Sporotomaculum Brauman et al. 1998
General information
Description and emendation
Sporotomaculum a spore forming sausage-shaped organism). Gram-positive, strictly anaerobic. Metabolism fermentative, inorganic electron acceptors not used. Formation of central, spherical endospores. Strictly anaerobic chemoorgano heterotroph. Growth on 3-hydroxybenzoate as sole source of carbon and energy. No growth with pyruvate, DL-lactate, succinate, fumarate, malate, citrate, valerate, pimelate, crotonate, crotonate with H2/CO2 atmosphere (80:20%, v/v), caproate, adipate, hexanoate, heptanoate, cyclohexane carboxylate, ethanol, methanol, D-fructose, glucose, benzoate, 2-hydroxybenzoate, 4-hydroxybenzoate, 3-aminobenzoate, 4-aminobenzoate, 2,3-dihydroxybenzoate and 2,5-dihydroxybenzoate, α-resorcylate, β-resorcylate and γ-resorcylate, protocatechuate, gallate, syringate, ferulate, caffeate, hydroxycinnamate, terephthalate, phenylacetate, 2-chlorobenzoate, 3-chlorobenzoate and 4-chlorobenzoate, phenol, catechol, resorcinol, hydroquinone, phloroglucinol, pyrogallol, 2-cresol, 3-cresol and 4-cresol. 3-Hydroxybenzoate is fermented to butyrate, acetate and CO2. No reduction of nitrate, sulfate, thiosulfate, sulfite, ferric iron, oxygen or fumarate. Growth requires sulfide-reduced mineral media. Addition of small amounts of dithionite shorten the lag phase. Yeast extract and tryptone stimulate but are not required for growth. Selective enrichment in sulfide-reduced freshwater mineral medium with 3-hydroxybenzoate as substrate. Growth in the pH range of 6.8-8.1, optimum at 7.3-7.6. Temperature range: 24-37°C, optimum around 30°C. Cytochromes not detected. DNA G+C content: 48 mol%. Habitat: guts of Cubitermes speciosus.
