The main goal of this project is the development of a novel solid substrate fermentation process for the bioconversion of agricultural residues into animal feed. The novel technology consists of the sequential application of aerobic fungal fermentation and anaerobic lactic acid fermentation or ensiling. The fungal fermentation by a mixed culture of host fungi will produce an enzyme complex well adapted for partially degrading the host plant cell wall into fermentable sugars, which in turn will be used by the lactic acid bacteria for efficient ensiling. During ensiling, the lactic acid preserves the substrate and catalyzes the hydrolysis of lignocellulose by the fungal enzymes obtained in the aerobic phase. This project will concentrate on elucidating the microbiological and enzymatic interactions in this mixed culture fermentation process, which may be an appropriate technology for the on-farm utilization of agricultural, range, and forestry residues, and which may also contribute to the realization of sustainable agriculture.

该项目的主要目标是开发一种新的固体基质发酵工艺，用于将农业残渣生物转化为动物饲料。新工艺由好氧真菌发酵和厌氧乳酸发酵顺序应用组成。青贮酒。由寄主真菌混合培养的真菌发酵将产生一种酶复合体，适合于将寄主植物细胞壁部分降解为可发酵糖，然后，乳酸菌将利用这些蛋白质进行有效的青贮。在青贮期，乳酸保护底物，并通过在好氧条件下获得的真菌酶催化木质纤维素的水解。阶段。本项目将致力于阐明混合培养发酵过程中的微生物和酶的相互作用，这可能是一种适合于农场利用农业、牧场和林业残留物的技术，这也可能有助于实现可持续农业。
