Moorella caeni sp. nov., isolated from thermophilic anaerobic sludge from a methanol-fed reactor
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 rec-ommend that strain AMPT (DSM 21394T=JCM 35360T) should be classified as representing new species, for which we propose the name Moorella caeni sp. nov.
