Study on production of protein feed by solid fermentation with tomato residue

In this paper,mixed bacteria ratio in tomato peels fermentation was studied. On the basis of a single fermentation bacteria experiment,the pairs of strains,and three strains of different mixing ratio fermentation experiments,the proportion of mixed bacteria to achieve highest protein content was determined. The results showed that the optimal ratio was that 1∶ 2∶ 6 of Trichoderma viride∶ Aspergillus niger∶ Candida tropicalis,which was the best strains combination. Under this condition,after fermentation of tomato peels,the crude protein content was 35. 00%.
