Fig. 5From: pH regulatory divergent point for the selective bio-oxidation of primary diols during resting cell catalysisWhole-cell catalysis of 1,5-PG by G. oxydans with pH control at 5.5. A: SOS technology, the symbols indicated the concentration of 1,5-PG (■), accumulated 5-HVA content (●), accumulated GTA content (▲) and the dotted line represented the DO level. B: cell recycling technology, the symbols indicated the accumulation of 5-HVA (■) and the columns represented the 5-HVA production achieved in each roundBack to article page
