Stereoselective reduction of keto esters: thermophilic bacteria and microalgae as new biocatalysts

This review covers the possibility of aerobic thermophilic bacteria (Bacillus strains and thermophilic actinomycetes) and microalgae (Chlorella strains and marine algae) as new biocatalysts for the stereoselective reduction of α- and β-keto esters. The mechanistic interpretation of the reduction by a thermophilic actinomycete is also delineated.
