The investigation of flocculating the alkaline kaolin suspensions suggests that metal ions can affect the flocculate rate distinctly.

在实验室条件下确立了该菌株的发酵培养基组成和最适摇瓶发酵条件及絮凝剂使用的实验室最佳条件。

When the rotation speed was gradationally controlled 300 rmin^(-1 for 0~60 h, 500 rmin^(-1) for 60~120 h, 600 rmin^(-1) for 120~192 h, both the cell growth and product synthesis are promoted, and the maduramicin yield is 7.9% higher than that obtained with a fixed rotation speed.

采用分段控制搅拌速度的发酵工艺（0~60h为300rmin^(-1)，60~120h为500rmin^(-1)，120~192h为600rmin^(-1)），更有利于菌体生长和产物生成，马杜霉素发酵单位比固定转速时提高了7.9%。

Fermentation time, carbon content and inoculum influence to the liquid state fermentation were studied.

实验通过发酵培养时间，碳源含量，接菌量对液体发酵产木聚糖酶的影响分析，得出产木聚糖酶的最优条件，即在加入50 Mandels液体培养基，28℃条件下，底物含量为0.045g，接种量为20ml，培养36h。

The characteristic of pectinases production by solid state fermentation with Penicillium oxalicum BZH-2002 and lixiviation condition were investigated.

对草酸青霉菌BZH-2002菌株固体发酵果胶酶的特性及浸提条件进行了研究，确定其最佳产酶时期为72-92h，利用干物质量最快的时期为24-72h，发酵产酶期间培养基介质中pH值呈"V"字形变化。

The majority of them are produced by fermentation using microorganisms of different species identified as species belonging to Aspergillus, Monascus, Nocardia, Amycolatopsis, Mucor or Penicillium genus, and some are obtained by treating the fermentation products using the methods of chemical synthesis or they are the products of total chemical synthesis.

它们主要是用属于曲霉属，红曲霉属，诺卡菌属，Amycolatopsis，毛霉属或青霉属的不同物种的微生物通过发酵而生产的。有一些是用化学合成方法处理发酵产物而获得的或者有一些是全部化学合成的产物。

The fermentation characteristics of W39 is as follows: it can yield in the liquid the insoluble gel-like cellulose only with the existence of oxygen. The forming of nata needs uncovered surface of static liquid.
