Conclusions: A high diversity of yeasts was isolated in this work including undescribed species and species not
previously isolated from the Antarctic region, including Wickerhamomyces anomalus, which has not been isolated
from cold regions in general. The diversity of extracellular enzyme activities, and hence the variety of compounds
that the yeasts may degrade or transform, suggests an important nutrient recycling role of microorganisms in this
region. These yeasts are of potential use in industrial applications requiring high enzyme activities at low
temperatures.
widely in their ability to assimilate carbon sources (consuming from 1 to 27 of the 29 carbon sources tested). All
species displayed at least 1 of the 8 extracellular enzyme activities tested. Lipase, amylase and esterase activity
dominated, while chitinase and xylanase were less common. Two yeasts identified as Leuconeurospora sp. and
Dioszegia fristingensis displayed 6 enzyme activities.
