Publikováno v: Applied and Environmental Microbiology. 81:4164-4172

A pilot-scale field experiment demonstrated that a one-time amendment of emulsified vegetable oil (EVO) reduced groundwater U(VI) concentrations for 1 year in a fast-flowing aquifer. However, little is known about how EVO amendment stimulates the fun

Massively parallel rRNA gene sequencing exacerbates the potential for biased community diversity comparisons due to variable library sizes

Autor: Christopher W. Schadt, Thomas M. Gihring, Stefan J. Green

Publikováno v: Environmental Microbiology. 14:285-290

Technologies for massively parallel sequencing are revolutionizing microbial ecology and are vastly increasing the scale of ribosomal RNA (rRNA) gene studies. Although pyrosequencing has increased the breadth and depth of possible rRNA gene sampling,

A Limited Microbial Consortium Is Responsible for Extended Bioreduction of Uranium in a Contaminated Aquifer

Autor: Susan L. Carroll, Wei-Min Wu, Zamin Yang, Craig S. Criddle, David B. Watson, Stefan J. Green, Kenneth A. Lowe, Thomas M. Gihring, Gengxin Zhang, Craig C. Brandt, Christopher W. Schadt, Tonia L. Mehlhorn, Phil Jardine, Scott C. Brooks, James H. Campbell, Joel E. Kostka, Will A. Overholt

Publikováno v: Applied and Environmental Microbiology. 77:5955-5965

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 sustained uranium bioimmobilization within contaminated groundwater systems.

Publikováno v: Geomicrobiology Journal. 28:275-300

The diversity of planktonic microorganisms in fluids from a group of flowing subterranean boreholes was monitored from the day they were drilled to as long as three and a half months after drilling as they drained into Evander Au mine. Geochemical an

Publikováno v: Applied and Environmental Microbiology. 76:3244-3254

In terrestrial subsurface environments where nitrate is a critical groundwater contaminant, few cultivated representatives are available to verify the metabolism of organisms that catalyze denitrification. In this study, five species of denitrifying
