Currently, the biotechnological preparation of fragrances using natural materials attracted growing attention. Enzymatic synthesis of vanillin from isoeugenol by recombinant isoeugenol monooxygenase from Pseudomonas nitroreducens Jin1 was systematically investigated herein. With series of work on the construction of recombinant E.

Isomerization of eugenol to isoeugenol
Reaction Kinetics and Catalysis Letters, 1987The isomerization of eugenol to isoeugenol was investigated by employing catalysis by KOH in amyl alcohol or glycerol, or by RhCl3. A number of factors which affect the reaction (solvent, temperature, molar ratios, presence of water) were examined.

ABSTRACTThe influence of 5 liquid, 6 cosmetic and 2 ointment vehicles on the penetration of benzyl alcohol, isoeugenol and methyl isoeugenol through human epidermis was studied. Benzyl alcohol penetrated most rapidly from almost all vehicles. Among liquid vehicles, liquid paraffin provided the best penetration for the 3 compounds. As the ratio of water

Studies on the Photodimerization of Isoeugenol
Journal of the Chinese Chemical Society, 1978AbstractUnder the irradiation of the ultraviolet light, Isoeugenol (I) undergoes dimerization in acetone to give diisoeugenol (II) and dehydrodiisoeugenol (III). The structures are determined by the comparison of the mixed m. p., I. R. spectra and T. L. C. with synthesized authentic samples. Also the photoreaction mechanism is discussed in detail.

For efficiently enhancing the activity of isoeugenol monooxygenase, a whole cell overproducing active aggregate IEM720-18A was successfully fabricated via the fusion of amphiphilic short peptide 18A (EWLKAFYEKVLEKLKELF) and isoeugenol monooxygenase and then efficiently expressed in E. coli BL21 (DE3). Such resulting bacteria, E.

Pseudomonas putida I58 was isolated from soil by a conventional enrichment culture method using isoeugenol as a sole carbon source. The strain utilized isoeugenol, vanillin and vanillic acid as carbon sources. On the other hand, the intermediates of the eugenol-degrading pathway, such as eugenol, coniferyl alcohol, coniferyl aldehyde and ferulic acid ...

Oxidation of isoeugenol by Nocardia iowensis
Enzyme and Microbial Technology, 2008Abstract Isoeugenol is a starting material for both the synthetic and biotechnological production of vanillin and vanillic acid. Nocardia iowensis DSM 45197 (formerly Nocardia species NRRL 5646) resting cells catalyze the conversion of isoeugenol to vanillic acid, vanillin, vanillyl alcohol and guaiacol.

Enhancing the antibacterial efficacy of isoeugenol by emulsion encapsulation
International Journal of Food Microbiology, 2016Food spoilage and foodborne illnesses are two global challenges for food manufacturers. Essential oils are natural antibacterials that could have a potential for use in food preservation. Unfortunately high concentrations are needed to obtain the desired antibacterial effect, and this limits their use in food due to their adverse organoleptic ...
