摘要
通过对海藻酸钠、琼脂、卡拉胶3种固定材料的研究,确定海藻酸钠作为酵母菌的固定载体;在对固定酵母菌种的培养时,溶氧量对菌数影响最大,是决定菌总数的最重要因素,温度影响次之,pH值影响作用最小;固定化细胞在发酵液中增殖时,在25h^35h后停止是适宜的;发酵时加入的固定化粒子是发酵液的8%时最适宜。
Sodium Alginate was chosen as the vector of yeast after compared three immobilized materials （Sodium Alginate, Agar, carrageenan）. It was found that dissolved oxygen content was the most important factor influencing bacteria number, followed by temperature, and pH had little effect. It was suitable to terminate the proliferation of cells after 25h-35h, and the optimum amount of immobilized particles was 8% of the broth weight.
