| Abstract: | As one of the best utilization ways of kitchen wastes, methane production through anaerobic digestion was actually a synergctic biochemical process, which involved many micro-organisms. Enzymes activities, especially dehydrogenase and some hydrolases （β-glucosidase, EAA-hydrolysing production and phosphatase） during anaerobic digestion with yeast powder and chlorampherical were studied. Research results sh3wed that with the addition of yeast Fowder, compared with the control, the activity of dehydrogenase increased by 86%, and the production of methane increased by 100%, the activities of β-glucosidase and BAA-hydrolysing protease respectively increased by 46% and 62%. In contrast,compared with the control, with the addition of chloramphenicol, the activities of these three enzymes decreased by 31% ,22% and 35%, respectively. |
