A 5 yr field experiment was carried out comparing the effects of Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W40), used synthetic lubricant (used Mobil 0W40) and a biodegradable lubricant (Titan GT1) on Antarctic benthic microbial communities.
In 2001 a unique field experiment was established to compare the longevity and effects of four different oils on the Antarctic benthic ecosystem. Clean sediment was collected, spiked with one of the oils: Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W-40)…
The sea ice microbial community plays a key role in the productivity of the Southern Ocean. Exopolysaccharide … (EPS) is a major component of the exopolymer secreted by many marine bacteria to enhance survival … and is abundant in sea ice brine channels, but little is known about its function there.
Exopolysaccharides (EPSs) are high molecular weight … carbohydrate polymers that make up a substantial … component of the extracellular polymers surrounding … most microbial cells in the marine environment.
Aims: This study was undertaken to examine and characterize Antarctic marine bacterial isolates and the … exopolysaccharides (EPS) they produce in laboratory culture. Methods and Results:
Exopolysaccharides (EPS) may have an important role in … the Antarctic marine environment, possibly acting as ligands … for trace metal nutrients such as iron or providing … cryoprotection for growth at low temperature and high … salinity. Ten bacterial strains…
Australia’s Antarctic territory contains several hydrocarbon-contaminated sites of varying size and severity as a result of fifty years of human activities in the region. Contaminated site remediation in Antarctica is more challenging than in Australia.
A real-time polymerase chain reaction (PCR) method to … quantify the proportion of microorganisms containing … alkane monooxygenase was developed and used to follow … changes in the microbial community in hydrocarboncontaminated … Antarctic soil during a bioremediation field … trial.
Micro-organisms are an important part of the Antarctic ecosystem contributing to the biogeochemical cycling of nutrients.
Abstract A microbial enrichment culture tolerant of … petroleum hydrocarbons was developed from sediment … collected near Casey Station, Antarctica. To select coldadapted … microbes that would degrade diesel, enrichments … were cultured at 0°C during six successive … transfers to fresh medium…
The effects of diesel fuel and three lubricating oils on microbial communities in marine sediment were investigated in a field experiment at Casey Station, Antarctica. Sediment from a pristine site in Antarctica was treated with either Special Antarctic Blend (SAB) diesel, a synthetic lubricant…
The collapse of the Larsen A and B and other ice shelves fringing the Antarctic Peninsula … coastline raises questions about the status of ice shelves in other parts of the continent. Are … the large ice shelves along the East Antarctic coast also in danger of permanent collapse…
