新型酵母菌株可比传统菌株多产生约15.5%的乙醇#标题分割#人工智能朗读:印度研究人员近日分离出一种新型酵母菌株,利用这种菌株发酵农作物秸秆等木质纤维素,可比传统菌株发酵多产生约15.5%的乙醇。新华网2019年4月18日讯印度研究人员近日分离出一种新型酵母菌株,利用这种菌株发酵农作物秸秆等木质纤维素,可比传统菌株发酵多产生约15.5%的乙醇。据介绍,利用传统酵母菌株发酵水稻和小麦秸秆等木质纤维素生产乙醇,主要有以下瓶颈:需要将环境温度控制在30摄氏度以内,以确保发酵效果;酵母只对纤维素中部分成分有效,对其中的树胶醛醣等无效,不能充分利用;木质纤维素在预处理时会产生糠醛等抑制剂,降低发酵性能。印度的国际遗传工程和生物技术中心研究人员纳西姆·高尔等人在新一期英国《生物燃料技术》杂志上发表报告说,他们从酿酒厂废料、乳制品废料、温泉等多种样本来源中分离出500个类似酵母的菌落,再将从中分离出的菌株与已有酵母菌株进行比较,发现一种代号为NGY10的菌株最适合用于水稻和小麦秸秆发酵。与目前市场上的酵母菌株相比,最新分离出的这种菌株具有耐热性,在40摄氏度环境下也能继续发酵,发酵性能不受糠醛等抑制剂影响,并能发酵纤维素中几乎全部有效成分,从而提高产量、降低成本。新型酵母菌株可比传统菌株多产生约15.5%的乙醇#标题分割#人工智能朗读:印度研究人员近日分离出一种新型酵母菌株,利用这种菌株发酵农作物秸秆等木质纤维素,可比传统菌株发酵多产生约15.5%的乙醇。新华网2019年4月18日讯印度研究人员近日分离出一种新型酵母菌株,利用这种菌株发酵农作物秸秆等木质纤维素,可比传统菌株发酵多产生约15.5%的乙醇。据介绍,利用传统酵母菌株发酵水稻和小麦秸秆等木质纤维素生产乙醇,主要有以下瓶颈:需要将环境温度控制在30摄氏度以内,以确保发酵效果;酵母只对纤维素中部分成分有效,对其中的树胶醛醣等无效,不能充分利用;木质纤维素在预处理时会产生糠醛等抑制剂,降低发酵性能。印度的国际遗传工程和生物技术中心研究人员纳西姆·高尔等人在新一期英国《生物燃料技术》杂志上发表报告说,他们从酿酒厂废料、乳制品废料、温泉等多种样本来源中分离出500个类似酵母的菌落,再将从中分离出的菌株与已有酵母菌株进行比较,发现一种代号为NGY10的菌株最适合用于水稻和小麦秸秆发酵。与目前市场上的酵母菌株相比,最新分离出的这种菌株具有耐热性,在40摄氏度环境下也能继续发酵,发酵性能不受糠醛等抑制剂影响,并能发酵纤维素中几乎全部有效成分,从而提高产量、降低成本。
