Fig. 1. Colony morphology, microscopic image and genetic relationship with related taxa of R. aerofrigidensis. (A) Colonies on sheep blood agar. (B) Gram staining of the isolate (1,000×). (C) A neighbor-joining tree based on 16S rRNA gene sequences. The scale bar equals 0.0050 changes per nucleotide position. Bootstrap values are shown on nodes as percentages of 1,000 replicates.
