At 5 g/l, ferulic acid, a plant cell-wall phenolic, severely repressed growth of the lignocellulose-degrading fungi Trichoderma harzianum, Chaetomium cellulolyticum, Phanaerochaete chrysosporium, Trametes versicolor and Pleurotus sajor-caju. At 0.5 g/l, howerver, it slightly stimulated growth of the latter two organisms. Two classes of extracellular enzymes involved in cellulose and glycolignin breakdown were assayed: cellulases; and phenol oxidases as laccases. All of the strains depolymerized cellulose but two (T. versicolor and P. sajor-caju) also secreted laccases. Laccase-secreting fungal species had normal levels of cellulose saccharification except in the presence of 5 g ferulic acid/l, whereas saccharification by the other strains was suppressed at all concentrations of the phenolic tested.
在 5g/L 时，阿魏酸（一种植物细胞壁酚类物质）严重抑制了木质纤维素降解真菌里氏木霉、纤维素分解真菌嗜热毛壳菌、黄孢原毛平革菌、栓菌和糙皮侧耳的生长。然而，在 0.5g/L 时，它略微刺激了后两种生物的生长。测定了参与纤维素和甘油木质素分解的两类细胞外酶：纤维素酶和酚氧化酶如漆酶。所有菌株都能解聚纤维素，但有两种（栓菌和糙皮侧耳）也分泌漆酶。除了在 5g/L 阿魏酸存在的情况下，分泌漆酶的真菌物种的纤维素糖化水平正常，而其他菌株在测试的酚类物质的所有浓度下的糖化都受到抑制。
