Representative total ion chromatogram (TIC) of GC-MS showing the presence of 16 amino acids from the protein hydrolysates of Xanthomonas oryzae pv. oryzae BXO43 when fed with xylose and glucose. Each peak is marked in a single letter code corresponding to the time of elution for a particular amino acid, as follows: A-Alanine; G-Glycine; V-Valine; L-Leucine; I-Isoleucine; P-Proline; M-Methionine; S-Serine; T-Threonine; P-Phenylalanine; A-Aspartate; G-Glutamate; L-Lysine; A-Arginine; H-Histidine; and T-Tyrosine. Owing to the gram-negative nature of Xanthomonas, additional peaks in the chromatogram are considered to be the cell wall components, obtained when performing the acid hydrolysis of the harvested Xoo samples.
