Growth characteristics of strains for single-cell-protein produced by yellow slurry water and molasses

The crude protein,non-protein nitrogen,total sugar,reducing sugar,phosphorus,moisture,crude ash,lutein,elemental of the Yellow Slurry Water and molasses in the trash of the corn after extracting crystal sugar were analyzed.And then,selected Candida utilis,Geotrichum candidum and Candida tropicalis,three kinds of industrial yeast,as the strains fermented the mixture of yellow slurry water and molasses for single-cell-protein by shaking flask,the growth characteristics of three types of yeast was studied.And the best strain combination for production was screened.The results showed that the dry mass of the single-cell-protein can reach 5.87g,and the protein can reach 1.78g/100mL,when it was fermented by equivalent Geotrichum candidum and Candida tropicalis.
