Lentinus edodes and Pleurotus species from various origins were compared for the first time for their ability to produce lignocellulolytic enzyme in solid-state (SSF) and submerged (SF) fermentation of various plant raw material. Fungi cultivation in identical culture conditions revealed wide differences among both species and strains of the same species. The yields of CMCase (62.3Uml(-1)), xylanase (84.1 U ml(-1)), FPA (5.9 U ml(-1)), and laccase (4103 Ul(-1)) are the best so far obtained with the strains of oyster mushrooms. The study pointed out that the nature of lignocellulosic material and the method of fungi cultivation are factors determining the expression of lignocellulolytic potential of fungi as well as the ratio of individual enzymes in enzyme complex. SSF of tree leaves is favorable for laccase and MnP secretion by the majority L. edodes and Pleurotus strains, whereas SF provides better production of hydrolytic enzymes.
首次比较了不同来源的香菇和平菇在各种植物原料固态发酵(SSF)和深层发酵(SF)中产生木质纤维素酶的能力。在相同培养条件下对真菌进行培养,结果显示同一物种的不同菌株以及不同物种之间存在很大差异。目前,平菇菌株所获得的羧甲基纤维素酶(CMCase,62.3Uml⁻¹)、木聚糖酶(84.1Uml⁻¹)、滤纸酶活性(FPA,5.9Uml⁻¹)和漆酶(4103Ul⁻¹)产量是最高的。该研究指出,木质纤维素材料的性质和真菌培养方法是决定真菌木质纤维素分解潜力表达以及酶复合物中各酶比例的因素。大多数香菇和平菇菌株在树叶固态发酵中有利于漆酶和锰过氧化物酶的分泌,而深层发酵则更有利于水解酶的产生。
