[Psychrophilic pseudomonas from soil]

A psychrophilic culture of Pseudomonas inhabiting soil was cultivated at a temperature close to the minimum one (0 degrees C) and at a temperature close to a maximum one 28 degrees C) for growth on the original and diluted MPB. No changes were found in the formation of biomass, RNA and DNA. The maximum possible biomass yield was attained sooner at 0 degrees C on a diluted medium than on an original medium. At a low temperature, the specific growth rate remained the same, but the content of RNA increased.
