Bacterial community structure and diversity in a century-old manure-treated agroecosystem
(American Society for Microbiology, 2004-10)
Changes in soil microbial community structure and diversity may reflect environmental impact. We examined 16S rRNA gene fingerprints of bacterial communities in six agroecosystems by PCR amplification and denaturing gradient ...
Novel high-rank phylogenetic lineages within a sulfur spring (Zodletone Spring, Oklahoma), revealed using a combined pyrosequencing-Sanger approach
(American Society for Microbiology, 2012-04-15)
The utilization of high-throughput sequencing technologies in 16S rRNA gene-based diversity surveys has indicated that within most ecosystems, a significant fraction of the community could not be assigned to known microbial ...
Novelty and uniqueness patterns of rare members of the soil biosphere
(American Society for Microbiology, 2008-09)
Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed ...
Microbial community structure in petroleum-contaminated sediments corresponds to geophysical signatures
(American Society for Microbiology, 2007-05)
The interdependence between geoelectrical signatures at underground petroleum plumes and the structures of subsurface microbial communities was investigated. For sediments contaminated with light non-aqueous-phase liquids, ...
Influence of the drilling mud formulation process on the bacterial communities in thermogenic natural gas wells of the Barnett Shale
(American Society for Microbiology, 2011-07)
The Barnett Shale in north central Texas contains natural gas generated by high temperatures (120 to 150°C) during the Mississippian Period (300 to 350 million years ago). In spite of the thermogenic origin of this gas, ...
Rumen microbial population dynamics during adaptation to a high-grain diet
(American Society for Microbiology, 2010-11)
High-grain adaptation programs are widely used with feedlot cattle to balance enhanced growth performance against the risk of acidosis. This adaptation to a high-grain diet from a high-forage diet is known to change the ...
Assessment of the diversity, abundance, and ecological distribution of members of candidate division SR1 reveals a high level of phylogenetic diversity but limited morphotypic diversity
(American Society for Microbiology, 2009-06)
We used a combination of 16S rRNA gene clone library surveys, quantitative PCR (qPCR) analysis, and fluorescent in situ hybridization to investigate the diversity, abundance, and distribution of members of candidate division ...
