Abstract

Anaerobic biodigestion of various wastes such as groundnut, shell, press mud, end paddy husk a long with cowdung using biodigested slurry as a source of microbial inoculum was studied with respect to gas generation and microbiological activity. The maximum gas output of 12, 173 ml besides maximum methanogenic activity (222.3 x 10g) was observed in pressmud incorporated with cowdung. treatment followed by groundnut shell mixed with cowdung of 11962 ml and 189.66 x 10/ during the final stage of digestion, respectively, over a period of 12 weeks. The data obtained indicated the suitability of mixing pressmud and groundnut shell as supple- mentary feedstocks for biogas production.
