添加酵母提取物和酪蛋白氨基酸刺激红串红球菌产生絮凝剂。絮凝剂形成的有利底物是果糖（或葡萄糖）、尿素和酵母提取物。生产絮凝剂的最适培养温度和最适培养pH为30 ℃。C和pH 8.5 apprx. 9.5，分别。过量曝气会降低絮凝剂的产量。絮凝剂的生成量呈曲线型增长。超过90%的酶活性在培养液中，而在细胞中的酶活性低于10%。
Addition of yeast extract and casamino acids stimulated the production of a flocculant by Rhodococcus erythropolis. The favorable substrates for flocculant formation were fructose (or glucose), urea, and yeast extract. Optimum culture temperature and optimum culture pH for the production of the flocculant were 30.degree. C and pH 8.5 .apprx. 9.5, respectively. Excess aeration decreased the production of the flocculant. The production of the flocculant paralleled the growth curve. More than 90% of the flocculating activity was in the culture broth and less than 10% in the cells.
