Taxonomic assessment and enzymes production by yeasts isolated from marine and terrestrial Antarctic samples
The aim of the present study was to investigate the taxonomic identity of yeasts isolated from the Antarctic continent and to evaluate their ability to produce enzymes (lipase, protease and xylanase) at low and moderate temperatures. A total of 97 yeast strains were recovered from marine and terrest...
