Study on the Way of Preparation of Single Cell Protein
Kitchen trash, straw and starch waste water contains abundant organic matter. The purpose of this experiment was to degrade organic waste as well as generate single cell protein. In this study, we disposed slightly kitchen trash, etraw and starch waste water which were regarded as fermentation medium which provide nutrients for yeast and Bacillus subtilis. In the second days after fermentation, we measured the production of the microbial single cell protein through the medium of the determination of OD600 (optical delnsity) and the degradation of organic waste through the determination of COD (Chemical Oxygen Demand). In conclusion, after the second days of fermentation, the OD600 of kitchen trash and starch wastewater that the degradation of COD was 80-95% was 1.8-2.0, when the OD600 of straw that the degradation of COD was 20% was 0.2. In conclusion, kitchen trash and starch wastewater could be fermented by yeast and Bacillus subtilis to make single cell protein through experimental data, but straw could not be fermented.
