Anaerobic fermentation, which is common to all bacteria and eukaryotes, is a metabolic process that converse carbohydrates (sugar) to organic acids, gases or alcohols under anaerobic conditions. Therefore, microorganisms are used to produce nutraceuticals or bacteriocins through accumulation of various primary metabolites, as well as complex secondary metabolites. Metabolic engineering strategies are usually involved so that the production of a certain metabolite can be emphasized or...
