丝瓜瓤固定化脱色菌Enterobactor sp.S8对活性黑5的脱色
Decolorization of Reactive Black 5 by strain Enterobactor sp.S8 immobilized on Luffa cylindrica sponge
摘要
Abstract
The decolorization of Reactive Black 5 by Enterobactor sp.S8 immobilized on Luffa cylindrica sponge was studied.The effects of bacteria age,bacteria amount,pH and temperature on decolorization were discussed.The reusability and kinetics of the immobilized bacteria were also studied.The results showed that the optimum conditions for decolorization by immobilized bacteria were 3-day culture,inoculation of 2%,temperature of 30℃,and pH 6.0.The decolorizaton of immobilized bacteria on Reactive Black 5 under various initial concentrations conformed to the second-order reaction mode.After nine times reused,the decolorization rate of the immobilized bacteria could still reach 76.8%.According to the UV-Vis spectrum before and after 3 d degradation under the optimum conditions,Reactive Black 5 was not completely mineralized to CO2and H2O.Instead,some organic intermediates were produced.关键词
