Both aquatic and soil ecosystems are environments rich in polymericmaterial from the different structures of the organisms belonging to the threedomains of life that exist on our planet: Archaea, Bacteria, and Eukarya. Moreover,microbial communities play important roles in food webs, contributing to the regenerationof nutrients within these systems. The ecosystems of Patagonia andAntarctica could be taken into account as important reservoirs of microorganismswith potential biotechnological interest because of the cold-active hydrolyticenzyme activities produced there and also because of the diversity of enzymeproducingmicrobes. Cold-active amylase, pectinase, cellulase, carboxymethylcellulase,xylanase, galactosidase, glucosidase, chitinase, α-rhamnosidase, andprotease activities have been detected so far in bacterial isolates from the sub-Antarctic region. The same activities, plus lipase, urease, and esterase activities,have been reported for fungal isolates obtained from Patagonia and Antarctica.
