Brief description

Exopolysaccharide (EPS) is complex sugar made by many microbes in the Antarctic marine environment. This project seeks to understand the ecological role of microbial EPS in the Southern Ocean, where it is known to strongly influence primary production. We will investigate the chemical composition and structure of EPS obtained from Antarctic microbes, which will improve our knowledge of its ecological significance and biotechnological potential.

Dataset includes the following:

1) Information on Exopolysaccharide-producing bacterial isolates, isolation sites, media used and growth conditions.

2) 16S rRNA gene sequence and fatty acid data of isolates for strain identification.

3) Exopolysaccharide chemistry data including EPS carbohydrate composition, organic acid composition, sulfate content, molecular weight.

4) Physiology of exopolysaccharide synthesis. Effects of temperature and other factors on EPS yield and glucose conversion efficiency.

5) Iron binding properties.
