摘要: The effect of pH (4.0, 5.0, and 6.0) on acidification fermentation fruit vegetable wastes was investigated using batch semi-continuous experiments under mesophilic condition. Results showed that types change with variation. system containing could automatically decrease to 3.0 ~ 4.0. At this range, a stable ethanol production observed, at which ethanol-type obtained. Based the results, were classified into ethanol-type, mixed acid-type, propionic butyric acid-type fermentations, occurred 4.0 4.5, 4.5 5.0 5.5, 5.5 6.5, respectively.
