In this context, it supports suggestions of early researchers (e.g., Barel,
1998 cited in De Vuyst et al., 2010; Nicholls, 1913) that these bacteria are probably not essential for successful cocoa bean fermentations. Further
studies of cocoa fermentations under controlled conditions using
inoculated starter cultures of particular species of LAB are needed to
confirm this possibility. While the potential impact of LAB on the process
and bean quality through modulation of acidity and pH is not in
question, our data suggest the need for further research to better understand
the roles of other microbial groups, such as yeasts, in this context
and to better understand the biochemical reactionswithin the bean nib
that affect their organic acid content.
