Objective. A review of the degradation aspects of organic matter, obtaining energy and nutrients from anaerobic bacteria is performed. The importance of these organisms is the role they play in the processes contributing to the maintenance of life itself. Within the metabolism for the decomposition of macromolecules, these microorganisms perform several processes: hydrolysis acetogenesis and methanogenesis, among others, it covers reactions performed depending on the particular characteristics of the bacteria and of the roles in the degradative cycle for development of new products depending on the biochemical pathways or fermentation processes that take place there.

Keywords : anaerobic bacteria; biochemical pathways; hydrolysis; acetogenesis; methanogenesis.
