Xylan is a polysaccharide of industrial interest and its solubilization demands a high quantity of chemicals. A combination of chemical and biological treatment was applied to solubilize xylan, reducing hydrogen peroxide charge. Coniophora puteana, Gloeophyllum trabeum, and Pleurotus ostreatus were grown on non-milled sugarcane bagasse up to four months. After microorganisms growth, the chemical solubilization of xylan was performed applying 3% and 6% (m/v) of hydrogen peroxide. Using 3% of hydrogen peroxide after the biological pretreatment resulted in 99.74% of the xylan solubilization after the fourth month to C. puteana growth, and 48.63% of the xylan solubilized after the first month to G. trabeum growth. The results demonstrated that the biological pretreatment reduced the recalcitrance of the sugarcane bagasse by changing its structure, allowing to solubilize a higher amount of xylan, and applying half of the chemical reagent contributing to process feasibility.

木聚糖是工业上感兴趣的多糖，其溶解需要大量的化学物质。结合化学和生物处理以溶解木聚糖，减少过氧化氢的电荷。Coniophora puteana，Gloeophyllum trabeum和Pleurotus ostreatus在未经碾磨的甘蔗渣上生长长达四个月。微生物生长后，使用3％和6％（m / v）的过氧化氢对木聚糖进行化学溶解。生物预处理后，使用3％的过氧化氢可在第四个月后将木聚糖增溶为C. puteana，并在第一个月后将48.63％的木聚糖溶解为小梁茶。生长。结果表明，生物预处理通过改变甘蔗渣的结构降低了甘蔗渣的拒食性，从而可以溶解更多数量的木聚糖，并使用一半的化学试剂，从而提高了工艺的可行性。
