Over the last several years, the work in Krumholz's laboratory has focused on the study of sulfate reducing bacteria. These microorganisms are important for microbial processes occurring in oxygen depleted (anaerobic) environments. Most experiments have utilized microorganisms from subsurface (aquifer) sediments but others have included bacteria from freshwater and marine sediments. These studies have focused the physiology of these organisms, on their roles in anaerobic ecosystems and on the potential of these microorganisms to carry out bioremediation processes. Approaches have taken several angles, with molecular studies, pure culture physiological and biochemical studies as well as studies with intact sediments. This breadth has allowed us to address questions ranging from very basic to very applied.
