Abstract:

Three habitats local to Durham were selected for this work Mill Pond, a freshwater eutrophic pond draining Oyster River into Great Bay estuary, the estuary, and a marine coastal saltmarsh in which we have found large populations of sulfide-type magnetic bacteria. Data being sought will enable the first systematic comparison among marine, estuarine and freshwater habitats of seasonal and vertical distribution of natural populations of magnetotactic bacteria. Enrichments and pure cultures of faculative and obligate iron-reducing bacteria from these diverse environments have been made and are still in progress. To date, new strains of iron reducing bacteria, some of which may be magnetogenic, have been isolated but these have not been characterized.
