The aim of this study was to develop integrated biofuel (cellulosic bioethanol) and biochemical (succinic acid) production from industrial hemp (Cannabis sativa L.) in a biorefinery concept. Two types of pretreatments were studied (dilute-acid and alkaline oxidative method). High cellulose recovery (>95%) as well as significant hemicelluloses solubilization (49-59%) after acid-based method and lignin solubilization (35-41%) after alkaline H2O2 method were registered. Alkaline pretreatment showed to be superior over the acid-based method with respect to the rate of enzymatic hydrolysis and ethanol productivity. With respect to succinic acid production, the highest productivity was obtained after liquid fraction fermentation originated from steam treatment with 1.5% of acid. The mass balance calculations clearly showed that 149kg of EtOH and 115kg of succinic acid can be obtained per 1ton of dry hemp. Results obtained in this study clearly document the potential of industrial hemp for a biorefinery.
本研究旨在开发从工业大麻（Cannabis sativa L.）中以生物炼制概念生产综合生物燃料（纤维素生物乙醇）和生物化学物质（琥珀酸）。研究了两种预处理方法（稀酸和碱性氧化法）。酸基方法后纤维素回收率高（>95%），半纤维素显著溶解（49-59%），碱性 H2O2 方法后木质素溶解（35-41%）。就酶水解和乙醇生产力而言，碱性预处理优于基于酸的方法。就琥珀酸生产而言，源自蒸汽处理的液体部分发酵，酸浓度为 1.5%时，可获得最高的生产力。质量平衡计算清楚地表明，每 1 吨干大麻可获得 149 千克乙醇和 115 千克琥珀酸。本研究的结果清楚地证明了工业大麻在生物炼制中的潜力。
