[Effect of low temperature treatment of liquid nutrient media on the reproduction of microorganisms].
The development of bacterial cultures of 37 microbial strains was studied after their 4-5 and 24 hour cultivation in liquid thawed and normal nutrient media. The cultivation of gram-positive aerobic bacteria, facultative anaerobic bacteria, actinomycetes and moulds in pre-frozen nutrient media increased 2-4 fold their reproduction as compared to that in the media that were not prefrozen. An insigificant acceleration of growth was found in six strains of gram-negative aerobic bacteria.
