Title: Research on production of protein feed from waste food fermented by multi-strains
Abstract: By a serial of single factors and orthogonal design(L934)tests,the fermentation conditions of producing protein feed from waste food were optimized.Results showed that the optimal conditions were: fermentation time 24 h,Candida utilis C01∶Saccharomyces cerivisiae S0201∶Lactobacillus plantarum L0211 6∶3∶1,(NH4)2SO4 2.5%,waste food∶ wheat bran 6∶4,inoculum size 3%,fermentation temperature 30℃.Under optimized conditions,the true protein content and the increase rate of true protein after fermentation were 18.02% and 75.84%,respectively.Enlarged scale tests revealed that true protein content and the increase rate of true protein under controlled fermentation temperature were 17.56% and 71.35%,respectively,much higher than those without controlled(12.45%,21.25%).Chemical analyzing of final product showed that its chief constituents were saccharide,crude protein and crude fattiness,their contents were 32.24%,26.21% and 20.23%,respectively.
