Abstract
This study presents MP1D12T (=NRRL B-67553T=NCTC 14480T), an isolate from the ruminal content of an Angus steer fed a high grain diet. Phenotypic and genotypic traits of the isolate were explored. MP1D12T was found to be a strictly anaerobic, catalase-negative, oxidase-negative, coccoid bacterium that frequently grows in chains. Analysis of metabolic products as a result of carbohydrate fermentation showed succinic acid as the major organic acid produced with lactic acid and acetic acid as minor products. Phylogenetic analysis of MP1D12T based on 16S rRNA nucleotide sequence and amino acid sequences from the whole genome presents a divergent lineage from other members in the family Lachnospiraceae. 16S rRNA sequence comparison, whole genome average nucleotide identity digital DNA-DNA hybridization and average amino acid identity results suggest that MP1D12T represents a novel species in a novel genus within the family Lachnospiraceae. We propose the creation of the genus Chordicoccus in which MP1D12T represents the type strain for the novel species Chordicoccus furentiruminis.
