Acidogenesis is a key step in the anaerobic biotransformation of organic micropollutants [PDF]

open access: yesJournal of Hazardous Materials, 2020
Understanding the role of the different anaerobic digestion stages on the removal of organic micropollutants (OMPs) is essential to mitigate their release from wastewater treatment plants. This study assessed the fate of 21 OMPs during hydrolysis and acidogenesis to elucidate the contribution of these stages to the overall anaerobic removal.

Tequila vinasses acidogenesis in a UASB reactor with Clostridium predominance [PDF]

open access: yesSpringerPlus, 2015
Tequila vinasses represent an acidic, highly concentrated pollutant effluent generated during the distillation step of Tequila production. Although acidogenesis of Tequila vinasses has been reported for some reactor configurations, a characterization of the bacteria present during this metabolic process is lacking in the literature.
