Sulfur transformation of a facultative autotroph bacterium 一株兼性自养菌硫转化性能的研究

the gene mutagenesis was used to construct MTB attenuated live vaccine such as MTB purine autotroph, ICL gene deletion,VitB 5 autotroph and undecaprenol kinase mutant. 利用基因诱变可构建 MTB减毒活疫苗,如MTB嘌呤营养缺陷株, ICL基因剔除株,VitB5营养缺陷株和十一萜 醇激酶基因变异株。

"autotroph:an organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. Green plants, algae, and certain bacteria are autotroph s." 自养生物:一种能够从无机物质如光或化学能量中合成出自身食物的有机体。绿色植物,海藻及某些细菌都是自养生物。

obligate autotroph 专性自养生物

chemosynthetic autotroph 化能合成自养菌

facultative autotroph 兼性自养生物
