摘要： 淀粉是高等植物中储量最丰富的可再生碳水化合物之一。在食品加工业中可以用来生产许多有价值的食品。此外，淀粉也是发酵工业生产增值产品的重要原料。农林废弃物等木质纤维素材料通过生化转化过程被认为是生物能源生产的可再生原料。将木质纤维素生物质转化为燃料和化学品需要对生物质进行物理化学预处理，然后将纤维素和半纤维素等多糖成分酶解为单糖。这些糖可以进一步发酵成其他所需的化合物。解构过程中，由于木质纤维素部分过度降解，释放出多种抑制化合物，从而抑制发酵菌株的细胞生长和代谢能力。大量的废纸等纤维素材料也可以作为潜在的廉价原料，用于可持续生产增值产品。目前的研究主要集中于淀粉水解物（小麦、马铃薯、水稻）和木质纤维素水解物（甘蔗渣、麦秸）在液体发酵纤维素酶生产中的应用。它还描述了纤维素水解产物（废报纸）在产品形成中的潜力。

Abstract: Starch is one of the most abundant renewable carbohydrate reserves of higher plants. It can be used to produce many valuable food products in the food processing industry. Furthermore, starch is also used as an important feedstock in the fermentation industry to produce value-added products. Lignocellulosic materials such as agriculture and forestry wastes are considered as a renewable feedstock for bioenergy production through a biochemical conversion process. Converting lignocellulosic biomass into fuels and chemicals entail a physicochemical pretreatment of the biomass, followed by enzymatic hydrolysis of the polysaccharide components such as cellulose and hemicellulose into monomeric sugars. These sugars can then be further fermented into other desired compounds of interest. During the deconstruction processes, various inhibitory compounds are released due to the partial over-degradation of lignocellulose biomass, which inhibits the cell growth and metabolic capacity of fermenting strains. Cellulosic materials such as waste paper in large quantities can also be used as potentially cheap feedstock for sustainable production of value-added products. The present investigation is mainly focused on the utility of starchy hydrolysates (wheat, potato, and rice) and lignocellulosics hydrolysates (bagasse and wheat straw) in cellulase production under liquid state fermentation. It also depicts the potential of cellulosic hydrolysate (waste newspaper) in product formation.
Key words: Starch hydrolysate    Bagasse hydrolysate    Wheat straw hydrolysate    Waste newspaper hydrolysate    Cellulases
