摘要:
为研究石油污染土壤的生物修复技术,利用正交试验法对假单胞菌Pseudomonas sp.ZL13和产碱菌Alcaligenes sp.ZL21两株原油生物降解菌株的降油影响因素和最优降解条件进行了研究。通过气质联用方法分析两株菌对原油不同组分的降解能力,结果表明:影响两株菌降解的重要因素是原油浓度和温度;在最优降解条件下,菌株ZL13和ZL21的7d原油降解率分别为72.68%和73.10%;菌株ZL13和ZL21对原油大多数组分都有较高的降解能力,ZL21的降解效果要略优于ZL13。
Abstract:
To study the bioremediation technology of the petroleum contaminated soil,the influential factors of petroleum biodegradation and the optimizing degradation conditions of two petrolecm-degrading strains of Pseudomonas sp.ZL13 and Alcaligenes sp.ZL21 are researched by orthogonal test.Their degradation ability for different components of the crude oil is studied by the technology of gas chromatography-mass spectrum(GC-MS).The results show that the influential factors of two strains are oil mass concentration and temperature.Under the optimum conditions,the crude oil degradation rates by ZL13 and ZL21 after seven days’ incubation is 72.68% and 73.10%.The two strains can effectively degrade most components of the crude oil.The degradation ability of strain ZL21 is better than that of strain ZL13.
