SOLIS OBA, Aida et al. Biocatalytic reduction of benzaldehyde using vegetable wastes as enzyme sources. Acta univ [online]. 2017, vol.27, n.4, pp.13-18. ISSN 2007-9621.  https://doi.org/10.15174/au.2017.1284.

The aqueous extracts of the following vegetable wastes were used as an enzyme source to reduce benzaldehyde to benzyl alcohol: capulin, mamey, green pepper, chili, and avocado seeds; bean, turnip rape, fava bean, lima bean, and jinicuil pods; papaya peel, and chive leaves. The highest conversions of benzaldehyde were obtained with the capulin and mamey seeds, bean pods and chive leaves (86%, 77%, 54%, and 45% of benzyl alcohol respectively). The biocatalytic methodology proposed avoids the generation of chemical toxic waste because metallic reducing agents are used in the chemical reduction; and the biological residues can be used as fertilizers. This procedure complies with some of the principles of green chemistry.

Keywords : Benzaldehyde; benzyl alcohol; biocatalytic reduction; vegetable waste.
