Biogenic mineral production by a novel arsenic-metabolizing thermophilic bacterium from the Alvord basin, Oregon

Article Abstract:

The phylogenetic, physiological, and morphological characteristics of YeAs, an anaerobic, moderately thermophilic, arsenic-reducing bacterium is presented. It could have major implications in the search of innovative methods for arsenic waste management and novel biogenic mineral signatures.

Linked redox precipitation of sulfur and selenium under anaerobic conditions by sulfate-reducing bacterial biofilms

Article Abstract:

The precipitation of significant quantities of selenium and sulfur by sulfate-reducing bacteria (SRB), growing as attached biofilm under environmentally relevant conditions is reported. Precipitation occurred by an abiotic reaction with bacterially generated sulfide.

Comparison of the sensitivities of noroviruses and feline calicivirus to chemical disinfection under field-like conditions

Article Abstract:

The sensitivities of different noroviruses (NV) and feline calicivirus (FCV) to chemical disinfection under various field-like conditions are studied. The results prove that NV is much more resistant to infection, as compared to FCV.
