Resumen:
The influence of phenolic compounds on the growth of Lactobacillus hilgardii X1B
and putrescine formation was assayed at concentrations normally present in
wine. Agmatine degradation increased growth and survival of the microorganism
and the alkalinity of the media. Bacterial growth was stimulated by phenolic
compounds, except for gallic acid and quercetin. Putrescine formation from
agmatine diminished in the presence of protocatechuic, vanillic and caffeic
acids, and the flavonoids catechin and rutin. The concentration of phenolic
compounds decreased after five days of incubation of L hilgardii X1B, except for gallic acid and quercetin.
The results indicate that phenolic compounds, besides their already known
beneficial properties to human health, seem to be a natural way of diminishing
putrescine formation.
