4-dimethoxycinnamic acid in shaking and nitrogen sufficient cultures. Metabolites identified included 3-(3,4-dimethoxyphenyl)propionic acid, dimethoxycinnamyl alcohol and 3-(3,4-dimethoxyphenyl)- 1-propanol. Significantly smaller amounts of veratryl and vanillyl alcohol were also present. The abundance of the propionic acid and the propanol as metabolic products indicate that olefin saturation and acid reduction
摘要 白腐真菌 Phanerochaete chrysosporium 在振荡和氮充足的培养物中代谢 3,4-二甲氧基肉桂酸。鉴定的代谢物包括3-(3,4-二甲氧基苯基)丙酸、二甲氧基肉桂醇和3-(3,4-二甲氧基苯基)-1-丙醇。还存在显着较少量的藜芦醇和香草醇。大量的丙酸和丙醇作为代谢产物表明烯烃饱和和酸还原是在这些条件下催化的重要反应。从 3-(3,4-二甲氧基苯基)-丙酸代谢中鉴定的代谢物包括上述 1-丙醇以及藜芦醇和香草醇;这些苯甲醇衍生物作为代谢物的鉴定表明,α,
