Abstract
Nesterenkonia sp. strain AN1 was isolated from Antarctic soil and is a polyextremophile, being tolerant of low temperatures, high salt concentrations, and high alkalinity. Here we report the draft genome sequence of this strain.

Nesterenkonia sp. strain AN1 was isolated from Antarctic soil and is a polyextremophile, being tolerant of low temperatures, high salt concentrations, and high alkalinity
Nesterenkonia sp. strain AN1 was isolated from Antarctic desert soil and represents the first reported psychrophilic representative of the genus [7]
The draft genome comprises 42 contigs, with an average size of 72,384 nucleotides, yielding a genome of ~3.05 megabases in size, with a mean GϩC content of 67.4%. These results are similar to the sizes (2.59 to 2.81 Mb) and GϩC contents (62.2 to 71.5%) observed in the draft genomes of three temperate strains of Nesterenkonia which are publically available [11]
Summary
Nesterenkonia sp. strain AN1 was isolated from Antarctic soil and is a polyextremophile, being tolerant of low temperatures, high salt concentrations, and high alkalinity. Antarctic desert soil represents one of the most extreme terrestrial environments on Earth [1, 2]. Microorganisms surviving in this environment possess several adaptive mechanisms to cope with the low temperatures, elevated pH, salt, high UV irradiation levels, and low water content typical of this harsh environment [3].
