Catabolism of arylglycerol-beta-aryl ethers lignin model compounds by Pseudomonas cepacia 122.
Pseudomonas cepacia 122 can grow on several lignin model compounds including the arylglycerol-beta-aryl ethers guaiacylglycerol-beta-coniferyl ether and guaiacylglycerol-beta-guaiacyl ether. Non-phenolic lignin model compounds are not degraded by this bacterium. The enzyme system catalyzing guaiacylglycerol-beta-guaiacyl ether dissimilation in Pseudomonas cepacia 122 is inducible and repressed by glucose. Guaiacylglycerol and guaiacylglycerol-beta-guaiacyl ether were identified as intermediates in guaiacylglycerol-beta-coniferyl ether catabolism. Guaiacol, guaiacoxyethanol, vanillin and vanillic acid were identified as intermediates of guaiacylglycerol-beta-guaiacyl ether breakdown indicating that a C alpha-C beta splitting mechanism is involved in the degradation of aryl-alkyl ethers by this bacterium.
