Microbial ecology examines the diversity and activity of micro-organisms in Earth's biosphere. In the last 20 years, the application of genomics tools have revolutionized microbial ecological studies and drastically expanded our view on the previousl ...

Biological communities are remarkable in their ability to form cooperative ensembles that lead to coexistence through various types of niche partitioning, usually intimately tied to spatial structure. This is especially true in microbial settings whe ...

The diversity of purple and green sulfur bacteria in the multilayered sediments of the Ebro Delta was investigated. Specific oligonucleotide primers for these groups were used for the selective amplification of 16S rRNA gene sequences. Subsequently, ...

Soil bacterial communities were analyzed in different habitats (bulk soil, rhizosphere, rhizoplane) of poplar tree microcosms (Populus tremulaxP. alba) using cultivation-independent methods. The roots of poplar trees regularly experience flooded and ...

AIMS: To identify and compare the relative diversity and distribution of genotypes of culturable fluorescent pseudomonads from soils. METHODS AND RESULTS: Analysis of 160 isolates from seven soil samples using randomly amplified polymorphism DNA meth ...

AIMS: To examine bacterial contamination of passenger aircraft and to identify aeroplane environments posing the greatest potential health risk. METHODS AND RESULTS: DNA was extracted from ten environmental samples collected on four different flights ...

AIMS: The aim of this work was to measure the dynamic global metabolic activities of the microbial community during ripening of RDO Salers cheese by using a direct molecular approach. METHODS AND RESULTS: A culture-independent approach including PCR, ...

Phylogenetic and statistical analyses of 16S rRNA gene libraries were used for the investigation of actinobacterial communities present in two tropical estuarine sediments (Santos-São Vicente estuary, Brazil). The libraries were constructe ...

Many prokaryotes have multiple ribosomal RNA operons. Generally, sequence differences between small subunit (SSU) rRNA genes are minor (<1%) and cause little concern for phylogenetic inference or environmental diversity studies. For Halobacteriale ...

Soil samples collected from two hot springs, Soldhar and Ringigad, both located in the Garhwal region of Uttaranchal Himalaya were analysed for their physical, chemical and microbial components. The alkaline pH, total absence of carbon and nitrogen, ...
