Chryseobacterium solincola sp nov., isolated from soil

A Gram-staining-negative, yellow-pigmented, strictly aerobic bacterium, designated strain 1YB-R12(T), was isolated from a soil sample in western Algeria. The novel isolate was heterotrophic, chemoorganotrophic, halotolerant and psychrotolerant. The temperature and pH optima for growth were 28-30 degrees C and pH 7.3-8. The bacterium tolerated up to 6% (w/v) NaCl. Cells were non-motile, non-gliding and non-spore-forming, and were characterized by a variable morphological cycle. Flexirubin-type pigments were not detected. 16S rRNA gene sequence analysis showed that strain 1YB-R12(T) occupied a distinct lineage within the genus Chryseobacterium and shared highest sequence similarity with Chryseobacterium haifense LMG 24029(T) (96.5%). The DNA G+C content of strain 1YB-R12(T) was 40.9 mol%. The predominant cellular fatty acids were anteiso-C-15:0 (41.4%) and iso-C-15:0 (14.4%). On the basis of phenotypic properties and phylogenetic distinctiveness, strain 1YB-R12(T) is considered to represent a novel species of the genus Chryseobacterium, for which the name Chryseobacterium solincola sp. nov. is proposed. The type strain is 1YB-R12(T) (=DSM 22468(T)=CCUG 55604(T)).
