Cold-active microbial Lipases: a versatile tool for industrial applications
Lipases are a class of enzymes which catalyze the hydrolysis of long chain triglycerides and constitute the most important group of biocatalysts for biotechnological applications. Cold active lipases have lately attracted attention as a result of their increasing use in the organic synthesis of chiral intermediates. Due to their low optimum temperature and high activity at very low temperatures, which are favorable...
