Fig. 8From: Developing a single strain for in vitro salvage synthesis of NAD+ at high temperatures and its potential for bioconversionNAD+/NADH concentration. NAD+/NADH concentrations were measured every 8 h for 32 h with the enzyme cocktail (+ cocktail) or in the negative control (− cocktail). NAD+/NADH concentrations in the negative control were below the detection limit (< 1 µM). Error bars represent standard errors calculated from triplicate measurementsBack to article page
