It also highlights the unique survival strategies of these psychrophiles at the molecular, cellular, tissue and organism level. It also establishes their utility to mankind in the spheres of health, agriculture and medicine. A major part of the review includes studies carried by scientists in India in the above extreme cold habitats. Keywords: Diversity; Himalayan; Stratosphere; Antarctica Bacterial abundance of Antarctica, Arctic, 2004; Shivaji et al., 2013c), 0.2×102 to 107 cells ml–1 Himalayas and Stratosphere of water (Lo Giudice et al., 2012) and 8×106 to 2.4×107 cells g–1 of sediment (Stibal et al., 2012) and Antarctica, Arctic and Himalayan regions are 105 to 1010 cells g–1 of soil (Shivaji et al., 1988; 1989a, considered as highly arid, oligotrophic and extreme 1989b; Aislabie et al., 2009). The numbers were also cold habitats on the planet Earth and the abundant in cyanobacterial mats (Reddy et al., 2000, aforementioned parameters are known to influence 2002a, 2002b, 2003a, 2003b, 2003c, 2003d, 2004) and microbial diversity.
