Diversity and extracellular enzymatic activities of yeasts isolated from King George Island, the sub-Antarctic region

Abstract: BackgroundAntarctica has been successfully colonized by microorganisms despite presenting adverse conditions for life such as low temperatures, high solar radiation, low nutrient availability and dryness. Although these “cold-loving” microorganisms are recognized as primarily responsible for nutrient and organic matter recycling/mineralization, the yeasts, in particular, remain poorly characterized and understood. The aim of this work was to study the yeast microbiota in soil and water samples collected on Kin… Show more

“…victoriae, D. fristingensis, Leuconeurospora sp., Rh. larynges and W. anomalus (Carrasco et al 2012). Several yeasts and fungi isolates including Cryptococcus victoriae, Trichosporon pullulans and Geomyces pannorum, showed multiple enzymatic activities including lipase, cellulase and gelatinase, with higher activities at 4 and/or 20°C (Loperena et al 2012).…”

“…Chitinase activity was described in Antarctic yeast isolates D. fristingensis, Leuconeurospora sp., Metschnikowia sp., and Sporidiobolus salmonicolor (Carrasco et al 2012). A cold-adapted chitinase from G. antarctica that exhibited optimum activity at 15°C and pH 4.0 was expressed in P. pastoris, and its activity increased in presence of K ?…”

“…Several Antarctic yeast species able to growth in media with soluble starch as unique carbon source and displaying extracellular soluble starch hydrolyzing activity have been reported [33,34]. From these yeasts, an isolate identified as Dioszegia fristingensis displayed the highest starch hydrolyzing activity.…”
