中文拼音 [dàndānbāojūnzhǔ]
氮單胞菌屬
英文
azomonas-
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.,
對各功能菌群中的優勢菌的鑒定表明，優勢的氨化細菌為希瓦氏菌屬，產堿菌屬，黃桿菌屬，芽孢桿菌屬或氣單胞菌屬；分離到的4個優勢固氮細菌菌株中，一株為基瘤固氮根瘤菌，屬于-變形菌亞門，而另外3株都屬于腸桿菌科，歸于-變形菌亞門。The results of the experimental tests show that nh4cl and k2hpo4, kh2po4 are the most available nutrents to our isolates when they are degrading oils. the most suitable experinment condition is : temperature being 30 c, initial ph being 7 - 8, the shaking rate of the culture flasks is 180 r / min, the concentration of nacl is 1 %. the biodegradation results have shown that our 6 isolates have the effective degradation capability to crude oil ; within 6 days the transforing rate of oil by each single strain is more than 60 %
本研究分離出的6株菌，初步鑒定結果為： sy1為微桿菌屬、 sy2為諾卡氏菌屬、 sy3和sy5為假單胞菌屬、 sy4和sy6為芽孢桿菌屬；實驗結果表明， 6菌株的最佳氮源為氯化銨（ nh _ 4cl ） ，最佳磷源為磷酸氫二鉀和磷酸二氫鉀的混合物，最適生長條件為：溫度為30 ，初始ph值為7 8 ，搖床轉速為180r min ，鹽（ nacl ）濃度為1 ；通過降解實驗得出6株菌對原油都有較強的降解能力，單一菌株在5天後的原油降解率都高於60 ， 6株菌對原油的生物降解反應符合一級反應動力學特徵。
