产酸相稳定发酵类型微生物生态学研究

Study on Microbiological Ecology of Steady Fermentation in Acidogenic Phase

通过产酸发酵反应器的动态试验 ,考察生态因子 (pH、ORP)等制约的不同发酵类型顶极群落的结构、优势种群的组成和生态演替的规律 ,阐明不同发酵类型代谢及其顶极群落的典型特征 ,揭示产酸发酵过程中顶极群落内平衡与反馈调节的生理代谢机制 ,并以 pH值。

A continuous-flow fermentation reactor in bench scale was used to study the structure and dominant composition, as well as ecological succession of climax community restricted by factors such as pH, ORP. In this paper, typical characteristics of metabolization of different fermentation and relevant climax community was enunciated. Physiological metabolic mechanism of internal balance and the feedback adjusting mechanism of the climax community was described. In addition, a figure of ecological niche with pH /ORP as coordinate during the course of ecological succession was presented.
