Rhodotorula sp. LSL, isolated from a local landfarming was able to catalyze the reduction of prochiral arylketones into sec-alcohols with excellent Prelog stereoselectivity (ee >99%). The use of resting and lyophilized cells was optimized accessing to an easy-to-use whole cell biocatalyst that efficiently works even under non-sterile conditions, without the addition of external cofactors and using plain water as solvent. The catalyst resistance in alkaline media enabled (chemo)enzymatic one-pot procedures at high pH values. So a simple and efficient methodology was applied to prepare alternatively enantiopure β-halohydrins, terminal diols and epoxides from aromatic α-haloketones
