Fingerprinting microbial assemblages from the oxic/anoxic chemocline of the Black Sea

Article Abstract:

Biomass samples from the Black Sea were analyzed for SSU genes from Bacteria and Archaea after ten years of storage at -80 degrees Celsius and both clonal libraries and fingerprinting by terminal restriction fragment length polymorphism analyses were used to assess the microbial community. Of the clones obtained, an epsilon-Proteobacteria and a Pseudoalteromonas-like clone accounted for major peaks in the fingerprint, while deeply branching lineages were associated with smaller peaks.

Variation in 16S-23S rRNA intergenic spacer regions in Photobacterium damselae: A mosaic-like structure

Article Abstract:

A study is conducted where the nucleotide sequences of internal transcribed spacers (ITS) of strains belonging to the two subspecies of Photobacterium damselae were analyzed. However, no specific sequences exist in either of the subspecies, which strongly suggests that recombination and concerted evolution are responsible for the exchange of nucleotide blocks.

Allelic diversity and population structure in Oenococcus oeni as determined from sequence analysis of housekeeping genes

Article Abstract:

The genetic diversity and genetic relationships among Oenococcus oeni strains is determine with the help of multilocus sequence typing (MLST) with the gyrB, pgm, ddl, recP and mleA genes. The findings indicate that recombination plays a major role in creating the genetic heterogeneity of O. oeni.
