The microbiology of caves is an important topic for better understanding subsurface biosphere diversity. The diversity and taxonomic composition of bacterial communities associated with cave walls of the Oylat Cave was studied first time by molecular cloning basedon Sanger/pyrosequencing approach. Results showed an average of 1,822 operational taxonomic units per sample. Clones analyzed from Oylat Cave were found to belong to 10 common phyla within the domain Bacteria. Proteobacteria dominated

Similarly, the principle of homophily has prominence in much of the theory surrounding social network scholarship (McPherson and Smith-Lovin, 1987; McPherson et al., 2001). However, recent scholarship has highlighted the strength of cognitively diverse teams for problem solving and decision making (Page, 2007). Through a diversity of perspectives, interpretations

Consequently, the diversity study of endophytic bacteria in G. littoralis will clarify the interactions between endophytic bacteria and salt tolerance of G. littoralis.
The present research’s main idea was to gain a broad general view of the endophytic bacterial community in different tissues of G

Quite recently, a new putative species, BVDV-3, was detected. The viruses exist as one of two biotypes: cytopathic or non-cytopathic, based on their activity in cell

A method for performing long PCR using single nematodes and sequencing nematode mitochondrial genomes individually is presented here. About 8 kb (∼55%) of the complete mitochondrial genome was successfully obtained from 285 individuals collected from 12 populations. The 158 single nucleotide polymorphisms detected corresponded to 30 haplotypes

Paeonia ostii is known for its excellent medicinal values as Chinese traditional plant. To date, the diversity of culturable endophytes associated with P. ostii is in its initial phase of exploration. In this study, 56 endophytic bacteria and 51 endophytic fungi were isolated from P. ostii roots in China. Subsequent characterization of 56 bacterial strains by 16S rDNA gene sequence analysis revealed that nine families and 13 different genera were represented. All the fungal strains

Fruits constitute excellent habitats for yeasts, mainly due to their low pH, availability of nutrients, and active fruit-associated vectors. These traits are variable across the type and maturity of the fruit. Changes in the community in response to varying availability of nutrients, production of mycotoxins, and the arrival of new yeast species are evident (Tournas and Katsoudas 2005; Starmer and Lachance 2011).

There are a variety of resources relevant for doing science. We can roughly divide them into two categories: (1) resources which are directly engaged in collaboration such as expertise in a particular research topic or a research method, and (2) resources of a more “social” kind, e.g. contacts in academia or

The nucleotide sequences of their inserts suggest that bacteria present in the mine environment belong to: Flavobacteria, Sphingobacteriia, Bacteroides, Proteobacteria, Mollicutes and Firmicutes. The metagenomic approach allows to demonstrate a higher diversity of microbiota than classical microbiological studies of cultivable isolates.
