PARRA HUERTAS, Ricardo Adolfo. Anaerobic digestión: biotechnological mechanisms in waste water treatments and their application in food industry. Rev. P+L [online]. 2015, vol.10, n.2, pp.142-159. ISSN 1909-0455.

Anaerobic digestion (AD) is a biochemical process that consists on the degradation of organic matter from waste water. AD has four stages: Hydrolysis, acidogenesis and methanogenesis. Hydrolitic microorganisms intervene in each one, and clostridium, acetovibrio, micrococcus, staphylococcus and bacillus can be highlighted, along with acidogenics such as Acinetobacter Lwoffi, Acinetobacter sp, Actinomyces sp, Alcaligenes, Pasteurella sp, Staphylococcus hominis, Bacillus and Kleibsiella oxytoca, and methanogens like Methanosarcina and Methanosaeta. AD has a wide range of applications in food industries, especially in dairy, wine, meat, oils and brewery, among others.

Keywords : waste water; microorganisms; applications; food.
