Chiral alcohols are key intermediates in the synthesis of pharmaceutical, agrochemical, and other fine chemicals. Sulfatase can catalyze the hydrolytic cleavage of sulfate esters by liberating inorganic sulfate and the corresponding secondary alcohol. In this review,microbial sources,catalytic mechanisms, and applications of sulfatase were summarized. Moreover, methods for improving catalytic stability by immobilization and enhancing selectivity by addition of metal ions or organic cosolvents were introduced.
