Dactylosporangium aurantiacum is a Gram-positive soil-based actinobacterium in the family Micromonosporaceae. [1] Like all Dactylosporangium species, aurantiacum is aerobic and mesophilic. [2]
One subspecies, hamdenesis, produces a number of 18-membered macrolide antibiotics called tiacumicins as a byproduct of fermentation. [3] One of these, tiacumicin B, commonly known as fidaxomicin, [4] has narrow-spectrum bacteriocidal action against Gram-positive anaerobic bacteria, including Clostridioides difficile .
