The data demonstrate that the guanine plus cytosine contents (GC values) of the representative cultures ranged from 30 to 53 %. A number of the recently proposed nomen species are shown to contain representatives with different GC values., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-58-2-171
