Degradation of non-phenolic beta-o-4 lignin substructure model compounds by Acinetobacter sp.
Acinetobacter sp. utilized non-phenolic beta-o-4-model compounds, 2-methoxy-4-formylphenoxyacetic acid and veratrylglycerol-beta-guaiacyl ether (VGE) as sole carbon source. Vanillin, vanillic acid, protocatechuic acid and catechol were detected in the 2-methoxy-4-formylphenoxyacetic acid amended culture. Veratryl alcohol, veratraldehyde, veratric acid, vanillic acid, protocatechuic acid, catechol and guaiacol were identified from veratrylglycerol-beta-guaiacyl ether culture. Acinetobacter sp. produced catechol 1,2-dioxygenase and protocatechuate 3,4-dioxygenase that cleaved catechol and protocatechuic acid, respectively.
