Thermus ruber sp. nov., nom. rev. Loginova, L. G. and Egorova, L. A. and Golovacheva, R. S. and Seregina, L. M.,, 34, 498-499 (1984), doi = https://doi.org/10.1099/00207713-34-4-498, publicationName = Microbiology Society, issn = 1466-5026, abstract= The name Thermus ruber Loginova, Egorova, Golovacheva, and Seregina 1975 is revived for the same organism on which the original description was based. The temperature range for growth on a potatopeptone-yeast extract medium is 37 to 70°C, and the optimum temperature for growth is 60°C. T. ruber is characterized by the production of an intracellular bright red (or occasionally bright orange) carotenoid pigment with an absorption spectrum similar to that of retro-dehydro-γ-carotene (or occasionally neuro-sporaxanthine). The type strain is strain 1258 in the All-Union Collection of Microorganisms, Moscow, USSR., language=, type=
