Abstract

A Gram-stain negative, aerobic, non-motile bacterial strain, 23D10-4-9, was isolated from symptomatic canker bark tissue of . The isolate grew between 4 and 35 °C, with optimal growth occurring at 25 °C. The species was positive for catalase and negative for oxidase activity. Nitrate was not reduced to nitrite. It showed activities toward -galactosidase and -glucosidase. Citrate was not utilized. Acid was produced from -glucose. The major fatty acids were iso-C, Cω and iso-C 3-OH. The main polar lipid profiles of the novel isolate included phosphatidylethanolamine, phospholipids and seven unknown lipids. The predominant menaquinone of the novel isolate was MK-7. The DNA G+C content was 40.6 mol%. 16S rRNA gene data revealed that the novel isolate shares the greatest sequence similarity with 7Y-4 (96.1 %). Based on phenotypic and genotypic characteristics, the isolate represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is 23D10-4-9 (=CFCC 12640=KCTC 42248).
