Culture Conditions for Production of Microbial Flocculant by Rhodococcus erythropolis

摘要: Addition of yeast extract and casamino acids stimulated the production a flocculant by Rhodococcus erythropolis. The favorable substrates for formation were fructose (or glucose), urea, extract. Optimum culture temperature optimum pH 30°C 8.5 ~ 9.5, respectively. Excess aeration decreased flocculant. paralled growth curve. More than 90% flocculating activity was in broth less 10% cells.
