fermenting cherry juice and broccoli puree, Lactobacillus spp. exhibited strain-specific metabolism of
phenolic acid derivatives. The metabolism of protocatechuic, caffeic and p-coumaric acids through
phenolic acid decarboxylases and reductases differed between mMRS and cherry juice and broccoli
puree. The synthesis of reduced compounds was the highest during food fermentations and the substrate
seemed to modulate the metabolism of phenolic compounds. The reduction of phenolic acids involves a
hydrogen donor and the re-oxidation of the reduced co-factor NADH, which may provide a metabolic
advantage through NADþ regeneration. Quinic acid reduction may replace fructose and pyruvate as
hydrogen acceptors, and it may provide an energetic advantage to heterofermentative bacteria when
growing in broccoli puree lacking of fructose. This study demonstrated that phenolics metabolism may
confer a selective advantage for lactobacilli in vegetable and fruit fermentation, and the metabolic routes
are strongly dependent on the intrinsic factors of substrate. Fermented cherry juice and broccoli puree,
due to the selected bacterial bioconversion pathways, are enriched in phenolic derivative with high
human bioavailability and biological activity.
