摘要

目的:从尼日利亚阿库雷选定的河流中分离、表征和鉴定表面活性剂降解细菌，并比较和量化每种分离细菌的生物降解潜力。研究地点:2013年6月至11月，尼日利亚翁多州阿库雷市。方法:采用在培养基中添加试验表面活性剂的方法，从水样中分离表面活性剂降解菌。分离的细菌随后进行烷基硫酸酶测定，以量化其各种酶的产量/活性。结果:水样细菌总负荷范围为7.20±0.69 × 10 3 cfu/ml ~ 40.0±2.31 × 10 3 cfu/ml，表面活性剂降解细菌数量范围为3.30±0.02 × 10 2 cfu/ml ~ 5.37±2.3 × 10 3 cfu/ml。恶臭假单胞菌与烷基硫酸酯酶表面活性剂的降解

Bacteria Associated with Selected Rivers in Akure, Nigeria and their Alkysulphatase Activity/Production

Aims: To isolate, characterize and identify surfactant degrading bacteria from selected rivers in Akure, Nigeria and also to compare and quantify the biodegrading potentials of each of the bacterial isolates. Place of Study: Akure metropolis, Ondo state, Nigeria, between June and November, 2013. Methodology: Surfactant degrading bacteria were isolated from the water samples by supplementing culture media with test surfactant. The bacteria isolated were later subjected to the alkylsulphatase enzyme assay to quantify their various enzyme production/activity. Results: The total bacterial load of the water samples range from 7.20±0.69 x10 3 cfu/ml to 40.0±2.31 x10 3 cfu/ml, while the surfactant degrading bacteria counts was within the range of 3.30±0.02 x10 2 cfu/ml to 5.37±2.3 x10 3 cfu/ml.
