Cold-active enzymes are produced by organisms that inhibit environments such as polar regions, ocean depths, and high altitudes where temperature is low throughout the year. Typically, such biocatalysts not only exhibit their highest activity below 25ºC [1], but are also heat sensitive – making them ideal for applications that require mild processing conditions. Consequently, cold-active...
