From: Vanillin production by biotransformation of phenolic compounds in fungus, Aspergillus luchuensis
Total ion chromatogram obtained from the biotransformation of phenolic compounds in Aspergillus luchuensis. The total ion chromatogram (TIC) was measured by LC/MS. Each TIC mass spectrum for a ferulic acid ((M-H)−, 193.2), b vanillin ((M-H)−, 151.2), c vanillic acid ((M-H)−, 167.1), d vanillin glucoside ((M-H)−, 313.3) and individual retention times were identical to those of the authentic compounds
