Lipases (3.1.1.3) are ubiquitous, biogenic enzymes which hydrolyses the triacylglycerols at water-oil interface. Many species of animals, plants, and microbes produces lipases. The organisms able to produce lipases could tolerate organic solvents, high temperature, is industrial interest. Apart from its natural aqueous catalysis it also performs synthetic reactions in non-aqueous conditions, ha...

The carbonic anhydrases (CAs) are mostly zinc-containing metalloenzymes which catalyze the reversible hydration/dehydration of carbon dioxide/bicarbonate. The CAs have been extensively studied because of their broad physiological importance in all kingdoms of life and clinical relevance as drug targets. In particular, human CA isoform II (HCA II) has a catalytic efficiency of 108 M-1 s-1, appro...

Pullulan is a unique biopolymer with many useful traits and hundreds of patented applications. However, despite the fact that pullulan has been in commercial production for more than 25 years, few of these potential uses have been widely adopted. In large part this may be due to the relatively high price of pullulan. Nevertheless, the last few years have seen a resurgence in interest in pullula...

Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite extensive research, however, there are few existing industrial applications of eithe...
