Motsamai and Kwetane, Thembelani,, 53, 801-805 (2003), doi = https://doi.org/10.1099/ijs.0.02341-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= An actinomycete with blue substrate mycelium was isolated from a soil sample in Cape Town, South Africa, and designated strain PK-BlueT. The colour of the substrate mycelium was not sensitive to changes in pH. The organism produced hairy spores in Spirales-type spore chains. Chemical taxonomy indicated that it belonged to the genus Streptomyces. Strain PK-BlueT produced no diffusible pigments other than melanin, grew at 45 °C, did not degrade adenine and exhibited no antibacterial activity against Enterococcus faecium, Escherichia coli or Pseudomonas aeruginosa. Analysis of its 16S rRNA gene sequence and the results of physiological tests showed that strain PK-BlueT (=DSM 41797T=ATCC BAA-411T) represents the type strain of a novel species of Streptomyces, for which the name Streptomyces speibonae sp. nov. is proposed., language=, type=
