[Community structure characteristics of phytoplankton and related affecting factors in Hengshan Reservoir, Zhejiang, China].

In order to reveal the community structure characteristics of phytoplankton and the relationships with environmental factors in Hengshan Reservoir, the phytoplankton species composition, abundance, biomass and 12 environmental factors at 4 sampling sites were analyzed from March 2011 to February 2012. A total of 246 phytoplankton species were identified, which belong to 78 genera and 7 phyla. The dominant species were Melosira varians, M.

[Fluorescence quench of bovine serum albumin by pentachlorophenol].

The interaction between pentachlorophenol and bovine serum albumin (BSA) were studied using fluorescence spectra and ultraviolet-visible light absorption spectra. The results show that the fluorescence of BSA was quenched regularly by the pentachlorophenol, the mechanism of the fluorescence quench was investigated. The binding constants and thermodynamic parameters of pentachlorophenol with BSA were obtained at different temperatures.
