Fig. 5From: Statistically optimized production and characterization of vanillin from creosol using newly isolated Klebsiella pneumoniae P27Identification of vanillin. A high-resolution mass spectrometry (HRMS) spectrum obtained by a Bruker Impact HD (Impact II-UHR-ESI-Q-ToF) mass spectrometer shows that the molecular ion at m/z 153.05 [M+H] corresponds to vanillin (molecular formula C8H9O3)Back to article page
