Biogas, essentially a mixture of methane (CH4) and carbon dioxide (CO2), can be used to generate electricity and heat or as bio-methane (bio-CH4). Bio-CH4 can be utilized in all applications in which natural gas is used today. Biogas is generated by a complex microbial community in nature and in man-made biogas reactors. An understanding of the interactions between the members of such communities and the build-up of the networks of microbial complex systems is extremely important. Culture-dependent methods cannot supply sufficient information about the life of microbial community. However, since the birth of molecular biology, more accurate taxonomic and physiological relationships between the individual microbes and within their communities can be studied and better understood. The methodology developed for molecular identification and physiological studies and recent results are reviewed. Strategies to generate biogas from unconventional substrates such as proteins, lignocelluloses and algae are discussed read more ...
