摘要:
从合肥王小郢污水处理厂的污水池污泥中驯化分离得到1株高效降解2,4-二氯酚的菌株W-1,初步鉴定该菌株为假单胞菌属。研究表明:W-1菌株降解2,4-二氯酚的适宜条件为pH6.0、35℃、240 r.min-1。在此条件下,当2,4-二氯酚质量浓度为50 mg.L-1时,培养48 h,2,4-二氯酚降解率可达88.5%;添加50 mg.L-1的碳源(葡萄糖、淀粉、麦芽糖等)或氮源(蛋白胨、酵母膏、尿素等)对该菌株降解2,4-二氯酚无强化作用;添加0.32 mmol.L-1Fe2+、Al3+、Cu2+、Mn2+、Ba2+和Co2+对该菌株降解2,4-二氯酚能力均具有不同程度的抑制作用。
Abstract:
An efficient 2, 4-dichlorophenol-degrading W-1 strain was screened from the sludge of the wastewater of treatment and was identified as Pseudomonas sp. . The suitable conditions for degradation are pH 6.0, 35 ℃ and 240 r·min-1, in which the highest degradation rate might reach 88.5% after 48 h when medium contained 50 mg·L-1 2, 4-dichlorophenol. 50 mg·L-1 carbon source(glucose, starch, maltose, etc. )or 50 mg·L-1 nitrogen source(peptone, yeast extract, urea, etc. )couldn′t increase degradation, but 0.32 mmol·L-1 metal ions(Co2+, Ba2+, Al3+, etc. ) had different inhibition on the degradation of 2, 4-dichlorophenol by W-1 strain.
