| Summary: | An aqueous suspension of microorganisms was placed in sand which was enriched by organic substances. Test tubes with sand were placed open into a low pressure chamber of a photostat device, where they were kept for 2-14 days in an atmosphere of carbon dioxide at a pressure of 10 mm Hg. The temperature throughout the day changed from +25 to -25 C. The most resistant of the museum cultures tested were the strains of Mycococcus luteus, but among the microorganisms separated from Antarctic soil there were two unidentified forms: C sub 1 and A sub 14. Concentration of cells in these cultures increased during the tests by 1-2 orders. |
