Abstract Pa.lu'di.ba'cu.lum. L. n. palus –udis a swamp, marsh; N. neut. n. baculum a stick, rod; N.L. neut. n. Paludibaculum rod‐shaped bacterium from wetland. Acidobacteria / Acidobacteriia / Bryobacterales / Bryobacteraceae / Paludibaculum The genus Paludibaculum is represented by Gram‐negative, non‐spore‐forming, and nonmotile rods that occur singly, in pairs, or in short chains and reproduce by binary fission. These bacteria are facultatively anaerobic, mildly acidophilic, and mesophilic chemoorganotrophs, which utilize sugars and some polysaccharides. The only currently described species of this genus, Paludibaculum fermentans , was isolated from a littoral wetland of a boreal lake. Capable of fermentation and dissimilatory Fe(III) reduction under anoxic conditions. Major fatty acids are iso‐C 15 :0 and C 16 :1 ω7 c ; the cells also contain significant amounts of 13,16‐dimethyl octacosanedioic acid. The quinone is MK‐8. Known habitats are acidic wetlands and groundwater bodies. Members of the class Acidobacteriia , order Bryobacterales , family Bryobacteraceae . DNA G + C content (mol%) : 60.5. Type species : Paludibaculum fermentans Kulichevskaya, Suzina, Rijpstra, Sinninghe Damsté and Dedysh 2014, 2861 VP .
