Six facultatively anaerobic, non-motile lactic acid bacteria were isolated from spontaneous cocoa bean fermentations carried out in Brazil, Ecuador and Malaysia. Phylogenetic analysis revealed that one of these strains, designated M75(T), isolated from a Brazilian cocoa bean fermentation, had the highest 16S rRNA gene sequence similarity towards Weissella fabaria LMG 24289(T) (97.7%), W. ghanensis LMG 24286(T) (93.3 %) and W. beninensis LMG 25373(T) (93.4%). The remaining lactic acid bacteria isolates, represented by strain M622, showed the highest 16S rRNA gene sequence similarity towards the type strain of Fructobacillus tropaeoli (99.9 %), a recently described species isolated from a flower in South Africa. pheS gene sequence analysis indicated that the former strain represented a novel species, whereas pheS, rpoA and atpA gene sequence analysis indicated that the remaining five strains belonged to F. tropaeoli; these results were confirmed by DNA-DNA hybridization experiments towards their respective nearest phylogenetic neighbours. Additionally, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry proved successful for the identification of species of the genera Weissella and Fructobacillus and for the recognition of the novel species. We propose to classify strain M75(T) (=LMG 26217(T) =CCUG 61472(T)) as the type strain of the novel species Weissella fabalis sp. nov.
