液体菌种在我国已经 有四、五十年的历史了, 也曾有许多单位和个人以 各种形式推广过,但均未 获得成功。其中最主要的 原因是污染高、风险大, 尤其是污染问题一直是困 绕液体菌种推广的最大障 碍,其主要原因如下: 一、设备不合理以 前的设备采用摇床、简易 的三级反应器、反应釜改 制的圆柱形发酵罐等三种 形式。所以往往一淡到液 体菌种都联想到污染。 二、技术繁琐难度大 以前无论采用哪种设备 生产液体菌种,其工艺都 是由固体斜面母种转制摇 瓶种,再由摇瓶种扩繁液 体菌种。
Liquid bacteria in our country have been four or five years of history, there have been many units and individuals to promote in various forms, but have not been successful. The main reason is that the pollution is high and the risk is high. In particular, the pollution problem has always been the biggest obstacle to the promotion of liquid bacteria. The main reasons are as follows: First, the equipment is unreasonable Previous equipment used a shaker, a simple three-stage reaction Reactor reactor modified cylindrical fermenter and other three forms. So often a light to liquid bacteria are associated with pollution. Second, technical complexity Difficult before no matter what kind of equipment used in the production of liquid bacteria, the process is from the solid beveled mother Shake Sharpening species, and then shake the flask species to expand the proliferation of liquid bacteria.
