| Abstract |
In 2014, Rahkila et al. transferred Leuconostoc gasicomitatum to Leuconostoc gelidum as L. gelidum subsp. gasicomitatum comb. nov. based on a 75 % DNA-DNA hybridization value. In the present study, the taxonomic status of L. gelidum subsp. gasicomitatum is re-evaluated by a polyphasic approach, including 16S rRNA, pheS, rpoA, recA, and atpA gene sequence analyses, phylogenomic treeing, analyses of ANI (average nucleotide identity) and dDDH (digital DNA-DNA hybridization), fatty acid methyl ester analysis and a phenotypic characterization. On the basis of the ANI and dDDH values, we propose to reject the proposal of Rahkila et al. to reclassify L. gasicomitatum as L. gelidum subsp. gasicomitatum.
