| 摘 要： | 从石油化工厂附近的污染土壤中分离到三株石油降解菌w1、w2和w3,经鉴定分别是不动杆菌属、芽孢杆菌属和假单胞菌属。初步研究了菌株的生长特性与其降解石油能力的关系,并将w1和w2进行紫外诱变得到诱变菌yw1和yw2。对诱变前后的菌株进行石油降解实验,结果表明,诱变前的菌株在原油浓度为4000mg/L培养液中培养10d,原油的降解率分别为74.34%和77.58%。而诱变菌株10d降解率达到了79.9%和87.3%。同时,诱变菌株还大大提高了对高浓度石油的耐受能力。

| Abstract: | Three bacteria strains were isolated from petroleum contaminated soil near a petrochemical plant:Acintobacter,Bacillus and Psuedomonas.After culture and UV-induced mutation,bacteria yw1,yw2 and yw3 were obtained.The study reported that the bacteria after being UV-induced mutated improved their oil degradation ability. |
