Paecilomyces variotii, composition and application thereof

The invention discloses paecilomyces variotii for brewing white spirit, a fungicide and application of a composition of paecilomyces variotii and the fungicide in fermenting the white spirit. The paecilomyces variotii provided by the invention has the capability of producing high-yield saccharifying enzyme and high-yield alpha-amylase activity, is high in content of white spirit flavor substances such as tetramethylpyrazine and 2-methyl ethyl butyrate, and also has the characteristics of strong high-temperature resistance and the like. The strain can be used for fermentation production of Baijiu, the Baijiu yield and the content of total acid, total ester, tetramethylpyrazine and the like of the Baijiu are improved, and the taste and flavor of the Baijiu are improved. 本发明公开了一种用于白酒酿造的宛氏拟青霉菌，菌剂及其组合物在发酵白酒中的应用。本发明提供的宛氏拟青霉菌具有高产糖化酶和高产α-淀粉酶活力的能力，产四甲基吡嗪和2-甲基丁酸乙酯等白酒风味物质含量高，同时又具有耐高温能力强等特性。该菌株可用于发酵生产白酒，提高白酒出酒率、总酸、总酯和四甲基吡嗪等含量，提高白酒的口感和风味。
