Making use of the jiyairesu gene, decides the beer turbidity Characteristic of the Lactobacillus brevis germ the mannered

摘要

PROBLEM TO BE SOLVED: To provide a method for rapidly and accurately discriminating whether or not a test bacterium belonging to a Lactobacillus brevis strain is a strain having proliferation potency, i.e., beer turbidity.;SOLUTION: The discrimination of the beer turbidity is carried out based on a cleavage pattern by a restriction enzyme, obtained by amplifying a part of a B-gene region of the test Lactobacillus brevis strain by using as DNA gyrase subunit B gene (gyrB)-specific primer, and cleaving the amplified DNA fragment by the restriction enzyme.;COPYRIGHT: (C)2003,JPO
