Effect of the nitrogen and phosphorous source on the cell wet weight and ethanol content of glucoamylase expressing strain CIBTS1522. The influence of the nitrogen source urea (a) and (NH4)2SO4 (b). The influence of the compound inorganic nitrogen and phosphorous sources (NH4)2HPO4 (c) and NH4H2PO4 (d) on these parameters. Error bars represent the standard deviation from the mean of three replicates
