Application

Application	Comment	Organism
biotechnology	production of tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate, an important chiral intermediate for the synthesis of rosuvastatin, using carbonyl reductase coupled with glucose dehydrogenase. A recombinant Escherichia coli strain harboring carbonyl reductase R9M and glucose dehydrogenase is constructed with high carbonyl reduction activity and cofactor regeneration efficiency. The recombinant Escherichia coli cells are applied for the efficient production of tert-butyl (3R,5S)-6-chloro-3,5-dihydroxyhexanoate with a substrate conversion of 98.8%, a yield of 95.6% and an enantiomeric excess of more than 99.0% under 350 g/l of tert-butyl (S)-6-chloro-5-hydroxy-3-oxohexanoate after 12 h reaction. A substrate fed-batch strategy is further employed to increase the substrate concentration to 400 g/l resulting in an enhanced product yield to 98.5% after 12 h reaction in a 1 l bioreactor. Meanwhile, the space-time yield is 1182.3 g/l*day	Exiguobacterium sibiricum
