Abstract
Um.e.za.wa'e.a. N.L. fem. n. Umezawaea named for Hamao Umezawa (1914–1986), of the Institute of Microbial Chemistry, Tokyo, in recognition of his leadership and contributions to the study of the biology and natural products of actinomycetes. Actinobacteria / Actinobacteria / Pseudonocardiales / Pseudonocardiaceae / Umezawaea Aerobic. Gram‐stain‐positive, non‐acidfast, nonmotile actinomycetes. Branched substrate mycelium (approx. 0.3–0.5 µm in diameter) is produced; aerial mycelia are formed on some media. Ovoid or cylindrical conidia (0.3–0.5 × 1.1–1.9 μm) are produced by fragmentation of substrate mycelium. Pseudosporangia are produced on some media. Contains meso ‐diaminopimelic acid as the diamino acid. The muramic acid in the cell‐wall peptidoglycan is acetylated. The whole‐cell sugar pattern consists of galactose, mannose, and ribose, with a trace of rhamnose. The phospholipid pattern consists predominantly of phosphatidylethanolamine, phosphatidylinositol, phosphatidylethanolamine containing hydoxylated fatty acids, and lyso ‐phosphatidylethanolamine. The predominant menaquinone is MK‐9(H 4 ), with a trace of MK‐10(H 4 ). Mycolic acids are absent. Has a fatty acid profile consisting predominantly of C 16:0 iso fatty acids, with C 14:0 iso, C 15:0 iso, C 16:0 , C 16:1 , C 17:1 , and C 16:1 iso as minor components. Phylogenetically, nearest neighbor is the genus Saccharothrix . DNA G + C content ( mol %): 74 (HPLC). Type species : Umezawaea tangerina (Kinoshita, Igarashi, Ikeno, Hori and Hamada 2000) Labeda and Kroppenstedt 2007, 2761 VP .
