Abstract
Ca.lor.an.ae.ro.bac'ter. L. n. calor heat; Gr. pref. an not; Gr. n. aer air; N.L. bacter masc. equiv. of Gr. neut. dim. n. bakterion small rod or staff; N.L. masc. n. Caloranaerobacter a thermophilic, anaerobic rod Firmicutes / “Clostridia” / Clostridiales / Clostridiaceae / Caloranaerobacter Motile rod‐shaped cells. Under optimal conditions are short rods, about 0.3–0.5 × 0.5–2 µm, found singly, in pairs, or in short chains (less than 5 cells). Gram‐stain‐negative. Thermophilic; temperature range for growth 45–65 °C, optimum growth at 65 °C. Adapted to the pH and salinity of ocean waters. pH range 5.5–9.0, optimum pH 7.0. Salinity range 10–100 g sea salts per liter, optimum 30 g sea salts per liter. Anaerobic, chemoorganotrophic, able to ferment carbohydrates and proteinaceous substrates. Sulfur not required for growth. On the basis of 16S rRNA gene sequence analysis presented in the roadmap to Volume 3 (Figure 5), Caloranaerobacter is located in the family Clostridiaceae, order Clostridiales, class Clostridia, in the phylum Firmicutes; formerly, it was classified in cluster XII of the Clostridium subphylum (Collins et al., 1 9 9 4). DNA G+C content (mol%): 27 (Tm). Type species: Caloranaerobacter azorensis Wery, Moricet, Cueff, Jean, Pignet, Lesongeur, Cambon‐Bonavita and Barbier 2 0 0 1, 1795VP.
