... first to apply freeze-treatment to plants as early as at the end of the 19th century. He kept corn grains in snow for two weeks before planting and succeeded in producing mature corn ears under climatic conditions of St. Petersburg. Certainly, many microorganisms (bacteria and yeasts) survive well low and even superlow temperatures. Actually, this ability underlies methods for their long-term storage. Tolerance to frost is usually provided by dehydration, increase in the viscosity of the cytoplasm,...

Microbes: Keeping it Going

... only be a modification made to the system that had been crafted by those invisible things when they were given full reign All free-living organisms are fueled by redox reactions. The most primitive microbial community is the one of hydrogenotrophic microorganisms . The reducing agent they use is hydrogen, which is produced by water reacting with overheated rock, that is at quite high temperatures. Such organisms occur widely among the microflora living in rock pores at depths exceeding 3 km. Thus,...
