Perhaps it is just his size that has allowed the microorganism to survive in the ice, says Loveland-Curtze. She assumes that Herminiimonas glaciei lived in fine water veins between ice crystals. His scourges might have helped him to move in the waterways and find food. The snow also contains remnants of fungal or plant spores, other bacterial cells, dust and minerals that may have fed Herminiimonas glaciei. Because of its small size, the bacterium could possibly occupy a place for which most other living things would have been too large.
Scientists speculate that similar microorganisms in the ice may have originated on other planets than Earth, such as in ice at poles on Mars or an ice-covered ocean on Europe, a Jupiter's moon. The results of this study could also shed light on how cells behave under these extremely harsh conditions? Temperatures down to minus 56 degrees Celsius, low oxygen, low nutrients, high pressure and limited space? survive or even grow. Another thing that makes Herminiimonas glaciei interesting for research is that the bacterium, which has been completely isolated for more than 100, 000 years, is resistant to the majority of conventional antibiotics. Why, the researchers do not know yet.Jennifer Loveland-Curtze (Pennsylvania State University in Park) et al .: International Journal of Systematic and Evolutionary Microbiology, doi: 10.1099 / ijs.0.001685-0 ddp / science.de?
