一株分离自潮间带污泥细菌Clostridium sp.T7产氢特性分析
Characterization of Hydrogen Production of a Strain Clostridium sp.T7 Isolated from Intertidal Sludge
摘要
Abstract
A hydrogen-producing bacterium, Clostridium sp. T7, was isolated form the sludge collected from intertidal zone of a bathing beach in Tianjin. The effects of initial pH value, carbon source, nitrogen source and NaCl concentration on hydrogen production of strain T7 were determined in this study. The results showed that strain T7 produced hydrogen production at maximal level when growing at initial pH of 6.0. The strain was able to produce hydrogen using many carbon sources, such as glucose, sucrose and fructose. The strain T7 could produce hydrogen by using yeast extract and beef as nitrogen source, but not peptone. The level of hydrogen production was affected by the salt concentration. In marine conditions (NaCl concentration as 3%) .hydrogen production was(1.48 ± 0.05)mol/mol glucose,whereas,it increased by 20% in fresh conditions. It could produce hydrogen at the NaCl concentration from 0.4% to 7%. As a result, Clostridium sp. T7 can be considered to be used for bio-hydrogen production and biological treatment of fresh or marine organic waste.关键词
