Growth Characteristics and Fermentation Kinetics of Flocculants-Producing Bacterium F2

摘要

We isolated flocculants-producing bacteria F2 from soil. It shows high and stable flocculating activity for Kaolin clay suspension. In order to comprehend their growth characteristics to make good use of them, we measured the changes of several parameters using shaking flask experiment, including pH, temperature, the content of glucose and nitrogen source. And we built the model about the cell growth and substrate consumption. Through the comparison of experimental data and the corresponding calculated values from the models, we found that the data joint well and the model can provide theoretical basis for large-scale fermentation of flocculants-producing bacteria F2.
