Notes:
- ⏲ According to Madhaiyan et al. (2020), this species is a later heterotypic synonym of Streptomyces variegatus Sveshnikova and Timuk 1986. Publication: Madhaiyan M, Saravanan VS, See-Too WS. Genome-based analyses reveal the presence of 12 heterotypic synonyms in the genus Streptomyces and emended descriptions of Streptomyces bottropensis, Streptomyces cellulo fl avus, Streptomyces fulvissimus, Streptomyces glaucescens, Streptomyces murinus, and Streptomyces variegatus. Int J Syst Evol Microbiol 2020; 70:3924-3929.
- ❗ Streptomyces flavovariabilis is the correct name instead if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Streptomyces.
- ✏ The authority of the taxon name (Sveshnikova) deliberately differs from the authors of the publication (Gauze et al.).
- 😷 The risk group for Canada has been imported on 2024-02-27. The full classification is: risk group = 1, note = "Security sensitive biological agent: No - Terrestrial animal pathogen under Canadian Food Inspection Agency authority: No". — The risk group for Swiss Confederation has been imported on 2024-02-01. The full classification is: risk group = 1. — The risk group for Germany has been imported on 2023-10-29. The full classification is: risk group = 1. — If in doubt, use the risk group given in the regulations for your country and, if these are not available, use the risk group given in the catalogue of the culture collection from which you have obtained or intend to obtain the strain.
