  • 🧍 According to Hill et al. (1984), on the Approved Lists of Bacterial Names, this nomenclatural name is incorrectly cited as Thermoactinomyces vulgaris Tsiklinsky (sic) 1899. However, the issue in which the original publication appeared uses the spelling "Tsiklinsky, P." more frequently than the spelling "Tsilinsky, P.", hence this correction may be unwarranted.
