Fig. 2From: Constitutive glucose dehydrogenase elevates intracellular NADPH levels and luciferase luminescence in Bacillus subtilisIntracellular levels of NADPH in 168 and KW012. Strains 168 and KW012 were grown for 24 h, and the cells were harvested to determine the intracellular levels of NADPH. The experiments were repeated three times; similar results were obtained and the results are presented as mean values ± SD (**, p < 0.01)Back to article page
