Abstract
Strain AMPT has been previously suggested as a strain of the species
Moorella thermoacetica
Jiang et al. 2009 (based on the high 16S rRNA gene identity, 98.3 %). However, genome-based phylogenetic analysis of strain AMPT reveals that this bacterium is in fact a novel species of the genus
Moorella
. Genome relatedness indices between strain AMPT and
Moorella thermoacetica
DSM 521T were below the minimum threshold values required to consider them members of the same species (digital DNA–DNA hybridization, 52.2 % (<70%); average nucleotide identity, 93.2 % (<95%)). Based on phylogenetic and phenotypic results we recommend that strain AMPT (DSM 21394T=JCM 35360T) should be classified as representing new species, for which we propose the name Moorella caeni sp. nov.
