In order to utilize phenolic compounds in unused biomass resources, the metabolic pathway of ferulic acid by way of a white-rot fungus, Schizophyllum commune, was investigated. Ferulic acid was immediately degraded, and the formation of 4-vinyl guaiacol was confirmed by GC-MS analysis. The metabolic test of ferulic acid and its degradation products indicated that S. commune converted ferulic acid into 4-vinyl guaiacol by decarboxylation. This was then oxidized to vanillin and vanillic acid. This result indicates that S. commune distinguished ferulic acid from lignins and metabolized it specifically.
为了利用未利用生物质资源中的酚类化合物，研究了裂褶菌对阿魏酸的代谢途径。阿魏酸立即被降解，通过气相色谱-质谱联用（GC-MS）分析证实了4-乙烯基愈创木酚的形成。阿魏酸及其降解产物的代谢试验表明，裂褶菌通过脱羧作用将阿魏酸转化为4-乙烯基愈创木酚。然后将其氧化为香草醛和香草酸。该结果表明，裂褶菌能够区分阿魏酸和木质素，并对其进行特异性代谢。
