Abstract:With processed scallop disposal as raw materials, microzyme, Lactobacillus plantarum, Lactobacillus bulgaricus, Streptococcus lactis were selected to ferment raw materials for producing the high quality protein feed. The optimal strains combination was screened based on amino nitrogen content and crude protein content, and the best proportion of the species was determined. The results showed that the amino nitrogen content and crude protein content could increase by compound culture of microzyme and Lactobacillus. The compound culture of Microzyme, Streptococcus lactis and Lactobacillus bulgaricus was found to be the most suitable for the fermentation, and the best proportion of the three species was 3:1:1. In this condition amino nitrogen content and crude protein content were 3.52% and 61.63%, respectively.
