It's extremely hard to dig in permafrost, but from one of the core samples came the bacteria Planococcus halocryophilus… a champion of cold temperature survival. (lightsource.ca)
Planococcus halocryophilus bacterium growing at -15ºC in a 18% salt medium. (lightsource.ca)
Microscopic characterization of the bacterial cell envelope of Planococcus halocryophilus Or1 during subzero growth at− 15° C." Polar Biology (2015): 1-12. (lightsource.ca)
Planococcus halocryophilus OR1 grows at -15 °C, and Deinococcus geothermalis can grow at temperatures as low as -25 °C. Extremophilic microorganisms can also withstand high levels of radiation, for example, Deinococcus radiodurans, when exposed to conditions outside the International Space Station, tolerated radiation levels more than 200 times those that are present on Earth and survived 3 years of exposure in space.

Antonie van Leeuwen1
Observation of biofilms dates back to the seventeenth century when Antonie van Leeuwenhoek observed bacteria from the plaque biofilm of his teeth under his primitive microscope [ 2 ]. (intechopen.com)
20211
In 2021, bacteria such as Methylorubrum rhodesianum and Methylobacterium ajmalii were isolated from International Space Station, an extreme environment. (zintellect.com)
Survival2
Understanding how bacteria and other organisms adapt and evolve under extreme conditions has several applications in biomanufacturing and bioeconomy, micronutrient research, biosensor development, climate change, and human survival in extreme conditions etc. (zintellect.com)
This can include researching evolutionary drivers, environmental limitations, internal and external survival requirements, expression and control mechanisms associated with survival, functional characterization of unique biomolecules, and methods for translating extremophile-related research to drive novel capabilities in other organisms.

Organisms1
Biofilms are a mixture of complex communities of organisms mostly composed of diverse bacteria that vary depending on the surrounding environmental conditions induced by physical and chemical factors. (intechopen.com)
Study3
Whyte, along with a team that included Nadia Mykytczuk from Laurentian University, and John Lawrence of the National Hydrology Research Centre in Saskatoon, used the Canadian Light Source to study the bacteria. (lightsource.ca)
A total of 66 bacterial isolates were obtained in the study where detail study of 24 strains (12 Gram positive and 12 Gram negative) using morphological and biochemical characterization was conducted. (banglajol.info)

Extreme cold1
Bacteria found to survive at extreme cold temperatures are giving scientists the hope that they will find life in outer space, either on Mars, Jupiter's moon Europa, or Saturn's moon Enseladus. (lightsource.ca)
Life2
If there is life on Mars, Whyte thinks bacteria, like Planococcus, could be exactly what they find. (lightsource.ca)
The emergence of new agricultural practices, fertilisation methods, sources of amendments and plant nutrition, and use of bacteria and fungi to improve the efficiency of nutrient use by crops are interesting and sustainable solutions to maintain soil life, improve its fertility, and feed plants for sufficient and high-quality agricultural production to promote sustainable agriculture.
