Enzymatic and Antimicrobial Activities in Polar Strains of Microscopic Soil Fungi.

Potential to produce inducible enzymes (several hydrolases and oxidases) and antibiotics as secondary metabolites was studied in soil micromycete strains from the Arctic (Franz Josef Land and Novaya Zemlya) and Antarctica (the oases Thala Hills, Larsemann Hills, Schirmacher, and Marie Byrd Land). Maximal esterase activity was observed in strains of two typical Antarctic species, Hyphozyma variabilis 218 and Thelebolus ellipsoideus 210 (51 and 29 nmol FDA/((g mycelium h), respectively). Cellulolytic activity was maximal (89 µmol glucose/mg biomass) in Ascochyta pisi 192.
