Abstract
A Gram-negative, motile, facultatively anaerobic rod, designated A36T, was isolated from a dead ark clam found on the south coast of Korea. The isolate was catalase- and oxidase-negative. 16S rRNA gene sequence analysis indicated that strain A36T was most closely related to Kistimonas asteriae KMD 001T, with which it shared 98.2 % 16S rRNA gene sequence similarity. Strain A36T grew optimally at 30–37 °C, with 1 % (w/v) NaCl and at pH 8.0. The major respiratory quinone was ubiquinone-9 (Q-9). The major polar lipids were phosphatidylserine, phosphoethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The major fatty acids were summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 2-OH) and C16 : 0. The genomic DNA G+C content was 47.3 mol%. DNA–DNA relatedness between the isolate and K. asteriae JCM 15607T was <25±3 %. Strain A36T represents a novel species of the genus Kistimonas , for which the name Kistimonas scapharcae sp. nov. is proposed. The type strain is A36T ( = KACC 16204T = JCM 17805T). An emended description of the genus Kistimonas is also provided.
