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.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráAguas residuales industrialesTratamiento de aguas residualesIndustria alimenticiaDigestión anaerobiaArticle
