To investigate the mechanisms of biohydrogen production by anerobic fermentation of solid organic waste, gas chromatography is used to analysis the biogas and volatile fatty acid in anaerobic bio-reactor. Firstly, the ability of hydrogen production by digested sludge from the West Lake, Enteobacter aerogences, digested sludge from sewage farm, the fluid of methane pool and dejecta have been studied. The rule of the ability of hydrogen production by different bacteria under different control condition. Simultaneity, the importance of the synergistic effect on hydrogen production has been proved.

本文首先选用西湖底的厌氧活性污泥、产气肠杆菌、污水处理厂的淤泥、沼气池发酵液以及猪粪等不同菌群对废弃食物——马铃薯进行厌氧发酵产氢特性实验研究，得到马铃薯在各不同菌群及工况下的发酵产氢能力，同时发现产氢菌间的协同作用很重要，在控制好发酵条件的情况下，产氢菌群发酵通常会好于单一产氢菌的发酵。
