Proteomics of psychrotolerant Trichococcus patagoniensis and characterization of the produced exopolysaccharides as inulin

The psychrotolerant Trichococcus patagoniensis was previously reported to produce exopolysaccharides (EPS) that covers the cells, when grown at a low temperature. Although, T. patagoniensis has an optimal growth at 30 ºC, it still can grow at -5 ºC. This capability of T. patagoniensis to grow at subzero temperatures is expected to be reflected in the proteome, membrane lipid composition and/or EPS production. This study aimed to get insight into the cold adaptation mechanisms of T. patagoniensis. We compared the proteomes of cells grown at 0 and 30 ºC and the EPS that is formed.
