汾河(太原市景区段)微囊藻的分子多样性及产毒能力
Molecular diversity and microcystin production of Microcystis in Fenhe River of Taiyuan
摘要
Abstract
To study the molecular diversity of Microcystis in Fenhe River of Taiyuan, phylogenetic analyses based on ITS、PC-IGS and gyrB genes were performed from 7 isolated strains of Microcystis. These seven Microcystis strains formed distinct lineages, suggesting high diversity of Microcystis. ELISA and whole-cell PCR targeting microcystin synthetase gene (mcyA) were used to determine microcystin production. Results showed that six of the seven strains contain mcyA gene and the microcystin concentrations of the six Microcystis strains ranged from 0.003mg/g to 0.043mg/g. This is the first report of toxic Microcystis in Fenhe River, and it is urgent that more critical measures should be taken for the protection of Fenhe River.关键词
