After 3 days of biotransformation, the work-up procedure followed by bulb-to-bulb distillation afforded 190 mg of a pale yellow oil containing p-anisaldehyde (91%), p-anisic acid (4%) and unidentified compounds (5%). Acidification and extraction of the biotransformation broth afforded 80 mg of anisic acid. Yield of p-anisaldehyde vs transformed p-anisic acid is 64%, and absolute yield 51%.
