A genome library of serratia marcescens cw - w - 90 - 3 strain was established by " shot gun " method and screened for phospholipase activity on lb - egg yolk plate 通过鸟枪法构建了粘质沙雷氏菌serratiamarcexcenscw - w - 90 - 3菌株的基因组dna文库。

Though serratia was not detected in nc89 , the isolation rate of serratia was also very low in the other cultivars . 5 不过对于内生细菌菌群来说，基本上没有什么明显差异，虽然nc89中没有分离到serratia ，但整个分离过程中serratia的分离频率都很低。

Identification of functional bacteria showed predominant ammonifiers were shewanella , variovorax , chryseobacterium , bacillus or aeromonas ; among 4 selected nitrogen fixers , one ( azorhizobium caulinodans ) belonged to . a - proteobacteria , the other three ( serratia marcescens , klebsiella pneumoniae and citrobacter freundii ) were enterobacteriace , which belongs to - proteobacteria ; 2 nitrate reducers were aeromonas sp . and citrobacter sp . , 对各功能菌群中的优势菌的鉴定表明，优势的氨化细菌为希瓦氏菌属，产碱菌属，黄杆菌属，芽孢杆菌属或气单胞菌属；分离到的4个优势固氮细菌菌株中，一株为基瘤固氮根瘤菌，属于-变形菌亚门，而另外3株都属于肠杆菌科，归于-变形菌亚门。
