Effect of Different Carbon Sources on Biosynthesis of Exopolysaccharide from Antarctic StrainCryptococcus LaurentiiAL₆₂

“…Carbohydrates content in the purifi ed fractions was 98.2% for fraction I, and 87.3% for fraction II (Pavlova et al, 2005). The yeasts that produce heterogeneous polymers in the same culture also include Candida laurentii CCY 17-3-16 (Breierová et al, 2005) and Candida laurentii AL 62 (Rusinova-Videva et al, 2011).…”

“…The sources of carbon are monosaccharides in the form of pentoses, hexoses, as well as disaccharides and trioses. Yeasts produce varying amounts of EPS in media containing, among others, glucose, sucrose, xylose, ribose, arabinose, galactose, mannose, rhamnose, raffi nose, trehalose (Pavlova et al, 2004;Rusinova-Videva et al, 2011). Sucrose is considered the most optimum carbon source for EPS production for the majority of producer strains.…”

“…In the view of clinical trials, this polysaccharide heparinase inhibitor exhibits an antitumor activity (Rusinova-Videva et al, 2011). Chemical structure of exopolysaccharide synthesized by P. holstii NRRL Y-2448 was investigated and described (Parolis et al, 1998).…”

“…Yeast inhabiting the cold ecosystems have focused an interest, not only due to their metabolic adaptation to extreme environmental conditions, but also the possibility of valuable substances obtaining, like discussed herein exopolysaccharides, and enzymes, lipids or carotenoids (Rusinova-Videva et al, 2011;Turkiewicz, 2006).…”

“…The yeast strains isolated from penguin feathers and Arctic soil (Pavlova et al, 2004;, as well as lichens and mosses (Pavlova et al, 2004;Rusinova-Videva et al, 2011), were examined towards the ability of extracellular polysaccharides production. The isolated psychrophilic strains, capable of large quantities of EPS production, belong to Sporobolomyces, Cryptococcus, Debaryomyces, Rhodotorula and Pseudozyma genera.…”
