Factors restricting growth of heterotrophic bacteria in the water body of West Lake, Hangzhou

Abstract

Abstract: Restricting factors of bacteria growth were studied by pure culture and natural culture test. The results showed that organic carbon source available for bacteria was more important than (NH₄)₂SO₄ and KH₂PO₄, while higher pH, and rich biomass of phytoplanktons and zooplanktons in the water restrained the growth of heterotrophic bacteria. Under natural culture experiment, Azotobacter increased after 0.5% glucose was added, and a lot of mildew grew after adding0.5% glucose with 0.1%(NH₄)₂SO₄ and 0.1% KH₂PO₄, while Pseudomonas enriched 30～57% after adding0.01% beef extract. It was also showed that bacteria growth potentiality in natural water could reach to 10⁵cfu·ml^-1.
