Optimal growth occurred at 37 °C, pH 6–7, with 1 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences classified the two strains to the genus Actinomyces , with highest 16S rRNA gene sequence similarity (95 %) to type strains of Actinomyces haliotis , Actinomyces radicidentis and Actinomyces urogenitalis . The major cellular fatty acids were C18 : 1ω9c and C16 : 0. MK-10(H4) was the major respiratory quinone. The genomic DNA G+C content of the isolate was 54.4 mol%. DNA–DNA hybridization values with the most closely related species of the genus Actinomyces was 24.6 %. The two strains can be differentiated from the most closely related species such as A. haliotis , A. radicidentis, A. graevenitzii and A. urogenitalis by a list of carbohydrate fermentations and enzyme activities. On the basis of physiological, biochemical and phylogenetic analysis, strains VUL7T and VUL8 represent novel species of the genus Actinomyces , for which the name Actinomyces vulturis sp. nov. is proposed. The type strain is VUL7T (=CGMCC 4.7366T=DSM 103437T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.001851
