Cold-loving Bacteria from Antarctic and Arctic: Occurrence, Survival and Usefulness

Introduction Psychrophilic (cold-loving) bacteria are extremophiles that define the lower limits of temperature for the survival of life forms. They survive and multiply at temperatures as low as -20oC and rarely survive above 30oC. Such bacteria are predominant in habitats that are permanently cold, such as Antarctic, Arctic, glaciers, deep sea etc. Psychrophiles play a key role in the cold habitats by facilitating nutrient recycling and producing bioactive molecules, biopharmaceuticals and extremozymes. Psychrophiles could thus serve as potential workhorses in...
