We examined sediments collected at Ocean Drilling Program (ODP) Leg 201 Site 1229 on the Peru Margin for microbial populations throughout the sediment column. Heterotrophic cultivation from these sediments yielded numerous colonies from various depths, including 49 bacterial isolates. At ODP Site 1229, there are significant interfaces of sulfate and methane, across which microbial cell numbers increase substantially. At these sulfate/ methane transition zones (SMTZs), however, we observed a… CONTINUE READING
