Study on Biogas Fermentation by Adding Different Microbial Agent to Materials of Corn Straw—Pig Dung

Abstract

Adding different composite microbial agent to the crushed corn straw,the ability of biogas production of corn straw-pig dung was studied.The result indicated the total cumulative biogas production of corn straws pretreated by composite microbial agent was 10% higher than the treatment without composite microbial agent.The methane content was nearly equal,and the changing trend of the methane content with different treatment was accordant.
