摘要
从不同林分的油茶根系分离筛选出1株固氮效能最高的联合固氮菌N7-3,通过对该菌株的形态特征、生理生化特性以及Biolog微生物鉴定系统进行鉴定,结果表明:该菌株是革兰氏阴性菌,椭球菌,不产芽孢,能运动,菌落白色、圆形,凸起,边缘整齐,有光泽。经Biolog系统鉴定,该菌株是Azomonasspp.的可能性为95%,其主要生理生化特征也与Azomonas相符。
A strain of the associative nitrogen fixation bacteria N7-3 with the highest nitrogen-fixing efficiency was isolated and screened from the rhizosphere of different Camellia oleifera forests and it was identified by morphological, physiological characteristics and biolog microbes identification system. The results showed that the strain was gram-negative coccus and non-endospore and motorial. Its colonies were white, rounded, convex, tidy edge with luster. The homologous between N7 -3 and Azomonas spp. was 95% , and the main biochemical and physiological characteristics of N7-3 were similar to that of Azomonas spp.
