Abstract
Catenulispora acidiphila Busti et al. 2006 is the type species of the genus Catenulispora, and is of interest because of the rather isolated phylogenetic location it occupies within the scarcely explored suborder Catenulisporineae of the order Actinomycetales. C. acidiphilia is known for its acidophilic, aerobic lifestyle, but can also grow scantly under anaerobic condi-tions. Under regular conditions, C. acidiphilia grows in long filaments of relatively short aerial hyphae with marked septation. It is a free living, non motile, Gram-positive bacterium iso-lated from a forest soil sample taken from a wooded area in Gerenzano, Italy. Here we de-scribe the features of this organism, together with the complete genome sequence and anno-tation. This is the first complete genome sequence of the actinobacterial family Catenulispo-raceae, and the 10,467,782 bp long single replicon genome with its 9056 protein-coding and 69 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
