Abstract
Gram-stain-positive, aerobic, and nonmotile actinobacteria. Vegetative hyphae are produced but not aerial mycelia. Short spore chains arise from the substrate hyphae. Abundant globose bodies are formed at the end of the hyphae. Positive reaction for catalase and oxidase. Grows between 4 and 40°C, pH 6–9, and in the presence of 1% NaCl. Some strains require thiamine for growth. Chemoorganotrophic. Gelatin, starch, and Tweens 20, 40, 60, and 80 are degraded. Complex carbohydrates serve as carbon sources. The cell-wall contains meso-diaminopimelic acid, but 3-hydroxy diaminopimelic acid may also be present. The whole-cell sugar hydrolysate profile is complex and includes xylose, galactose, mannose, ribose, arabinose, rhamnose, and glucose. MK-9(H6) is the predominant menaquinone. The phospholipid composition includes diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, and phosphatidylinositol mannosides. Phylogenetically related to members of the family Micromonosporaceae and closely related to the genera Allocatelliglobosispora, Catellatospora, and Catelliglobosispora
