sp. nov., aerobic photosynthetic bacteria isolated from a culture Free

Abstract

Two Gram-stain-negative, aerobic, non-motile, non-spore-forming and rod-shaped bacteria, designated strains T2 and T5, were isolated from a culture of from Daejeon, Republic of Korea. Comparative 16S rRNA gene sequence studies placed the new isolates in the class and, notably, most closely related to PE 4-5, DSM 3183 and KR-99 showing 99.4 %, 98.2 % and 97.9 % 16S rRNA gene sequence similarities, respectively. The two novel strains shared 100 % similarity with each other. The cells of strains T2 and T5 formed yellow colonies on R2A agar and contained Q-10 as the only ubiquinone, sphingoglycolipid, phosphatidylethanolamine, phosphatidylcholine, and phosphatidylglycerol as major polar lipids, and Cω6, summed feature 8 (Cω7 and/or Cω6), Cω8 and C as the major fatty acids (>5 %). The DNA G+C content of the genomes was determined to be 64.2 mol% for strain T2 and 64.4 mol% for strain T5. The DNA–DNA hybridization values of strains T2 and T5 with PE 4-5, DSM 3183, and KR-99 were 19.7–42.4 %. Based on the combined genotypic and phenotypic data, we propose that strains T2 and T5 represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is T2 (=KCTC 42354=JCM 30467).
