For a chart and in depth discussion on what types of sugars are fermentable by different species of ''Lactobaccilus'', as well as charts on ''secondary metabolites'', see [http://phdinbeer.com/2015/04/13/physiology-of-flavors-in-beer-lactobacillus-species/ Matt Humbard's ''Physiology of Flavors in Beer – Lactobacillus Species'' blog article].
