Psychrophilic (cold loving) bacteria have interested me for close to two and half decades. This interest has taken me to Antarctica in 1984 and 1995 and to the Arctic in 2007 and 2010. My objectives are to establish the identity of these cold loving bacteria, to understand the molecular basis of survival at freezing temperatures and to use them for bitechnological applications. The effort has resulted in the description of about 40 new species of bacteria from diverse cold habitats. In addition it has also led to the identification of three genes required for the survival of bacteria at low temperatures. A few of the recent publications are listed below:
