Distribution of Flocculating Activity and Condition Optimization for the Microbial Flocculating-producing Bacteria
Jinhua Wang · Journal of Hubei University of Technology · 2012
Microbial flocculant-producing bacteria EA was used as initial strain,the distribution of flocculating activity of which was analysed and then the fermentation condition was optimized.Different carbon sources and nitrogen sources were chosen to carry out comparison tests.The initial culture pH,cultivation temperature,inoculation size were optimized through single factor experiment and orthogonal experiment.The results indicated that glucose and yeast extract were the best carbon source and nitrogen source,and the best cultivation condition was initial pH of 7.5,cultivation temperature of 37℃,inoculation size of 4%.The flocculating activity could achieve 78.5% under the best conditions.
