The 'in vitro' activity of eight long-chain aliphatic aldehydes from olive flavor (hexanal, nonanal, (E)-2-hexenal, (E)-2-eptenal, (E)-2-octenal, (E)-2-nonenal, (E)-2-decenal and (E,E)-2,4-decadienal) against a number of standard and freshly isolated bacterial strains has been evaluated. The saturated aldehydes did not exhibit significant antibacterial activity, while the alpha,beta-unsaturated aldehydes showed a broad antimicrobial spectrum and similar activity against Gram-positive and Gram-negative bacteria. The activity of the aldehydes under investigation seems to depend not only on the presence of the alpha,beta-double bond, but also on the chain length from the enal group and on the strain tested.

Abstract
The 'in vitro' activity of eight long-chain aliphatic aldehydes from olive flavor (hexanal, nonanal, (E)-2-hexenal, (E)-2-eptenal, (E)-2-octenal, (E)-2-nonenal, (E)-2-decenal and (E,E)-2,4-decadienal) against a number of standard and freshly isolated bacterial strains has been evaluated. The saturated aldehydes did not exhibit significant antibacterial activity, while the alpha,beta-unsaturated aldehydes showed a broad antimicrobial spectrum and similar activity against Gram-positive and Gram-negative bacteria. The activity of the aldehydes under investigation seems to depend not only on the presence of the alpha,beta-double bond, but also on the chain length from the enal group and on the strain tested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
