Abstract

A group of 15 psychrophilic pink pigment producing bacteria investigated in the present study were retrieved from different inorganic samples collected in Antarctica (J. G. Mendel Station, James Ross Island) during the period of 2007 2010. The majority of isolates were Gram-negative, catalase positive rods, only one isolate represented Gram-positive coccus (Arthrobacter sp.). Phylogenetic position of all isolates was determined by partial 16S rDNA sequence analysis which assigned the Gram-negative isolates as members of sphingobacteria or oxalobacteria. Individual strains were phylogenetically placed within the genera Pedobacter (four strains), Massilia (four strains) and Hymenobacter (three strains). Remaining three Gram-negative isolates were classified as members of Massilia/Duganella/Janthinobacterium group. These cold-adapted bacteria represent probably novel species within the genera listed above and they might serve as sources of novel biochemical traits usable in biotechnological applications.
