| الوصف: | We report the isolation and properties of several species of bacteria from Siberian permafrost. Half of the isolates were spore-forming bacteria unable to grow or metabolize at subzero temperatures. Other Gram-positive isolates metabolized, but never exhibited any growth at - 10 degrees C. One Gram-negative isolate metabolized and grew at - 10 degrees C, with a measured doubling time of 39 days. Metabolic studies of several isolates suggested that as temperature decreased below + 4 degrees C, the partitioning of energy changes with much more energy being used for cell maintenance as the temperature decreases. In addition, cells grown at - 10 degrees C exhibited major morphological changes at the ultrastructural level. |
