Utilized and waste jasmine flower contains a high portion of organic carbohydrate and other organic acids, making it a suitable substrate for bioethanol production. This study was designed to estimate the prospective of waste jasmine flower biomass applied with chemical (alkaline) and thermal pretreatment applied on samples through bioethanol production efficiencies. Therefore, pretreatment and enzymatic hydrolysis are directed to disrupt the complex cell wall layer and improve the accessibility towards polysaccharide fraction. Also, applying response surface methodology tools during fermentative bioethanol production to study the interactive effects of different bioprocess variables for higher bioethanol yield in batch small and large scale model is discussed. The immobilized yeast between jasmine found that jasmine sugar utilization was 50%. The jasmine flower's ethanol production was 6.54 g/L and after distillation of jasmine was 31.40 g/L at pH 4.5. Results showed that this immobilized yeast method could be successfully used for bioethanol production from waste jasmine flower.
利用后的废弃茉莉花含有高比例的有机碳水化合物和其他有机酸，使其成为生物乙醇生产的合适底物。本研究旨在通过生物乙醇生产效率来评估经化学（碱性）和热预处理的废弃茉莉花生物质的前景。因此，预处理和酶水解旨在破坏复杂的细胞壁层并提高对多糖部分的可及性。此外，还讨论了在发酵生物乙醇生产过程中应用响应面方法工具，以研究不同生物过程变量在分批小规模和大规模模型中对更高生物乙醇产量的交互作用。固定在茉莉花中的酵母发现茉莉花糖利用率为50%。在pH值为4.5时，茉莉花的乙醇产量为6.54 g/L，蒸馏后的茉莉花乙醇产量为31.40 g/L。结果表明，这种固定化酵母方法可成功用于从废弃茉莉花中生产生物乙醇。
