title = "Control of fermentation types in continuous-flow acidogenic reactors: Effects of pH and ORP",
abstract = "An experiment was carried out in continuous-flow acidogenic reactors and molasses was used as substrate to study the effects of pH and redox potential on fermentation types and the control. In the different experimental stages of start-up, pH-regulating and redox potential-regulating, the conditions and transformed process for each fermentation type were investigated. The experiments confirmed that butyric acid-type fermentation would occur at pH>6, the propionic acid-type fermentation at pH about 5.5 with Eh> -278 mV, and the ethanol-type fermentation at pH<4.5. A higher redox potential will lead to propionic acid-type fermentation because propionogens are facultative anaerobic bacteria. It was also demonstrated that the representative strains of ethanol-type, butyric acid-type and propionic acid-type climax community are Bacteroides, Clostridium and Propionibacterium respectively for the acidogenic fermentation of wastewater.",
