. A lab scale study was carried out to optimize the mediacomposition for bioprotein production from a cheaper carbon source - wheatflour using potential strain, which was selected earlier by screening differentmicroorganisms. The performance of the selected strain was enhanced by mediaoptimization with varied substrate concentration, nitrogen sources and nutrientsupplementation according to the central composite design from STATISTICAsoftware. Statistical optimization was carried out to evaluate the polynomialregression model through effect of linear, quadratic and interaction of thefactors. The maximum biomass produced was 21.89 g/L with optimumfermentation conditions of wheat flour (4 g/L), nitrogen concentration (0.5 g/L),nutrient concentration (0.1 g/L), and four days of fermentation.
