Influence of particle size on bacterial community structure in aquatic sediments as revealed by 16S rRNA gene sequence analysis.
نویسندگان
چکیده
Bacterial communities associated with sediment particles were examined using PCR-denaturing gradient gel electrophoresis and 16S rRNA gene sequencing. Particle size influenced community structure, with attached bacterial assemblages separating into 63- to 125-, 125- to 1,000-, and 1,000- to 2,000-microm fractions. Differences were particularly pronounced for the Verrucomicrobia-Planctomycetes, whose numbers were significantly reduced on coarser particles.

Genetic variations of avian Pasteurella multocida as demonstrated by 16S-23S rRNA gene sequences comparison
Pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. A polymerase chain reaction (PCR) assay was developed using primers derived from conserved part of 16S-23S rRNA gene. The PCR amplified a fragment size of 0.7 kb using DNA from nine avian P. multocida isolates...

Introduction: Mycoplasmas are one of the most serious contaminants of cellular cultures and their biological productions. Mycoplasma diagnosis is conducted on the basis of culture and molecular methods. These methods are different from each other in terms of accuracy, reliability, and sensitivity. This study aimed to trace the mycoplasma contaminations in culture samples using 16S rRNA specific...

BACKGROUND A geothermal ecosystem located at Tantloi, India has been found to be an interesting habitat for microbes of diverse nature. However, the microbial diversity of this habitat is poorly explored. In this study, a detailed phylogenetic study has been carried out to understand the bacterial diversity of this habitat and to identify prospective metal reducers using culture independent app...
متن کاملNitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage
Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms and in mitigating nitrogen pollution. We evaluated the gene abundance and diversity of nitrifying microbes in AMD-impacted sediments: ammonia-ox...
