Understanding Cold-Adapted Plant Growth-Promoting Microorganisms from High-Altitude Ecosystems

Psychrophiles are found almost in all the ecosystems at low temperatures. They are of great importance as they act as models to study the mechanics for survival at low temperature and can be used to extract several enzymes and secondary metabolites which are useful in various industries say healthcare, food, detergent, tannery, etc. This chapter focuses on the basic modifications of psychrophiles at cellular, molecular and functional levels, their applications in different spheres of life and how these strategies can be mimicked in human lives.
