Companilactobacillus salsicarnum Zheng et al. 2020 is a later heterotypic synonym of Companilactobacillus mishanensis (Wei and Gu 2019) Zheng et al. 2020.

Abstract

Lactobacillus mishanensis was isolated from Chinese traditional pickle, and validly published in October 2019. Lactobacillus salsicarnum was isolated from salami products in Germany, and effectively described in November 2019. In the reclassification of the genus Lactobacillus by Zheng et al. in April 2020, L. mishanensis was transferred to Companilactobacillus as Companilactobacillus mishanensis comb. nov., and Companilactobacillus salsicarnum was proposed as a novel species. In the present study, the relationship between C. mishanensis and C. salsicarnum was evaluated. The type strains of C. mishanensis and C. salsicarnum shared 100 % 16S rRNA gene sequence similarity, 100 % pheS sequence similarity, 99.9 % rpoA sequence similarity, a 99.9 % average nucleotide identity value and a 99.5 % digital DNA-DNA hybridization value, indicating that they represent the same species. On the basis of the results presented here, we propose C. salsicarnum [Zheng et al. 2020] as a later heterotypic synonym of C. mishanensis (Wei and Gu 2019) [Zheng et al. 2020].
