The use of fruit residues from domestic consumption for energy purposes is a perspective of innovation in the search for a more sustainable fuel, due to the low cost of this biomass, combined with its large amounts of generation, which has sugars readily available in its composition and does not require process pretreatment hydrolysis complexes of the material. This work evaluated residues of melon, pineapple, banana, apple, and mango, to compose a mixture of fruit waste (MFW), simulating a household waste for bioethanol production by a non-conventional yeast Wickerhamomyces sp. UFFS-CE-3.1.2. Sugar extraction was optimized by experimental design (MFW: 12% g dry mass v⁻¹; 25 °C; 5 min) and resulted in the liberation of 36.32 ± 0.72 g L⁻¹ fermentable sugar. MFW was used for alcoholic fermentation with and without nitrogen supplementation (urea and yeast extract). The results demonstrated that it is not necessary for the supplementation, making the process more economically viable. The maximum ethanol productivity (2.50±0.06 g L⁻¹ h⁻¹) was achieved in 9 h of the operation. The MFW extracted is an alternative for the bioethanol process as low cost and straightforward, adapted for different fruit residues, and used as a unique or diluent medium in the biorefinery context. Moreover, non-conventional yeast demonstrated the more new one in this study that explores the potential of yeast recently isolated.

由于这种生物质的成本低廉，再加上其大量的产生，其构成中容易获得糖分，因此将家庭消费中的水果残渣用于能源目的是一种创新的观点，即寻求一种更具可持续性的燃料并且不需要工艺预处理的材料水解络合物。这项工作评估了瓜，菠萝，香蕉，苹果和芒果的残留物，以构成水果废料（MFW）的混合物，模拟了由非常规酵母Wickerhamomyces sp生产的生物乙醇的家庭废料。UFFS-CE-3.1.2。通过实验设计（MFW：12％g干质量v ^-1； 25°C； 5分钟）优化糖提取，并释放出36.32±0.72 g L ^-1可发酵的糖。MFW用于酒精发酵，添加和不添加氮（尿素和酵母提取物）。结果表明，不需要补充，使该方法在经济上更可行。在操作的9小时内达到最大乙醇生产率（2.50±0.06 g L ^-1 h ^-1）。提取的MFW是低成本，简单易行的生物乙醇工艺的替代产品，适用于不同的水果残留物，并在生物精炼厂中用作独特或稀释的介质。而且，非常规酵母在这项研究中展示了更多新的酵母，该酵母探索了最近分离出的酵母的潜力。
