Thermoanaerobaculum

Abstract

Ther.mo.an.a.e.ro.ba'cu.lum. Gr. masc. adj. thermos , hot; Gr. pref. an- , not; Gr. masc. n. aer , air; L. neut. n. baculum , rod; N.L. neut. n. Thermoanaerobaculum , rod that grows in the absence of air at high temperatures. Acidobacteria / Thermoanaerobaculia / Thermoanaerobaculales / Thermoanaerobaculaceae / Thermoanaerobaculum Cells are Gram‐stain‐negative, nonmotile, strictly anaerobic, and rod shaped. Reproduce by binary fission. Chemoheterotrophic with the ability to grow fermentatively on pyruvate, yeast extract, or peptone. Capable of reducing Fe(III) and Mn(IV). Moderately thermophilic. The major fatty acids are iso‐C 15:0 , iso‐C 16:0 , anteiso‐C 17:0 , and iso‐C 17:0 . Iso‐diabolic acid and other ether‐linked lipids are not present. The polar lipids are diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine. The major isoprenoid quinone is MK‐10, and the major polyamine is sym ‐homospermidine. Phylogenetically, Thermoanaerobaculum is located in the phylum Acidobacteria within the family Thermoanaerobaculaceae , order Thermoanaerobaculales , and class Thermoanaerobaculia . Represents the first genus to be described within Acidobacteria subdivision 23. Known habitats are terrestrial hot springs. DNA G + C content (mol%) : 63.0 (genome sequence). Type species: Thermoanaerobaculum aquaticum Losey et al. 2013 VP .
