摘要

为了促进马铃薯发酵产氢

研制了改良培养基驯化产氢菌株并使用淀粉生物酶降解马铃薯.将活性污泥煮沸后作为产氢菌株的接种体富集培养

使用Cl

代替SO

改良传统培养基消除了传统发酵产氢的启动滞留期(约12 h)

单位最大产氢速率从703.4 mL/(g·d)提高到800.5 mL/(g·d)

最大产氢潜力从205.2 mL/g增加到218.2 mL/g.通过α淀粉酶和糖化酶处理进一步提高了马铃薯的发酵产氢能力

单位最大产氢速率进一步提高到944.7 mL/(g·d)

最大产氢潜力进一步提高到267.2 mL/g.生物气中氢气的体积分数为43%～69%

无甲烷.

Abstract

In order to improve the hydrogen production from potatoes

the bacteria substrate was improved to domesticate H

-producing bacteria and potatoes are degraded by enzyme. The boiled activated sludge was used as H

-producing bacteria inoculum. While using the improved substrate

in which Cl

was used to substitute for SO

a lag-phase time(about 12 h)vanished

the maximum specific hydrogen production rate increased from 703.4 mL/(g·d)to 800.5 mL/(g·d)and the maximum hydrogen yield increased from 205.2 mL/g to 218.2 mL/g. When potatoes were pretreated by a amylase and glucoamylase

the hydrogen production was further enhanced. The maximum specific hydrogen production rate was then increased to 944.7 mL/(g·d

)and the maximum hydrogen yield was increased to 267.2 mL/g. It is found that the hydrogen composition of the biogas is about 43%～69% and no methane is detected.
