研究了B族维生素对沼泽红假单胞菌生长和产氢的影响以及其对模拟废水的处理效果。考察了在基础培养基中加入不同配比B族维生素时的产氢状况和废水处理效果。结果表明,B族维生素对沼泽红假单胞菌的生长,产氢以及处理废水能力都是有影响的。从产氢量的角度来看,空白对照组(未添加任何B族系列维生素)的产氢量最少,产氢量累积达到57.88 mL/L,加入全部维生素累积量128.83 mL/L,缺少VB2的产氢累积为83.25 mL/L,低于加入全部维生素累积量,因此VB2对产氢有促进作用,而缺少VB4的产氢量累积高达337.43 mL/L,高于加入全部维生素累积量,因此VB4对产氢有抑制作用。而对于废水处理效果来看,只加入复合VB的COD去除率达到最高值64.706%。

The research aimed to discuss the effects of Vitamin B on cell growth,Hydrogen productivity with simulated wastewater by Rhodopseudomonas palustris.The hydrogen production and wastewater treatment conditions were investigated using the basic medium supplemented with different kinds of vitamin B.The results showed that vitamin B has an impact on the cell growth of Rhodopseudomonas palustris,hydrogen productivity and simulated wastewater treatment capacity.The results based on the hydrogen production suggested that the contrast group,which has not any vitamin B,was the minimum volume of hydrogen,and the cumulative yield was 57.88mL/L.The results also showed that VB2 was beneficial to produce hydrogen,the yield was 83.25mL/L when lacking of VB2,while it was 128.83mL/L when adding all kinds of vitamin B.The yield of 337.43mL/L when lacking of VB4 showed that VB4 inhibited hydrogen production.As for the wastewater treatment,only the vitamin B complex has highest COD removal rate of 64.706%.
