酱香型高温大曲中功能菌B_(3-1)菌株的分离、选育及其分类学鉴定

Separation,Breeding Selection and Taxonomic Determination of Functional Bacteria Strain B_(3-1) from High Temperature Daqu Starter for Maotai-flavor Liquors

以酱香型白酒生产所使用的高温大曲为含菌样品,经分离获多株耐高温细菌,对它们进行生化及香气特征测定,确认B3-1菌株为主要功能菌。经形态特征、生理生化特征的测定,B3-1菌株归属于地衣芽孢杆菌。

High temperature Daqu sta rt er,applied in the production of Maotai-flavor liquors,was used as samples.An d multiple strains of high temperature resistant bacteria were obtained through separation of the samples.Then the biochemical properties and the flavor chara cteristics of the strains were determined and the strain B 3-1 was affirmed the main functional bacteria and it belongs to Bacillus licheni formis Chester by the determination of its conformation and biochemical properti es.(Tran.by YUE Yang)
