Influence of some nutritional factors on cellulase and single cell protein production by aspergillus niger from beet pulp

ABSTRACT

Production of cellulose and single cell protein [SCP] by Aspergillus niger isolate No I grown on beet pulp [BP] waste, as the sole carbon source, were optimal when the culture medium was composed of [g/I] BP, 25; NaNO[3]2; MgSO[4],. 7H[2]O, 0.57;K[2]HPO[4], 1. Microelements solution in the cultivation medium did not significantly affect the fermentation activities. On the other hand, supplementation of yeast extract [2g/1] to the medium permitted maximal cellulase and SCP production
