The temperature downshift results in (1) decrease in membrane fluidity (2) changes in nucleic acid structures (3) reduced ribosome function (4) inefficient protein folding. Bacteria respond to this low temperature change by producing cold-shock proteins (CSPs) that bind to single-stranded RNA and DNA thereby, maintaining cell physiology. CSPs have been widely studied in Escherichia coli and Bacillus subtilis. Here we discuss the cold adaptation by desaturase system, RNA chaperone, and transcription antitermination function of CspA homologues.

Keywords: Bacterial adaptation, Cold, Temperature.
