Eubacteriaceae Ludwig et al. 2010
General information
Description and emendation
The family Eubacteriaceae is circumscribed for this volume on the basis of phylogenetic analyses of the 16S rRNA gene sequences and includes the genus Eubacterium and its close relatives. However, large numbers of validly published species have historically been misclassified within this genus. They continue to be described in the Eubacterium chapter although, based on their phylogenetic assignment, they belong to other families (Wade, this volume). More recent investigations suggest that the genus Eubacterium should be restricted to the type species Eubacterium limosum and it close relatives, such as Eubacterium aggregans, Eubacterium barkeri, and Eubacterium callanderi. The family is then restricted to genera related to these species, such as Acetobacterium, Alkalibacter, Anaerofustis, Pseudoramibacter, and possibly Garciella. The family Eubacteriaceae is then composed of Gram-stain-positive rods, which are frequently thin (~0.5 μm). Formation of endospores is rare. May be motile by a single flagellum or nonmotile. Obligately anaerobic, catalase-negative. Chemoorganotrophs, many of which ferment sugars and utilize proteinaceous nitrogen sources. Mesophilic to moderately thermophilic. Neutrophilic to alkaliphilic. Some species are halotolerant.
