Many archaea occur in extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties and specific extremozymes, they are a potentially valuable resource in the development of novel biotechnological processes.

Keywords: extremophiles, archaea, extremozymes

The main direction of whey processing is production of lactic acid in the process of lactic fermentation. Lactic acid can be used to produce fully biodegradable polymer [poly(lactic acid)] (PLA), in the process of direct polymerization, directly from lactic acid, and in indirect polymerization. This study reviews the...
