This paper focused on the breeding of an L-lactic acid producing bacteria Lactobacillus easei YBQ1-1, studying the characteristics, medium components, pH and metabolic network of the mutant YBQH2-14 obtained after being selected.Using UV irradiation, L.casei YBQH2-14 was selected in the different plate media such as the medium with high concentration of glucose, lactic acid , CaCO3 -Bromocresol purple and KMnO4 -KBr.

本文主要对L-乳酸生产菌株(Lactobacillus casei YBQ1-1)进行了诱变选育，并研究了突变株YBQH2-14发酵条件对生产L-乳酸的影响，构建了L.caseiYBQH2-14的代谢网络模型，分析了分批发酵不同阶段的代谢通量，同时研究了L-乳酸的应用——黑麦麸皮粉发酵。

In this research work, the technology of microbial conversion was studied in order to establish an environment friendly method for the production of doxorubicin. A doxA gene encoding Daunorubicin C-14 hydroxylase was cloned from a daunorubicin-producing strain Streptomyces coeruleorubidus SIPI 1482. Some plasmids for the expression of doxA gene were constructed and transformed into S.

本研究对微生物转化法替代现有工艺生产阿霉素进行了探索，从柔红霉素产生菌天蓝淡红链霉菌SIPI 1482中克隆了柔红霉素C-14羟化酶基因，构建了doxA基因的链霉菌表达质粒，导入变铅青链霉菌TK24中获得了柔红霉素转化基因工程菌，并研究了doxA基因在工程菌中的表达，最后还对工程菌转化柔红霉素生成阿霉素的发酵工艺进行了初步研究。

ABSTRACT The final production of erythromycin by Saccharopolyspora erythraea was increased by 43.1% in 15L bioreactor with double quantily of soybean oil into culture medium. The final production, production capacity and Yp/s of erythromycin were improved 69.7%, 69.6% and 63.8%, respectively, in 15L bioreactor with added soybean oil during fermentation.
