| Summary: | There are high demands for animal and human food supply especially protein,
which is an important dietary component. Agricultural wastes, cheap carbon
sources- which are rich and have high energy, can be used for producing the
value added bioprotein. A lab scale study was carried out to optimize the media
composition for bioprotein production from a cheaper carbon source - wheat
flour using potential strain, which was selected earlier by screening different
microorganisms. The performance of the selected strain was enhanced by media
optimization with varied substrate concentration, nitrogen sources and nutrient
supplementation according to the central composite design from STATISTICA
software. Statistical optimization was carried out to evaluate the polynomial
regression model through effect of linear, quadratic and interaction of the
factors. The maximum biomass produced was 21.89 g/L with optimum
fermentation conditions of wheat flour (4 g/L), nitrogen concentration (0.5 g/L),
nutrient concentration (0.1 g/L), and four days of fermentation. |
