part of detectable sphagnum acid is buffer-soluble, as well as in Sphagnum collected from natural sites and in Sphagnum cultivated in bioreactors. Cultivating Sphagnum species in bioreactors under axenic conditions leads to an enhancement of the buffer-soluble part of all analysed phenolics with a concomitant decrease of their cell wall-bound amount. Sphagnum acid, sphagnum acid ethyl ester, hydroxybutenolide
摘要 [ E ]-4-乙氧基羰基-3-(4′-羟基苯基)-but-2-en-1-羧酸(反式-泥炭酸乙酯)和对羟基苯乙酮从泥炭藓细胞壁的乙醇提取物中分离出来。 [Z]-3-(4'-羟基苯基)-pent-2-en-1,5-二羧酸(顺式-泥炭酸)来自经辐照的反式-泥炭酸溶液。这些化合物的结构通过核磁共振光谱法阐明。区室化研究表明,可检测到的泥炭藓酸的主要部分是缓冲液可溶性的,从天然地点收集的泥炭藓和在生物反应器中培养的泥炭藓中也是如此。在无菌条件下在生物反应器中培养泥炭藓物种会导致所有分析的酚类物质的缓冲液可溶部分增加,同时它们的细胞壁结合量也随之减少。泥炭酸,泥炭酸乙酯、羟基丁烯内酯、对羟基苯甲酸、对香豆酸和t-肉桂酸也显着排泄到S.fallax和S.cuspidatum的流出培养基中。假定了用于储存内源性游离水溶性酚类物质的特定隔室。
