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.
洋葱伯克霍尔德菌122能够在几种木质素模型化合物上生长,包括芳基甘油-β-芳基醚愈创木基甘油-β-松柏基醚和愈创木基甘油-β-愈创木基醚。非酚类木质素模型化合物不能被这种细菌降解。在洋葱伯克霍尔德菌122中催化愈创木基甘油-β-愈创木基醚异化作用的酶系统是可诱导的,且受葡萄糖抑制。愈创木基甘油和愈创木基甘油-β-愈创木基醚被鉴定为愈创木基甘油-β-松柏基醚分解代谢的中间产物。愈创木酚、愈创木氧基乙醇、香草醛和香草酸被鉴定为愈创木基甘油-β-愈创木基醚分解的中间产物,这表明该细菌降解芳基-烷基醚涉及一种Cα-Cβ裂解机制。
