To reduce the toxic substance and raise the protein content of the rapeseed hull,the rapeseed husk power treated with Aspergillus niger was fermented with the yeast strain broth.The feed protein yield were compared with those fermented by Saccharomyces cerevisiae and Candida dattila.The protein content in the dry products of final fermentation by the yeast strain A was 22.48%,which was 73.2% higher than that in the original rice husk powder(12.98%).In addition,it was 53.45% higher than that in the final fermentation products by Saccharomyces cerevisiae(1...
