Process-resolved effects of dibutyl phthalate on sludge anaerobic fermentation: Enzyme inhibition and metabolic disruption underlie the suppression of acidogenesis.
Growing evidence suggests that leaching of plasticizers such as dibutyl phthalate (DBP) from microplastics inhibits methanogenesis in anaerobic digesters treating waste activated sludge. However, how DBP influences upstream anaerobic fermentation (AF) remains unclear. This study evaluated the effects of DBP on overall...
