Randomized trial shows bacterial incorporation of macromolecules at -15°C, indicating cold-adaptive synthesis capability.

The aim is to investigate the ability of bacteria to incorporate DNA and protein precursors into macromolecules at low temperatures.
Bacterial cell suspensions incubated at -15°C for 50 to 100 days
Assessment of macromolecular synthesis through incorporation into trichloroacetic acid-precipitated material
Evaluation of inhibition by antibiotics
Macromolecular synthesis occurred at -15°C but not at -70°C
Incorporation was significantly inhibited by the presence of antibiotics
Findings suggest bacterial adaptation to cold environments similar to glacial ice conditions

Brent C. Christner (2002) studied this question.
