Abstract


          The human demands for energy and conservation of healthy environment have driven the development of cellulosic wastes into new generation of bioenergy.  Ethanol was the first generation of biofuel developed to lessen dependence on fossil fuels. Efficiency of conversion of cellulosic material into simple sugars was the driving force behind search for strong cellulose-degrading microbes; Termites was chosen to be an excellent candidate to find such microbes. Six bacteria were isolated from the Termite's guts where their cellulose degrading activities were screened using carboxymethyl cellulose as a substrate and Congo red as an indicator. Only one isolate showed a relatively higher cellulolytic activity and biogas production. This isolate was identified by a variety of methods including the MALDI-TOF MS and turned out to be Enterobacter cloacae. The ability of this bacterium to degrade cellulose and produce biogas qualifies it for further development at genetic levels and biotechnological levels to produce biogas from cellulosic wastes.
