Microbial communities in the saturated groundwater environment I: Methods of isolation and characterization of heterotrophic bacteria.

abstract：:Simulation modeling has been an integral, albeit ad hoc, component of the field of aquatic microbial ecology for the past two decades. One of the most critical steps in simulation modeling is the initial formulation of a clear set of questions and goals. It is doubtful that a single generic model could be constructed ...
