| Abstract: | Single factor test and orthogonal test were used to study the technical process of the single cell protein by using erythromycin wastewater. Depending on the microbial biomass,the best conditions of SCP fermentation were determined, with the content of wastewater 20%,mixed bacteria inoculated by 6% and fermented on pH 6 for 72h. |
