Brief Description (Abstract):

Bacterial diversity from Schirmacher Oasis, Antarctica was assessed by 16S rDNA clone library analysis. The samples were collected from sites with obvious human impact and sites with low or non-obvious human impact during the austral summer of 2004/2005, winter of 2005 and austral summer of 2005/2006. Analysis of clones from high human impact sites showed higher bacterial diversity in comparison with clones from the pristine sites. About 74 different unique phylotypes have been identified. Most of the sequenced clones are related to the phyla ¿Proteobacteria, a-Proteobacteria, ß-Proteobacteria, Actinobacteria, and Bacteroidetes. Pseudomonas sp. from the ¿-Proteobacteria phylum was the most dominant species found in the Schirmacher Oasis, occurring in the high as well as low impact sites. Bacterial community profiles from three consecutive seasons were analysed by denaturing gradient gel electrophoresis (DGGE).

Status: Completed

Purpose: This study incorporated both 16S rDNA clone library and PCR- DGGE to assess the bacterial diversity of environmental samples from Schirmacher Oasis. PCRDGGE analysis was used to compare the environmental samples from three consecutive seasons from Schirmacher Oasis.
