The transfer of an integrated ICE element from the donor to recipient bacterium must be preceded by its excision from the chromosome that is co-promoted by small DNA-binding proteins, the so-called recombination directionality factors. The dynamics of the integration and excision processes are specific to each integrative and conjugative element.
Distribution of most nematode species is correlated negatively with elevation (due to temperature and precipitation) and salinity, and positively with soil moisture, soil organic matter, and nutrient availability. [3] Eudorylaimus spp. is the second most abundant nematode, followed by Plectus murrayi who are the least abundant nematodes. [3]
Antifreeze proteins (AFPs) or ice structuring proteins refer to a class of polypeptides produced by certain animals, plants, fungi and bacteria that permit their survival in temperatures below the freezing point of water. AFPs bind to small ice crystals to inhibit the growth and recrystallization of ice that would otherwise be fatal. [3]
Microbiology (from Ancient Greek μῑκρος (mīkros) ' small ' βίος (bíos) ' life ' and -λογία ' study of ') is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells).

A microbiome (from Ancient Greek μικρός (mikrós) ' small ' and βίος (bíos) ' life ') is the community of microorganisms that can usually be found living together in any given habitat. It was defined more precisely in 1988 by Whipps et al. as "a characteristic microbial community occupying a reasonably well-defined habitat which has ...
Brine salinity can increase to as much as 100 PSU when sea ice temperature reaches ~3 °C below the freezing point of seawater. [5] Brine temperature typically ranges from -1.9 to -6.7 °C in the winter. [6] Sea ice temperatures fluctuate in response to irradiance and atmospheric temperatures, but also change in response to the volume of snowfall.
Microorganisms, or microbes, span all three domains of life – bacteria, archaea, and many unicellular eukaryotes including some fungi and protists.Typically defined as unicellular life forms that can only be observed with a microscope, microorganisms were the first cellular life forms, and were critical for creating the conditions for the evolution of more complex multicellular forms.
