Abstract
A Gram-negative, proteorhodopsin-containing, orange pigmented, rod-shaped and strictly aerobic bacterium, designated strain AKS622(T), was isolated from a glacier core collected from the coast of King George Island, Antarctica. 16S rRNA gene sequence analysis revealed that strain AKS622(T) was affiliated to the genus Nonlabens of the family Flavobacteriaceae and showed highest similarity to Nonlabens marinus S1-08(T) (97.9%). The level of DNA-DNA relatedness between strain AKS622(T) and N. marinus S1-08(T) was 46%. Optimal growth of strain AKS622(T) was observed at pH 7.0, at 15 degrees C and with 2.0% NaCl. The predominant cellular fatty acids were anteiso-C-15:0, iso-C-16:0, iso-C-16:0 3-OH, C-17:0 2-OH and summed feature 3 (comprising C-16:1 omega 7c and/or C-16:1 omega 6c). The DNA G C content was 37.9 molok. The major respiratory quinone was MK-6. Phosphatidylethanolamine, four unidentified glycolipids, three unidentified aminolipids and one unidentified lipid were detected as major polar lipids. On the basis of the data from this polyphasic taxonomic study, it was concluded that strain AKS622(T) represents a novel species within the genus Nonlabens, for which the name Nonlabens antarcticus sp. nov. is proposed. The type strain is AKS622(T) (=KCCM 43019(T)=JCM 14068(T)). Emended descriptions of N. marinus Park et al. 201 2 and Nonlabens agnitus Yi and Chun 201 2 are given.
