title: Description of Trichococcus ilyis sp. nov. by combined physiological and in silico genome hybridization analyses.
abstract: Species of the genus Trichococcus share high similarity of their 16S rRNA gene sequences (>99 %). Digital DNA-DNA hybridization values (dDDH) among type strains of all described species of the genus Trichococcus (T. flocculiformis DSM 2094T, T. pasteurii DSM 2381T, T. collinsii DSM 14526T, T. palustris DSM 9172T, and T. patagoniensisDSM 18806T) indicated that Trichococcus sp. strain R210T represents a novel species of the genus Trichococcus. The dDDH values showed a low DNA relatedness between strain R210T and all other species of the genus Trichococcus (23-32%). Cells of strain R210T were motile, slightly curved rods, 0.63-1.40×0.48-0.90 µm and stained Gram-positive. Growth was optimal at pH 7.8 and at temperature of 30 °C. Strain R210T could utilize several carbohydrates, and the main products from glucose fermentation were lactate, acetate, formate and ethanol. The genomic DNA G+C content of strain R210T was 47.9 mol%. Based on morphological, physiological and biochemical characteristics along with measured dDDH values for all species of the genus Trichococcus, it is suggested that strain R210T represents a novel species within the genus Trichococcus, for which the name Trichococcus ilyis sp. nov. is proposed. The type strain is R210T (=DSM 22150T=JCM 31247T).
