Research output: Contribution to journalArticlepeer-review


Strain H38T was isolated during a study on the diversity of culturable psychrotolerant bacteria in raw milk. Comparative 16S rRNA gene sequence analysis showed that strain H38T belongs to the genus Chryseobacterium (family Flavobacteriaceae, phylum Bacteroidetes), with the highest similarity (96.7%) to Chryseobacterium hispanicum VP48T. Strain H38T grows aerobically, at 4-41 °C, with 0-2.5% NaCl and at pH 6.5-10.5. Light induces the formation of yellow carotenoid pigments. The dominant cellular fatty acids are 15:0 iso (41.6%), 15:0 anteiso (16.6%) and 17:0 iso 3-OH (10.3%). The G+C content of the DNA is 37.8 mol%. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain H38T (=LMG 24029T =DSM 19056T) is classified in the genus Chryseobacterium as the type strain of a novel species, for which the name Chryseobacterium haifense sp. nov. is proposed.
