Production of microbial body protein was studied on soybean waste with T.viride,A.niger,S.cerevisiae and C.utilis by mixed culture solid state fermentation.Effects of four variable factors:components of medium,amount and comprising of inoculum,initial pH value and cultivation temperature were evaluated.It had been showed that the optimum conditions of the fermentation process were as follows:soybean waste∶wheat bran=8∶2,A.niger∶T.viride∶S.cerevisiae∶C.utilis=1∶1∶1∶3(inoculum size),initial pH value was 5.5 and cultivation temperature was 32℃.Under the optimum conditions,the amount of crude protein could be as high as 28.47%.It was about two times more compared with raw material.
