The fungi Botrytis cinerea and Colletotrichum acutatum were used to convert acetophenone to 1-phenylethanol. B. cinerea produced a 98.5% yield of 1-phenylethanol with an enantiomeric excess of 93.8%. Conversely, addition of 1-phenylethanol did not change the reaction rate or product composition. In contrast, the reaction catalyzed by C. acutatum was markedly slower, commencing only after an approximately three-day delay. The concentration of substrate decreased gradually over approximately 14 days, coinciding with increased production of 1-phenylethanol. Phenol was produced after 18 days, and the final yields of 1-phenylethanol and phenol were 38.1% and 61.5%, respectively.
