Seasonal Variations in Microbial Populations and Environmental Conditions in an Extreme Acid Mine Drainage Environment
ABSTRACT Microbial populations, their distributions, and their aquatic environments were studied over a year (1997) at an acid mine drainage (AMD) site at Iron Mountain, Calif. Populations wereExpand

Arsenite oxidation and arsenate respiration by a new Thermus isolate.
A new microbial strain was isolated from an arsenic-rich terrestrial geothermal environment. The isolate, designated HR13, was identified as a Thermus species based on 16S rDNA phylogeneticExpand

A Limited Microbial Consortium Is Responsible for Extended Bioreduction of Uranium in a Contaminated Aquifer †
ABSTRACT Subsurface amendments of slow-release substrates (e.g., emulsified vegetable oil [EVO]) are thought to be a pragmatic alternative to using short-lived, labile substrates for sustainedExpand
