---- Public Summary from Project ----
This project aims to determine bacterial diversity in Antarctica, including non-culturable strains, by the use of various techniques. Soil, sediment and water samples will be collected from different sites e.g. relatively pristine sites, sites impacted by ... human activities, penquin rookeries. Isolation of bacteria from these samples will be carried out and isolates will be screened for special traits such as biodegradation of persistent organic pollutants (POP) or synthesis of biopolymers. Positive isolates will be compared with tropical bacteria isolates having similar abilities.
Samples were collected from two Sites of Special Scientific Interest in the Casey area. These were SSSI 16 and SSSI 17. Samples were also collected from around Casey Station. SSSI 16 and SSSI 17 are now known as Antarctic Specially Protected Areas. The new designation for SSSI 16 and 17 respectively is ASPA 135 and ASPA 136.
The following work was completed as part of this project:
1) Obtained some bacteria isolates from antarctic soil and sediment, using common and selective microbiological media.
2) From the micropore membranes, we extracted genomic DNA, PCR the 16S rRNA gene, cloned and sequence the gene to determine bacterial species.
Water samples were filtered through micropore membranes to concentrate bacteria.
The download file contains data on bacterial diversity in meltlake water and sediment from two sites around Casey station, ASPA 135 and ASPA 136.
