Протекторное действие супернатантов лизатов реликтовых бактерий Bacillus sp. из вечной мерзлоты на ДНК лейкоцитов крови лабораторных мышей (посвящается памяти Потапова В.Д.)

We examined Lizate of Bacillus Lyuba, which was isolated from ancient permafrost, on human. There were eighteen participants included in this study. All participants underwent daily taking of lizate of 109 bacterial cells, in 40% alcohol solution (about 2-4 ml) in the morning for one month...

Permafrost preserves a variety of viable ancient microorganisms. Some of them can be cultivated after being kept at subzero temperatures for thousands or even millions of years...

Permafrost underlies about 20% of the earth’s land surface (Ershov 1998), and a majority of the biosphere is constantly below +5◦C (Ashcroft 2000). Microorganisms have been recently found in ice-sediment communities in the surface layers of perennial and permanent lake ice...

In this study, we isolated and characterized bacterial strains from ancient (Neogene) permafrost sediment that was permanently frozen for 3.5 million years. The sampling site was located at Mammoth Mountain in the Aldan river valley in Central Yakutia in Eastern Siberia...

Permafrost covers nearly 65% of Russia’s territory and contains microorganisms which have remained viable over millions of years. Although DNA sequences from 106 years have been reported, the results are still limited. The preservation of DNA has great significance in studies of evolution...

Bacillus cereus strain F, collected from relict permafrost located in Siberia, was analyzed for probiotic activity in the mouse Salmonella enterica model. Viable bacterial cells were found in frozen soils taken at Mammoth Mountain in Yakutia from a depth below the level of seasonal thawing...

Реликтовые микроорганизмы, сохранившиеся в вечномерзлых породах геологических периодов времени, обладают уникальной устойчивостью к неблагоприятным факторам внутренней и внешней среды...

Многолетнемерзлые породы широко рас-пространены в северном полушарии, а их возраст достигает сотен тысяч и миллионов лет. Они со-держат живые микроорганизмы, которые из-за сравнительно высокой температуры среды (-2 - -8ºС) не содержат льда...
