| Common Name | Alpha-Pinene-oxide |
|---|
| Description | Alpha-pinene oxide is cheap monoterpene, which is important compound for the fragnance industry. Biocatalytic method is used to convert monoterpenes into terpenoids. The biotransformation of alpha-pinene oxide using resting cells of Pseudomonas fluorescens NCIMB 11671 produces isonovalal (cis-2-methyl-5-isopropylhexa-2,5-dienal), which is a fragrance. However, this biotransformation has technical problems including the following: alpha-pinene oxide undergoes autoxidation in water and light; it is hydrophobic and relatively toxic to the biocatalyst; and it suffers from product inhibition. the influence of other terpene byproducts on the flux of alpha-pinene oxide was investigated and found to decrease the flux into the organic phase by up to 10%.
