| Abstract: | Diver collected cores from three sites in Lake Erie, west of Cleveland, Eastern basin and near Buffalo, and one from Lake Ontario near the mouth of the Niagara River, were sectioned to 20 cm and examined for sulfur cycle and nitrogen cycle bacteria, heterotrophic bacteria, insoluble organic and inorganic phosphate solubilizing bacteria and manganese oxidizing bacteria. Eh, pH, nitrogen, organic carbon and percentage moisture determinations were also made. Data from this study support and confirm other microbiological data collected from Lower Great Lakes sediment and also support the hypothesis that microbial flora of similar type sediments are numerically similar irrespective of the sediments source within the Lower Great Lakes. |
