Microorganism Bacteria Colony to Enhance Biogas Output
Two kinds of anaerobes were screened and cultivated in laboratory,which were anaerobic hydrolytic mixed bacteria A and anaerobic cellulose decomposing mixed bacteria B.In the use of the two kinds of anaerobes,effect on aerogenic yield from swine excrement methane was studied with three different formulas composite bacteria,with aerogenic yield of the groups increased by 28.08%,24.93% and 32.95% respectively.Utilization factors of raw stuff TS were increased from three formulas,which were increased by 9.42%,6.02% and 11.78% respectively,compared with the control group.Results showed that both of two composite bacteria as a prospective methane fermentation bioactive additive were propitious to advance the aerogenic yield of swine excrement methane and utilization factor of raw stuff.
