KibdelosporangiumRANK: GenusTAXONOMY: Bacteria -> Terrabacteria group -> Actinobacteria -> Actinobacteria -> Pseudonocardiales -> Pseudonocardiaceae -> Kibdelosporangium OVERVIEW: Aerobic, catalase-positive, Gram-stain-positive, non-acid-fast, filamentous organisms that produce a substrate mycelium that penetrates the agar and forms a compact layer on top of the agar; aerial mycelium originates from the substrate mycelium. Substrate mycelium may exhibit varying degrees of fragmentation and usually bears specialized structures that appear to be dichotomously branched, septate hyphae radiating from a common stalk. The aerial mycelia bear long chains of spores and sporangium-like structures. The sporangium-like structures are surrounded by well-defined walls, but do not contain spores and germinate directly, producing one or more germ tubes when placed on solid growth media. Motile elements or spores are not present. Contains meso-diaminopimelic acid as the diamino acid. Whole-cell sugar pattern consists of arabinose and d-galactose, with traces of madurose usually present. The phospholipid pattern consists of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides, and phosphatidylmethylethanolamine. Mycolic acids are not present. DNA G+C content (mol%): 66 (Tm). Type species: Kibdelosporangium aridum |
