A Gram-stain-negative, yellow-pigmented bacterial strain, designated PR1012KT, 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 Spirosoma (97.50- 90.74% 16S rRNA gene sequence similarities) and showed highest sequence similarity to Spirosoma panaciterrae DSM 21099T (97.50%). Its predominant fatty acids included summed feature 3 (C16:1ω7c and/or C16:1ω6c), C16:1ω5c, iso-C15:0 and summed feature 4 (iso-C17:1 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 PR1012KT represents a novel species in the genus Spirosoma, for which the name Spirosoma aerolatum sp. nov. is proposed. The type strain is PR1012KT (=KACC 17939T=NBRC 110794T).
