Diversity of Geobacteraceae species inhabiting metal-polluted freshwater lake sediments ascertained by 16S rDNA analyses.

abstract：:Three dominant types of sugar-fermenting bacteria were isolated from the anaerobic, intertidal sediments of the Eems-Dollard estuary by applying techniques involving anaerobic agar shake tubes. One of the isolated types was tentatively identified as aStreptococcus species, the other two asBacteroides species. All type...
