 note = {The ecological distribution of microorganisms in the water body of West Lake was studied from April 1995 to April 1996. Results showed that the average density of heterotrophic bacteria was 2.06x10³/ml. Actinomycetes, molds and yeast had already of 35/ml, 24/ml and 2/ml, respectively. Various physiological forms of microbes were found in West Lake, including cellulose decomposing bacteria (25/ml), organic phosphorus decomposing bacteria (8/ml), and Nitrogen utilizing bacteria such as nitrite bacteria (453/ml), nitrate bacteria (585/ml), nitrate-reducers (3.2x10³/ml), and denitrifiers (43/ml). Contrasting to nitrate bacteria, cellulose decomposing bacteria, ammonifiers, nitrite bacteria and nitrate reducers were rich in winter and spring. Autotrophic bacteria, like nitrifiers were more common in L. Xiaonan and L. Beili, where the water quality was relatively good, Heterotrophic bacteria were populous in the two highly eutrophic lakes (L.Yuehu and L. Xili). The study on 78 strains isolated randomly from the five sub lakes suggested that the dominant groups in West Lake were Pseudomonas, Bacillus and Enterobacteriaceae., Article, 信州大学理学部附属諏訪臨湖実験所報告 11: 51-57(1999)},
