Lactobacillus ghanensis sp. nov., a motile lactic acid bacterium isolated from Ghanaian cocoa fermentations (original) (raw)
Abstract
Three Gram-positive, catalase-negative, motile, rod-shaped strains, designated L486, L489T and L499, were isolated from fermenting cocoa. These organisms produced dl-lactic acid from glucose without gas formation. Ammonia was not produced from arginine. Acid was produced from amygdalin, d-cellobiose, aesculin, d-fructose, d-glucose, d-galactose, d-mannitol, d-mannose, N-acetylglucosamine, l-rhamnose, sucrose, salicin and d-trehalose. The cell walls contained peptidoglycan of the d-meso-diaminopimelic acid type. A 16S rRNA gene sequence analysis revealed that the isolates belong phylogenetically to the genus Lactobacillus and are closely related to Lactobacillus nagelii, Lactobacillus vini and Lactobacillus satsumensis. Low DNA–DNA reassociation values were obtained between the isolates and the phylogenetically closest neighbours. On the basis of the genetic and phenotypic results, the isolates are considered to represent a novel species, for which the name Lactobacillus ghanensis is proposed. The type strain is L489T (=DSM 18630T=CCUG 53453T).
