Caryophanon

Ca.ry.o'pha.non. Gr. n. karyon nut, kernel, nucleus; Gr. adj. phaneros bright, conspicuous; N.L. neut. n. Caryophanon that which has a conspicuous nucleus. Firmicutes / “Bacilli” / Bacillales / Planococcaceae / Caryophanon Slightly curved to straight multicellular rods (trichomes) with rounded or slightly tapered ends. Cell diameter is 1.0–3.5 µm and length is 4–20 µm or more. Several trichomes may form short chains. Asporogenous, nonbranching. Gram‐positive. Motile by means of peritrichous flagella. After isolation in pure culture, the typical cell morphology may be preserved only in liquid media containing cow dung. Strictly aerobic. Chemoorganotrophic with presumed respiratory metabolism. Carbohydrates are not used as substrates. Acetate and other organic acids are the only major carbon sources used. Biotin is required and thiamine is stimulatory. Catalase‐positive; cytochrome oxidase‐negative; indole not produced. Found associated with cattle dung. Not known to be pathogenic . DNA G + C content ( mol %): 41–46 ( T m ). Type species : Caryophanon latum Peshkoff 1939, 244 AL .
