Anaerobic synecology of the hydrogen-producing fermentation system was investigated under certain test condition in this thesis. In the continuous flow system of anaerobic hydrogen-producing fermentation, the succession of hydrogen-producing acidogenic microbiology may be regressive process. By regressive process we means that the original community getting from nature which structure being complex with a high ability would degenerate gently to a certain climax community which structure being simple with less ability.

产氢发酵系统的微生物群落生态学研究证明，在连续流发酵产氢反应系统中产氢产酸发酵细菌群落的演替过程，是在人为控制的生境条件下，微生物从自然群落这种稳定性大、组成及生化反应过程复杂的生态群落，向稳定性小、组成和生化反应过程相对简单的某一产酸发酵顶极群落进行的"逆行演替"。

Methods Two arrays of isolates were used to evaluate the reliability of ChromID ESBL. One array contained 285 clinical isolates in which the ESBLs-producing feature was screened by confirmatory tests recommended by Clinical and laboratory Standards Institute. The other array contained 28 enterobacterial isolates with their ESBLs gene and producing enzyme feature being confirmed previously.

用2组肠杆菌科细菌进行评估，一组为285株上海地区检出的临床分离株，这些菌株已用美国临床实验室标准化研究所推荐的确证试验确认了是否产ESBLs，另一组28株产ESBLS肠杆菌科细菌，在以前的研究工作中已确认了这些菌株的产酶特性和ESBLs。
