Fig. 2From: Statistically optimized production and characterization of vanillin from creosol using newly isolated Klebsiella pneumoniae P27Simultaneous measurement of growth of K. pneumoniae P27 and vanillin production in the fermentation medium. Growth of K. pneumoniae P27 (●) and vanillin production (■) were measured at 660 nm and 340 nm, respectively. All values are expressed as mean ± SD (n = 3)Back to article page
