Vinasse is a by-product of the sugar and alcohol industry with high toxicity and crop fertilization capacity. The bioconversion of vinasse to high-value products could represent an opportunity to reduce operating costs and environmental footprints. In this study, exopolysaccharides (EPSs) and fungal biomass were produced by different species of the genus Pleurotus (Pleurotus sajor-caju CCB 020, Pleurotus florida, Pleurotus ostreatoroseus, Pleurotus flabellatus, Pleurotus sp. CCB 068, and Pleurotus spleurotus) in submerged culture supplemented with different vinasse medium formulations. The highest yield of EPSs (about 7 g/L) was observed in the P. florida strain and the highest biomass in Pleurotus sp. CCB 068 with 28.8 g/L, after 14 days of fermentation. Results revealed that 100% vinasse is a suitable medium to achieve increased protein-rich biomass, exopolysaccharide content and minerals accumulation in the fungal biomass. Sugars predominant in the exopolysaccharide matrix were glucose, galactose, and mannose. Furthermore, the treatment of vinasse with Pleurotus provided efficient removal of color (98.8%) and turbidity (99%). The biomass following vinasse treatment can then be utilized for animal feed and human food supplementation, thus adding economic value to vinasse production.

用于提高平菇生物质生产力的酒糟生物价值化：化学表征和碳水化合物分析

酒糟是制糖和酒精工业的副产品，具有高毒性和作物施肥能力。将酒糟生物转化为高价值产品可能是降低运营成本和环境足迹的机会。在这项研究中，外多糖 (EPSs) 和真菌生物量由不同物种的平菇属( Pleurotus sajor-caju CCB 020、Pleurotus florida、Pleurotus ostreatoroseus、Pleurotus flabellatus、Pleurotus sp. CCB 068 和Pleurotus inpleurotus inpleurotus ) 产生辅以不同的酒糟培养基配方。EPSs 的最高产量（约 7 g/L）在P. florida菌株和Pleurotus sp. 中最高的生物量。CCB 068 28.8 g/L，发酵 14 天后。结果表明，100% 酒糟是一种合适的培养基，可增加真菌生物质中富含蛋白质的生物质、胞外多糖含量和矿物质积累。胞外多糖基质中的主要糖是葡萄糖、半乳糖和甘露糖。此外，用平菇处理酒糟可有效去除颜色 (98.8%) 和浊度 (99%)。酒糟处理后的生物质可用于动物饲料和人类食品补充，从而为酒糟生产增加经济价值。
