Fig. 2From: Immobilization of engineered E. coli cells for asymmetric reduction of methyl acetoacetate to methyl-(R)-3-hydroxybutyrateThermal stability of free (a) and alginate-immobilized (b) recombinant E. coli cells. Reaction conditions: 4 mL Tris–HCl buffer (200 mM, pH 7.0), 100 mM MAA, 150 mM glucose, 30 mg/mL of free recombinant E. coli cells (wet weight), or alginate-immobilized cells containing the same amount of free cells, 40 °C, 200 rpmBack to article page
