A process for producing (-)-substituted styrene oxide efficiently, which comprises reducing 2-bromo-1-(3'-chlorophenyl)ethanone asymmetrically into (-)-2-bromo-1-(3'-chlorophenyl)ethanol in the presence of a microorganism belonging to any of the 11 genera including Ashbya and Brettanomyces, and cyclizing the isolated and purified product under an alkaline condition into (-)-substituted styrene oxide.
