An algicidal bacterium was isolated from Lake Taihu during the bloom of Microcystis in 2009. It was Gram-negative, oxidase-negative, and produced red-colored colonies on agar media. The strain was tentatively identified as Serratia marcescens by means of physiological, biochemical reactions and homology analysis based on 16S rDNA. The bacteria could degrade Microcystis aeruginosa effectively. When...
In this paper, a new stochastic model based on cellular automata is established to simulate the occurrence and development of Schistosoma japonicum (S. japonicum) infection in an endemic population. We included the process of the pathogen invasion from exposure to worm development and till worm death when the infection is cleared in the model. We further utilized the model to predict the prevalence...
Study on microbial community structure and diversity in freshwater is important for exploiting the relationship of microbial community and its habitats, predicting and monitoring the ecological changing of contaminated water habitat. The retrieval of 16SrDNA genes directly from the environment has made it possible to estimate the phylogenetic diversity of a natural bacterial community without preceding...
