摘要：研究了pH值、接种量、葡萄糖浓度、盐浓度、转速以及温度等因素对烃类降解菌HJ-1的发酵过程中细菌密度的影响,得到了该细菌发酵的适宜条件,然后将优化条件下发酵的菌液添加到炼厂含油污泥中进行一次发酵处理。结果表明,菌株HJ-1对原油中的油降解率由78.6%提高到82.0%,对含油污泥中的油降解率由69.4%提高到77.4%。
The influences of pH value, microbe amount, glucose concentration, salt concentration, rotation speed and temperature on bacterial density during fermentation of hydrocarbons degrading strain HJ-1 were investigated, and optimal fer-mentation condition of HJ-1 was obtained. Then the fermentation bacteria solution was added into the oily sludge at once un- der the optimization conditions. The results show that oil degradation ratio of strain HJ-1 rises from 78.6% to 82.0% for crude oil and from 69.4% to 77.4% for oily sludge from refinery.
