Abstract

A Gram-stain-negative, yellow-pigmented bacterial strain, designated PR1012K, was isolated from a motor car evaporator core collected in Korea. Cells of the strain were facultatively anaerobic, non-spore-forming and rod-shaped. The strain grew at 10–40 °C (optimum, 25 °C), at pH 6.5–8.0 (optimum, pH 7.0–8.0) and in the presence of 0–1 % (w/v) NaCl. Phylogenetically, the strain was closely related to members of the genus (97.50–90.74 % 16S rRNA gene sequence similarities) and showed highest sequence similarity to DSM 21099 (97.50 %). Its predominant fatty acids included summed feature 3 (Cω7 and/or Cω6), Cω5, iso-C and summed feature 4 (iso-C I and/or anteiso B) and it had MK-7 as the major menaquinone. The polar lipids present included phosphatidylethanolamine, one unknown aminophospholipid, two unknown aminolipids and five unknown polar lipids. The DNA G+C content of this strain was 54 mol%. Based on phenotypic, genotypic and chemotaxonomic data, strain PR1012K represents a novel species in the genus , for which the name sp. nov. is proposed. The type strain is PR1012K ( = KACC 17939 = NBRC 110794).
