摘  要：
对苏州地区金鸡湖与尚湖水体中的微生物数量及种群组成的研究表明,异养细菌数金鸡湖比尚湖高,分别为1.7～26万个/mL和500～80000个/mL,高峰期出现在10月份;放线菌和霉菌数量较少,金鸡湖为0～19个/mL和0～7个/mL,尚湖为1～25个/mL和0～37个/mL。从大肠菌群数看,金鸡湖明显高于尚湖,分别为350～16000个/L和20～250个/L,表明金鸡湖接纳生活污水和施肥养鱼对大肠菌群数的升高至关重要;金鸡湖和尚湖水体中分别检测出8个和9个属的异养细菌,优势菌分别为弧菌属、气单胞菌属、芽孢杆菌属和不动杆菌属、假单胞菌属、芽孢杆菌属。

摘  要：
Species and population of microorganisms in the water body of Jinji and Shang lakes had been investigated from June 1998 to October 1999. The results show that the amount of heterotrophic bacteria is 17000-260000/mL in the Jinji Lake, being higher than that in the Shang Lake(500-80000/mL) ,and its highest density appeares in October; densities of actinomyces and molds are lower, 0-19/mL, 0-7/mL in the Jinji Lake and l-25/mL,0-37/mL in the Shang Lake, respectively; amount of coliform is higher in the Jinji Lake than in the Shang Lake, 350 -16000/L and 20-250/L, respectively, suggesting that the enrollment of waste water and fertilizer application for fishing in the Jinji Lake have significant effect on the amount of coliform; 8 genera in the Jinji Lake and 9 genera in the Shang Lake have been found and the dominant groups are Vibrion, Aeromonas, Bacillus and Acinetobacter, Pseudomonas, Bacillus, respectively.
