This thesis deals with the isolation and identification of three phenanthrene - degrading bacteria from soil sample contaminated by oil , the factors influencing growth of phenanthrene - degrading bacteria and degradation of phenanthrene , the routes of phenanthrene degradation , the cloning and expression of catechol 2 , 3 - dioxynase gene of zx4 strain 本研究分離選育了3株菲降解細菌菌株,并研究了其中一株降解性能異常突出的分離菌株的生長特性、菲降解影響因素、降解途徑及部分的相關酶基因。

3 . zx4 strain could utilize catechol and salicylate , but not o - phthalate as sole carbon and energy source . research data have showed that phenanthren is degraded by bacteria through one of two different routes via a common inter - metabolite l - hydroxy - 2 - naphthoate 3 、 zx4菌株的降解底物廣譜性研究結果顯示, zx4菌株能以兒茶酚及水楊酸為唯一碳源微生物學碩士論文摘要和能源生長,而不能以鄰苯二甲酸為唯一碳源和能源生長。
