Environmental Microbiology - From Genomes to Biogeochemistry

Over the past 20 years, environmental microbiology has grown from relative obscurity into a vibrant area of both pure and applied science. Environmental microbiology is inherently multidisciplinaryrelying upon contributions from analytical chemistry, geosciences, environmental engineering, public health, ecology, evolution, and microbiology.
