Abstract

Abstract Val.li.ta'le.a. L. gen. fem. n. vallis, a valley, vale; L. fem. N. talea, a rod; N.L. fem. n. Vallitalea , a rod isolated from a vale. Firmicutes / Clostridia / Clostridiales / Vallitaleaceae / Vallitalea The genus Vallitalea at the time of writing, comprises three species with validly published names, Vallitalea guaymasensis , which was isolated from sediments of Guaymas Basin, Vallitalea okinawensis , isolated from Okinawa Trough sediment, and Vallitalea pronyensis , obtained from a shallow submarine hydrothermal field in Prony Bay in the south of New Caledonia. The species of the genus are thermotolerant or mesophilic, moderately halophilic and strictly anaerobic, and they present a fermentative growth on some carbohydrates. Phylogenetic analyses using 16S rRNA gene sequences placed the three species as belonging to the phylum Firmicutes , class Clostridia , order Clostridiales, family Vallitaleaceae . DNA G + C content (mol%) : 31.2. Type species : Vallitalea guaymasensis Lakhal et al. 2013 VP .
