Euzebyella algicola sp. nov., a marine bacterium of the family Flavobacteriaceae, isolated from green algae

A Gram-negative, yellow-pigmented, non-flagellated, gliding, rod-shaped and aerobic bacterium, designated MEBiC 12267 T , was isolated from green algae of Jeju Island. 16S rRNA gene sequence analysis revealed that the strain MEBiC 12267 T was affiliated to the genus Euzebyella of the family Flavobacteriaceae and showed the highest similarity to Euzebyella marina KCTC 42440 T (98.5 %). The DNA-DNA relatedness value of strain MEBiC 12267 T with E. marina KCTC 42440 T was 25 %. Growth was observed at 10-37 °C (optimum, 30-33 °C), at pH 6.0-9.5 (optimum, 8.0-8.5) and with 0.5-9.0 % (w/v) NaCl (optimum, 2.5-3.5 %). The predominant cellular fatty acids were iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The major respiratory quinone was MK-6. Polar lipids included phosphatidylethanolamine, seven unidentified lipids and two unidentified aminolipids. The DNA G+C content was 40.7 mol%. On the basis of the data from the polyphasic taxonomic study, it was concluded that the strain MEBiC 12267 T represents a novel species within the genus Euzebyella, for which the name Euzebyella algicola sp. nov. is proposed. The type strain of E. algicola is MEBiC 12267 T (=KCCM 43264 T =JCM 32170 T ).
