微生物在白酒酿造中具有十分重要的地位,它们所分泌的多种酶类物质能够酶解酿酒原料中的淀粉、蛋白质、纤维素等物质,其生长所形成的代谢产物又往往决定了白酒的香型和品质,所以微生物可以被称之为是白酒酿造的灵魂。该文从酵母菌、丝状真菌、乳酸菌、芽孢杆菌、放线菌这5个方面对牛栏山白酒酿造过程中微生物的种类及变化规律进行详细介绍,确定了牛栏山二锅头酒发酵过程中的主要微生物,同时概述了不同微生物的变化规律及其在发酵过程中的作用,旨在为牛栏山二锅头酒的酿造过程及机理研究提供理论支撑。 相似文献

酱香型白酒中的酸基本为有机酸,且"酸高"是酱香型白酒的一大特点。主要探索了有机酸在酱香型白酒酿造过程中对微生物的调控作用。结果表明:①在除酸度外的相同条件下培养,不同的酸度对微生物的生长影响不同;②在不同的培养基上,随酸度的变化其微生物的变化趋势具有一致性。有机酸是酱香型白酒酿造过程中一个非常重要的因素,在一定程度上调控着酱香型白酒的酿造过程。 相似文献

Lactic acid bacteria and their metabolites play important roles in defining Chinese liquor flavour. Currently, the role of lactic acid bacteria in liquor brewing remains unclear. This review discusses the role of lactic acid bacteria in fermentation of different types of Daqu and fermented grains. It focuses on the interaction between these bacteria and other microorganisms during liquor brewing, and analyses its effect on liquor flavour and quality. In addition, the roles of Lactobacillus in reducing the amount of unfavourable ingredients in liquor and the succession law of lactic acid bacteria during the fermentation of three Daqu liquors were also studied. Finally, the methods aimed at reducing lactic acid production and improving liquor quality are discussed. Overall, the review highlights the significance of lactic acid bacteria for brewing Daqu liquor. Nevertheless, further studies are required to clarify the role and mechanism of action of lactic acid bacteria during liquor fermentation. © 2019 The Institute of Brewing & Distilling 相似文献

酒曲是中国白酒酿造必不可少的糖化、发酵和生香剂。根据制曲工艺不同,将酒曲分为大曲、小曲、红曲、麦曲、麸曲、高温曲、中温曲、低温曲等类别。我国主要名优白酒是以大曲为起酵剂。大曲中微生物菌系非常复杂,种类繁多。生香动力的细菌、糖化主力的霉菌以及酒醅发酵原动力的酵母等微生物,不断交替更迭的作用,共同维持着白酒发酵的正常进行。传统固态酿造过程中,大曲中微生物在大曲酒的品质、风味呈现方面扮演着极为重要的角色。该文依据大曲原料和制作工艺,简要介绍了大曲中微生物的来源、主要微生物类群以及各类微生物的主要功能,并在此基础上对大曲微生物和白酒酿造研究方面提出展望。 相似文献

As one of the three major distilled spirits in the world, traditional Chinese liquor has a distinctive aroma and taste. The brewing process typically involves two stages: the Daqu‐making process and the liquor‐making process. Further, it commonly adopts solid state fermentation in an open environment, which involves diverse microorganisms such as bacteria and fungi. Yeasts, as an integral brewing microorganism, are not only a dominant force in the fermentation process but also play a key role in the quality and character of different flavour liquors. Studies on yeasts associated with Chinese liquor have rarely compared them with those associated with other alcoholic beverages (wine, sake, etc.), especially in the microbiome‐related flavour of the alcoholic beverage. Here, we review the Chinese liquor brewing process, the yeast community in the brewing process, the yeast derived flavour compounds, the interaction between yeasts and other microorganisms and gene level modifications. © 2019 The Institute of Brewing & Distilling 相似文献

利用大曲作为糖化发酵剂是中国传统白酒主要的工艺特点之一。大曲中的微生物组成十分丰富包括各种种类的霉菌、酵母以及细菌,这些复杂的微生物体系为白酒的发酵提供了必要的微生物、酶以及风味物质。其中霉菌作为酒类发酵生产中必不可少的微生物,在大曲发酵过程中能够分泌一些糖化酶和蛋白酶等多种酶类以及有机酸等多种代谢产物,对大曲质量好坏起着重要作用。为了探究大曲中霉菌功能,本文对不同时期大曲中分离的霉菌采用ITS4/5 rRNA区序列进行分析比对,共分离鉴定了193株霉菌,分属于13个种。主要为红曲(Aspergillus ruber),米根霉(Rhizopus oryzae),微小根毛霉(Rhizomucor pusillus),Rhizopus azygosporus,烟曲霉(Aspergillus fumigatus),嗜热子囊菌(Thermomyces lanuginosus),谢瓦氏曲霉(Aspergillus salwaensis),Aspergillus chevalieri,米曲霉(Aspergillus oryzae)等,并构建了M-L系统树。根据这些分离鉴定的结果初步探究出大曲生产过程中不同时期霉菌的组成和变化规律。这些结果为进一步研究中国传统白酒的酿造微生物奠定了一定的基础。 相似文献

从制浆黑液贮存塘的底泥中分离出厌氧微生物,将其用来处理浓度10%的制浆黑液,研究表明,黑液与菌液体积比为2∶1是厌氧降解反应的最佳反应条件之一。同时测定了厌氧生物降解过程中黑液pH值、总糖含量、糖醛酸含量、化学需氧量(COD)、酸溶木质素含量、酸不溶木质素(Klason木质素)含量随时间变化的趋势,初步研究了制浆黑液厌氧降解的过程。研究结果表明,在厌氧生物降解过程中pH值、总糖含量、糖醛酸含量、COD、酸不溶木质素含量在黑液中都呈下降趋势,而酸溶木质素含量在该过程中不断上升。 相似文献
