摘要：During this century, sustainable development programs focusing on global environmental concerns such as conservation of energy, preservation of water and management of environment through appropriate alternatives and technologies. In this context, biogas production technology has been developed and proven successful presently. In recent past, research on this technology has limited on some instances like optimization of different substrate and parameters like temperature, pH, total solid concentration, retention time, etc. A critical analysis reveals that few issues associated with the system used for biogas production at present, while various prospects lifted during the review gives an opportunity to enhance biogas production using advance techniques in future. Pretreatment of lignocellulosic substrate, incorporation of biological, chemical or inorganic additives and enzymes to the substrate were found as effective for increasing biogas production. Another interesting trend in this field is the development of potential microorganism for enhancing biogas production through gene manipulation. Multi-stage processes with separation of hydrolysis, acidogenesis, acetogenesis and methanogenesis would provide biological stability for each step which absolutely enforces the reaction at temporal dimension.
