Lactobacillus fabifermentans sp. nov. and Lactobacillus cacaonum sp. nov., isolated from Ghanaian cocoa fermentations.

Two Gram-positive bacterial strains, LMG 24284T and LMG 24285T, were isolated from different spontaneous cocoa bean heap fermentations in Ghana. Analysis of their 16S rRNA gene sequences indicated that they were members of the Lactobacillus plantarum and Lactobacillus salivarius species groups, respectively. DNA-DNA hybridization experiments with their nearest phylogenetic neighbours demonstrated that both strains represented novel species that could be differentiated from their nearest neighbours by pheS sequence analysis, whole-cell protein electrophoresis, fluorescent amplified fragment length polymorphism analysis and biochemical characterization. Therefore, two novel Lactobacillus species are proposed, Lactobacillus fabifermentans sp. nov. (type strain LMG 24284T =DSM 21115T) and Lactobacillus cacaonum sp. nov. (type strain LMG 24285T =DSM 21116T).
