摘 要：Global depletion of energy supply due to the continuing over-utilization is a major problem of the present and future world *** is estimated that the fossil fuels will be exhausted in the next few *** today s energy demanding life style,there is always a need for exploring and exploiting new sources of energy which are renewable as well as *** digestion is a technology that utilizes various organic wastes（animal manure,energy crops and industrial wastes） to produce biofuel methane,which holds promise for the future while simultaneously addressing ecological and agrochemical *** the present study,kinetics of anaerobic digestion of dry water hyacinth,poultry litter,cow manure and primary sludge were undertaken in 250 ml biodigesters with 7% total solids and 60 days retention time and modified Gompertz equation was tested for its *** kinetic parameters viz.,biogas yield potential（P）,the maximum biogas production rate（Rm） and the duration of lag phase（λ） were estimated for each *** digester fed with poultry litter produced maximum biogas（0.39 l（g VS）-1） and kinetic parameters P,Rm and λ were 0.3904 l（g VS）-1;0.0165 l（g VS）-1d-1 and 8.7498 days respectively.
