Mesophilic methane fermentaiton using bagasse as the raw material was examined, and the following results were obtained.The effeiciency of the methane fermentation was greatly improved by previous treatment of the bagasse with dioxane or dioxilane followed by incubation with cellulo- and hemicellulolytic enzymes. The gas evolved from the bagasse thus treated and fermented with a supply of a small amount of L-glutamic acid amounted to nearly 200 ml per g bagasse with a methane ratio of 68%.The bagasse terated with ammonium hydroxide, Cadoxene or Zunkoxene followed by incubation with cellulo- and hemicellulolytic enzymes also resulted in good gas evolution. However, the gas evolived contained much lower ratios of methane.Analysis of the mash before and after fermentaiton suggested that the stimulative effect of L-glutamic acid for evolution of methane was attributed to the increase in formation of various volatile fatty acids readily convertible to methane in the fermentation environment.
