【表】DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for detecting microorganisms harmful to brewing, and more particularly to a method for detecting microorganisms harmful to brewing that may appear during the brewing of beer or the like. Currently, Lysine medium and Crystal-Violet medium are widely used to detect wild yeasts that appear during the beer brewing process, but these methods involve culturing and therefore lack speed. Furthermore, as an alternative method, it has been proposed to detect harmful microorganisms by a serological method such as a fluorescent antibody method. Although this method is superior to the above-mentioned methods in terms of speed, it is less convenient because it requires the use of several types of antisera and the combined results of each. For example, the method previously developed by the present inventors uses factor antibodies for identifying pathogenic Candeida spp., which are currently commercially available in Japan, but it requires the use of five types of factor antibodies, making the operation complicated. Therefore, it cannot be said to be an effective method. The present invention overcomes the above-mentioned drawbacks and provides a method for quickly and conveniently detecting microorganisms harmful to brewing by using a single factor antibody. The present invention involves preparing a factor antibody by absorbing an antiserum obtained using yeast belonging to the genus Candeida or Satucharomyces with brewer's yeast, and bringing the factor antibody into contact with a test yeast. Determining the properties of the yeast based on whether or not it occurs,
This detects microorganisms that are harmful to brewing. The present inventors have conducted extensive research to develop a method for quickly and accurately detecting harmful microorganisms generated during the brewing process using a single factor antibody. It has been found that a factor antibody prepared by absorbing the antiserum using brewer's yeast as an absorption bacterium is suitable for the purpose of the present invention. The antiserum used is Candida guilliermondi (ATCC-
9058), Saccharomyces cerevisiae J-6001, S.pastrorianus,
BSRI-1-12), Satucharomyces rosei (S.
rosei, ATCC-0428), S.bisporus (ATCC-0723) and S.uvarum (BSRI-1-)
9) are obtained by immunizing rabbits using yeast as an antigen. A factor antibody is prepared by immunizing a rabbit with the above bacterial strain as an antigen and absorbing the antiserum obtained with brewer's yeast. Brewing yeast may be selected depending on the purpose of use; for example, yeast for beer brewing includes bottom beer yeast and top beer yeast, and other types include sake yeast, wine yeast, whiskey yeast, alcohol yeast, and the like. A single factor antibody may be used, or two or more may be used in combination. In particular, a combination of a factor antibody using Satucharomyces pastorianus as an antigen and a factor antibody using Satucharomyces bisporus as an antigen, a factor antibody using Satucharomyces cerevisiae as an antigen, and a factor antibody using Candeida guilliamondei as an antigen. A combination of these can detect harmful microorganisms at a very high rate. When the factor antibody according to the present invention is brought into contact with a test yeast, an agglutination reaction occurs except when the test yeast is a brewing yeast used as an absorption bacterium. Such behavior of the test yeast is due to differences in the antigenic structure of the yeast, and according to the present invention, microorganisms harmful to brewing can be quickly and accurately detected using only a single factor antibody. I can do it. Contact between the factor antibody and the test yeast can be carried out on a slide glass, making it possible to confirm the presence or absence of an agglutination reaction in a short time. Furthermore, if necessary, a large number of test yeasts can be tested at the same time. The factor antibodies used in the method of the present invention can also be effectively used in known fluorescent antibody methods and culture methods. Next, examples of the present invention will be shown. Example 1 S.bisporus (S.bisporus,
Antiserum was obtained using S. carlsbergensis (ATCC-0723) as an antigen, and the antiserum was used as an antigen for S.
4778) and prepared the factor antibody by a conventional method. Next, when slide agglutination reaction was attempted on 16 wild yeast strains using this factor antibody, the detection rate was 75%. Example 2 S. uvarum (BSRI-1-9) instead of S. bisporus
Slide agglutination reaction was attempted using the same method as in Example 1, except that the detection rate was 45%.
It was hot. Example 3 C. guilliermondii (C. guilliermondii,
When a slide agglutination reaction was attempted in the same manner as in Example 1 except that ATCC-9058) was used, the detection rate was 69%. Example 4 As factor antibodies, S. pastorianus (BSRI-1-12) and S. bisporus (ATCC
-0723) respectively as antigens.
A combination of species factor antibodies was used, and the rest was as in Example 1.
When I tried the same operation as , the detection rate of wild yeast was
It was 94%. Example 5 S. cerevisiae (J-6001) and C. guilliermondii (ATCC) were used as factor antibodies.
-9058) were prepared using each as an antigen.
A combination of species factor antibodies was used, and the rest was as in Example 1.
When I tried the same operation as above, the detection rate of wild yeast was
It was 88%. Example 6 As factor antibodies, S. cerevisiae (J-6001), S. bisporus (S. bisporus, ATCC-0723), and S. uvarum (BSRI-1)
-9) respectively as antigens, and using a combination of three types of factor antibodies prepared, and performing the same procedure as in Example 1, the wild yeast detection rate was 63.
It was %. Example 7 Wild yeast 72
When testing 63 strains of bottom brewer's yeast, the detection rate was 91% for wild yeast and 83% for B.
For bottom brewer's yeast, both A and B
It was 100%. When 32 strains of wild yeast belonging to the genus Satucharomyces were similarly tested, the detection rate was 100% for A and 86% for B. Reference Example 1 A sample obtained by adding 100 cells each of S. ellipsoideus and S. ellipsoideus to sterilized beer 1 was filtered through a membrane, and then the combination of the two factor antibodies used in Example 4 was obtained. Determine the number of fluorescent cells by fluorescent antibody method using
When the number of cells was determined by a culture method using a wort medium, the following results were obtained, and both measurement methods were in agreement. 【table】
