This study investigates the metabolic responses of Auricularia cornea when cultured on de-oiled leaves of Cinnamomum longepaniculatum (DeCL), an underutilized waste product. The metabolic profiles of A. cornea cultured with four different quality ratios of DeCL substrate (0 %, 14 %, 28 % and 42 %) were analyzed by UHPLC-MS/MS-based metabolomics. A total of 516 metabolites were identified and classified into 78 categories, with phenols, alkaloids and flavonoids accounting for 26.7 % of the total. In addition, 32 metabolite biomarkers associated with eight major metabolic pathways were identified. This pioneering research provides valuable insights into the utilization of DeCL, and expands our knowledge of the metabolic dynamics underlying the growth of A. cornea on alternative substrates.
本研究调查了在肉桂叶（DeCL）下脚料（一种未充分利用的废物）上培养的银耳的代谢反应。采用 UHPLC-MS/MS 代谢组学分析了在四种不同质量比的 DeCL 基质（0%、14%、28%和 42%）中培养的银耳的代谢谱。共鉴定出 516 种代谢物，并分为 78 类，其中酚类、生物碱和类黄酮占总量的 26.7%。此外，还鉴定出与 8 条主要代谢途径相关的 32 种代谢物生物标志物。这项开拓性的研究为 DeCL 的利用提供了有价值的见解，并扩展了我们对银耳在替代基质上生长的代谢动态的认识。
