Acidogenesis

Overview of the anaerobic utilization of polymeric substrates and lipids

In addition to hydrolysis , acetogenesis and methanogenesis, acidogenesis represents a step in fermentation in an optional anaerobic degradation process. It takes place simultaneously with hydrolysis, and during this unspecific acid formation , the monomeric interducts of hydrolysis are converted into lower fatty / carboxylic acids , such as B. butyric , propionic and acetic acid , on the other hand in lower alcohols , such as. B. ethanol implemented. In this conversion step, the facultative anaerobic microorganisms record an energy gain for the first time and up to 20% of the total proportion of acetic acid is already formed during this conversion.
