Geomicrobiology of high-level nuclear waste-contaminated vadose sediments at the Hanford site, Washington State
Article Abstract:
The sediments from the high-level nuclear waste plume were accumulated as a component for checking to analyze the probability of a chance and the movement of the contaminants in the subsurface. The outcome indicated that the gram-positive bacteria, mainly from phyla high in G+C content are native to Hanford vadose sediments and a few of them have the capability to withstand very high chemical and physical stress in relation to the radioactive waste.

Enumeration and characterization of iron(III)-reducing microbial communities from acidic subsurface sediments contaminated with uranium(VI)
Article Abstract:
A combination of cultivation-based and cultivation independent approaches to characterize Fe(III)-reducing bacterial consortia from acidic subsurface sediments are used. Results indicate that the abundance/community composition of Fe(III) reducing consortia in subsurface sediments is dependent upon geochemical parameters or spore like bodies that were representatives of acidic subsurface environments.

Quantification of ammonia-oxidizing bacteria and factors controlling nitrification in salt marsh sediments
Article Abstract:
The range of salt marsh environments, which varied in their physicochemical characteristics, vegetation coverage, and macrofaunal abundance and the effects of Fe(III) and sulfide on nitrification are studied. The macrofaunal burrowing and high concentrations of Fe(III) stimulate nitrification may increase nitrogen removal through coupled nitrification-denitrification in salt marsh sediments.
