Reproduction and metabolism at − 10°C of bacteria isolated from Siberian permafrost
Summary 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°C. One Gram‐...
