Caenispirillum humi sp. nov., a bacterium isolated from the soil of Korean pine garden A novel bacterial strain MAH-8T was isolated from a soil sample of a Korean pine garden and was characterized using a polyphasic approach. Cells were Gram-staining negative, pinkish yellow colored, motile and vibrio-shaped. The strain was aerobic and catalase, oxidase positive, optimum growth temperature and pH were 28–30 °C and 7.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain MAH-8T belongs to the genus Caenispirillum and is most closely related to Caenispirillum bisanense KCTC 12839T (98.14%), Caenispirillum deserti KCTC 42064T (96.35%), and Caenispirillum salinarum JCM 17360T (95.76%). In DNA–DNA hybridization tests, the DNA relatedness between strain MAH-8T and its closest phylogenetic neighbor was below 45.0%. The DNA G + C content was 70.5 mol% and the predominant respiratory quinone was ubiquinone-10. Flexirubin-type pigments were present and the major cellular fatty acids were C18:1 ω7c/C18:1 ω6c, C16:1 ω7c/C16:1 ω6c and C16:0. The results of DNA–DNA hybridization and genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that strain MAH-8T represented a novel species within the genus Caenispirillum, for which the name Caenispirillum humi, is proposed.

Abstract

A novel bacterial strain MAH-8T was isolated from a soil sample of a Korean pine garden and was characterized using a polyphasic approach. Cells were Gram-staining negative, pinkish yellow colored, motile and vibrio-shaped. The strain was aerobic and catalase, oxidase positive, optimum growth temperature and pH were 28–30 °C and 7.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain MAH-8T belongs to the genus Caenispirillum and is most closely related to Caenispirillum bisanense KCTC 12839T (98.14%), Caenispirillum deserti KCTC 42064T (96.35%), and Caenispirillum salinarum JCM 17360T (95.76%). In DNA–DNA hybridization tests, the DNA relatedness between strain MAH-8T and its closest phylogenetic neighbor was below 45.0%. The DNA G + C content was 70.5 mol% and the predominant respiratory quinone was ubiquinone-10. Flexirubin-type pigments were present and the major cellular fatty acids were C18:1 ω7c/C18:1 ω6c, C16:1 ω7c/C16:1 ω6c and C16:0. The results of DNA–DNA hybridization and genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that strain MAH-8T represented a novel species within the genus Caenispirillum, for which the name Caenispirillum humi, is proposed. The type strain is MAH-8T (= KACC 19294T = CGMCC 1.16224T). The NCBI GenBank Accession Number for the 16S rRNA gene sequence of strain MAH-8T is KY964275.
