Abstract: The populations of sulfate-reducing bacteria in Lake Fryxell, both 16 rRNA gene and metabolic primer sets targeting the dsrA gene for the dissimilatory sulfite reductase alpha subunit were employed to analyze environmental DNA obtained from the water column and sediments of Lake Fryxell were investigated. Several clone groups were highly localized with respect to lake depth and therefore experienced specific physiochemical conditions.
