Carbonic Acid from Decarboxylation by “Malic” Enzyme in Lactic Acid Bacteria

Decarboxylation of substituted cinnamic acids by lactic acid bacteria isolated during malt whisky fermentation.

Seven strains of Lactobacillus isolated from malt whisky fermentations and representing Lactobacillus brevis, L. crispatus, L. fermentum, L. hilgardii, L. paracasei, L. pentosus, and L. plantarum contained genes for hydroxycinnamic acid (p-coumaric acid) decarboxylase. With the exception of L. hilgardii, these bacteria decarboxylated p-coumaric acid and/or ferulic acid, with the production of 4...

Lactic Acid Bacteria

Lactic acid bacteria comprise an ecologically diverse group of microorganisms united by formation of lactic acid as the primary metabolite of sugar metabolism (Davis et al., 1985b; 1988; Lonvaud-Funel, 1999; Carr et al., 2002; Liu, 2002). These bacteria utilize sugars by either homoor heterofermentative pathways (Section 2.4.1) as well as l-malic acid, a major acid present in grape must (Sectio...
