Extracting DNA

Summer Student Fellow Erica Hildebrand of Connecticut College spent her summer working with WHOI biologist Stefan Sievert on a project to assess the microbial community composition of five distinct low-temperature (10ºC – 50ºC) diffuse flow deep-sea hydrothermal vents located on the East Pacific Rise at 9ºN. The vents have been repeatedly sampled over a period of 2 years subsequently to a volcanic eruption that occurred at this site in late 2005 to early 2006. Fluids were collected using a large volume pump to concentrate the microorganisms onto filters. Erica, shown here in Sievert’s Lab for Microbial Ecology and Physiology, is extracting DNA from some of the filters.
