Lignocellulose, the main component of plant cell walls, comprises polyaromatic lignin and fermentable materials, cellulose and hemicellulose. It is a plentiful and renewable feedstock for chemicals and energy. It can serve as a raw material for the production of various value-added products, including cellulase and xylanase. Cellulase is essentially required in lignocellulose-based biorefineries and is applied in many commercial processes. Likewise, xylanases are industrially important enzymes applied in papermaking and in the manufacture of prebiotics and pharmaceuticals. Owing to the widespread application of these enzymes, many prokaryotes and eukaryotes have been exploited to produce cellulase and xylanases in good yields, yet yeasts have rarely been explored for their plant-cell-wall-degrading activities. This review is focused on summarizing reports about cellulolytic and xylanolytic yeasts, their properties, and their biotechnological applications.
木质纤维素是植物细胞壁的主要成分，包括多芳香族木质素和可发酵的物质，如纤维素和半纤维素。它是化学品和能源的丰富可再生原料。它可以作为生产各种高附加值产品的原料，包括纤维素酶和木聚糖酶。纤维素酶在木质纤维素为基础的生物炼制厂中是必不可少的，并且应用于许多商业过程中。同样，木聚糖酶是工业上重要的酶，应用于造纸以及生产益生菌和药物。由于这些酶的广泛应用，许多原核生物和真核生物已经被开发用于生产高产量的纤维素酶和木聚糖酶，但酵母在植物细胞壁降解活性方面很少被探索。本综述重点总结了关于纤维素分解酵母和木聚糖分解酵母、它们的特性以及它们的生物技术应用的报告。
