20.500.12556/RUL-36579 Isolation and characterization of a novel violacein-like pigment producing psychrotrophic bacterial species Janthinobacterium svalbardensis sp. nov A bacterial strain designated JA-1, related to Janthinobacterium lividum, was isolated from glacier ice samples from the island Spitsbergen in the Arctic. The strain was tested for phenotypic traits and the most prominent appeared to be the dark red brown to black pigmentation different from the violet pigment of Janthinobacterium, Chromobacterium and Iodobacter. Phylogenetic analysis based on 16S rRNA gene sequences and DNA-DNA hybridization tests showed that strain JA-1 belongs to the genus Janthinobacterium but represents a novel lineage distinct from the two known species of this genus, J. lividum and Janthinobacterium agaricidamnosum. TheDNAG + C content of strain JA-1 was determined to be 62.3 mol %. The isolate is a psychrotrophic Gram negative bacterium, rod-shaped with rounded ends, containing intracellular inclusions and one polar flagellum. On the basis of the presented results strain JA-1 is proposed as the type strain of a novel species of the genus Janthinobacterium, for which the name Janthinobacterium svalbardensis sp. nov. is proposed (JA-1T = DSM25734,ZIM B637). mikrobiologija bakterije psihrotrofne bakterije Janthinobacterium svalbardensis pigmenti true false false Angleški jezik Neznan jezik Delo ni kategorizirano 2015-07-10 12:30:43 2015-07-10 12:30:43 2022-06-23 03:49:58 0000-00-00 00:00:00 2013 0 0 Str. 763-769 issue 4 Vol. 103 2013 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 579 0003-6072 10.1007/s10482-012-9858-0 3147912 5131015 http://download.springer.com/static/pdf/897/art%253A10.1007%252Fs10482-012-9858-0.pdf?auth66=1354969235_038af70ca72300adad29e7303bd340f3&ext=.pdf 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=36590 Biotehniška fakulteta 0 0 0
