Abstract
Bacteria are one of the most versatile living creatures having ability to sustain life processes under various suboptimal conditions. Present work illustrates the impact of temperature and metallic stresses on a psychrotolerant bacterium isolated from Himalayan region in India. The bacterium was morphologically and biochemically characterized and identified as Pseudomonas veronii ASP36 based on the 16S rDNA sequencing followed by BLAST similarity search. Growth at low temperature incited the bacterium to produce more exopolysaccharides. Preincubation of the bacterium at near zero temperature enhanced its freeze tolerance. ZnSO4 induced genomic changes in the test isolate were revealed through RAPD.
