An orange pigmented bacterium, S1, was isolated from a cyanobacterial mat sample collected in the vicinity of Schirmacher Oasis, Maitri, the Indian station, in Antarctica. The bacterium is Gram-positive and possesses all the characteristics of the genus Planococcus. It is non-sporulating, motile and has A4α type peptidoglycan, MK-7 and MK-8 as the major menaquinones and anteiso-C15:0 as the major fatty acid. Based on the phylogenetic characteristics, the bacterium S1 is identified as a close relative of Planococcus citreus with which it shares 98.12% similarity at the 16S rRNA gene level but exhibits a low similarity of 52% at the whole genome level. Apart from the above major differences, S1 also exhibits phenotypic differences with Planococcus citreus and other members of the genus Planococcus. Based on these differences, the bacterium S1 is identified as a new species of the genus Planococcus for which the name Planococcus maitriensis is proposed. The type strain of Planococcus maitriensis is S1T (= MTCC 4827; DSM 15305).
