Sporosarcina macmurdoensis sp. nov., from a cyanobacterial mat sample from a pond in the McMurdo Dry Valleys, Antarctica

Abstract: Strain CMS 21w T was isolated from a cyanobacterial mat sample taken from a pond located in the McMurdo Dry Valleys, Antarctica. Based on its phenotypic, chemotaxonomic and phylogenetic properties, strain CMS 21w T was identified as a member of the genus Sporosarcina. At the 16S rRNA gene level, CMS 21w T exhibited about 93-96 % similarity to all reported species of Sporosarcina and exhibited a maximum similarity of 96 % to both Sporosarcina globispora and Sporosarcina psychrophila. Based on more than 3 % diff… Show more

“…Of bacteria assigned to Firmicutes, Planococcus rifietensis and Paenisporosarcina macmurdoensis were the dominant species, which have ever been previously isolated from algal or cyanobacterial mats in sulfurous springs (Reddy et al , 2003; Romano et al , 2003). Four Planomicrobium species were also found, which have been previously isolated from coastal sediments (Dai et al , 2005), seafood jeotgal (Yoon et al , 2001) and glaciers (Zhang et al , 2009a); they were considered as the cold tolerant bacteria (Yang et al , 2011; Zhang et al , 2009a).…”

“…Members of the Paenisporosarcina have been documented in a variety of permanently cold environments, including permafrost [50,55], arctic saline springs [57], alpine glaciers [58] and the McMurdo Dry Valleys [59], implying this group may have specific adaptations to low temperature conditions. Due to the concentration of solutes into the premelt phase during freezing, microorganisms found in the unfrozen fraction of ice are subjected to considerable osmotic stress.…”

“…The cultivable bacterial diversity was explored extensively from various habitats such as soil (Miwa, 1975;Yi and Chun, 2006;Ruckert, 1985;Shivaji et al, 1988;1989a;1989b;1991;Wery et al, 2003;Bozal et al, 2007), water (Lo Giudice et al, 2012;Michaud et al, 2012;Soller et al, 2000;Labrenz et al, 2000;Cristóbal et al, 2011), algal mats (Reddy et al, 2000;2002;2003a;2003b;Van Trappen et al, 2002;Spring et al, 2003;Peeters et al, 2011), ice Antibus et al, 2012;Bowmen et al, 1998) and sediments (Shivaji et al, 2011;Yu et al, 2011) and reviewed by Shivaji and Reddy (2009) (Hirsch et al, 2004;Antibus et al, 2012;Franzmann & Dobson, 1992;Chattopadyay et al, 2014). Among the Proteobacteria, Gammaproteobacteria leads in abundance in soil (3%) and water (0.6%) while members of Epsilonproteobacteria were absent (Reddy et al, 2016 (Reddy et al, 2016 Chattopadhyay et al, 2014;Reddy et al, 2016).…”
