Evidence of Extensive DNA Transfer between Bacteroidales Species within the Human Gut [PDF]

open access: yes, 2014
The genome sequences of intestinal Bacteroidales strains reveal evidence of extensive horizontal gene transfer. In vitro studies of Bacteroides and other bacteria have addressed mechanisms of conjugative transfer and some phenotypic outcomes of these DNA

Ectothiorhodospira variabilis, sp. nov., an alkaliphilic and halophilic purple sulfur bacterium from soda lakes [PDF]

open access: yes, 2009
During studies of moderately halophilic strains of Ectothiorhodospira from steppe soda lakes, we found a novel group of bacteria related to Ectothiorhodospira haloalkaliphila with salt optima at 50–80 g NaCl l”1. Phylogenetic analysis using 16S rRNA gene

Characterization and Screening of N(2)-fixing Microorganisms at Maturity Stage in Rhizosphere of Rice Grown in Brahmaputra Alluvium Soil of Bangladesh [PDF]

open access: yes, 2007
Studies on the existing non-symbiotic diazotrophic systems still are the most promising for better use of biological nitrogen fixation (BNF) in agriculture. The possibilities for the extension of nitrogen fixation to rice plants still speculative.

Ecology and application of haloalkaliphilic anaerobic microbial communities [PDF]

open access: yes, 2015
Haloalkaliphilic microorganisms that grow optimally at high-pH and high-salinity conditions can be found in natural environments such as soda lakes. These globally spread lakes harbour interesting anaerobic microorganisms that have the potential of being

Microbial hitchhikers on intercontinental dust: high-throughput sequencing to catalogue microbes in small sand samples [PDF]

open access: yes, 2018
Microbiological studies on the intercontinental transport of dust are confounded by the difficulty of obtaining sufficient material for analysis. Axenic samples of dust collected at high altitudes or historic specimens in museums are often so small and ...
