Microorganisms are ubiquitous in the environment and are fundamental to the biogeochemical cycling of nutrients in marine, freshwater and terrestrial ecosystems. In the deep biosphere, microbial mediated transformations are responsible for shaping our natural resources over geological time. However, for many years our knowledge and understanding of microrogansisms in sub-surface environments, like oil reservoirs has been based primarily on culture-based approaches such as plate counts or most probable numbers (MPN).
