This PhD research project was focused on innovative biotechnological production and recovery of vanillin and vanillin precursors. Experiments carried out using whole cells or crude enzyme preaparations demonstrated that: selective recovery of the product, using macroporous resins, enhances the biological conversion of ferulic acid to vanillin using resting cells of Escherichia coli FR13 strain; (b) thermal pre-treatment at 55°C of crude PVA acylase from Streptomyces mobaraensis DSM40847 improves the conversion of capsaicin to vanillylamine
