さらに2時間放置した後、室内の濾紙を回収した。この濾紙を寒天培地上に載せ、供試菌の胞子懸濁液を接種した。これを27℃で10日間放置した後、濾紙上に繁殖した各供試菌の生育状況を観察した。
結果を表1に示す。
Next, test examples of the antibacterial activity of the antibacterial agent of the present invention will be described.
Test example 1
0.5 g of 4-hydroxy-6-methyl-3- (4-methylpentanoyl) -2-pyrone and 0.1 g of 2,6-di-tert-butyl-4-methylphenol were sufficiently mixed with stirring. . This was placed in the upper part of the container 4 shown in FIG. 1, 60 g of 1-20 mesh calcium oxide was placed in the lower part of the container 4, and the bottom of the container was covered with a water-permeable nonwoven fabric.
On the other hand, a total of 12 filter papers each having a diameter of 7 cm were installed on the bottom surface of four corners, a wall surface of a height of 90 cm, and a ceiling in a room of 5.8 m 3 (1.8 mx 1.8 mx 1.8 m). In addition, a wool fabric with a smell of tobacco (20 cm × 20 cm square) was placed on the indoor floor, and the smell of tobacco was further drifted indoors.
A container 2 containing 25 ml of water was placed at the center of the floor in this room. The container 4 was placed therein, and the container 4 was heated by the reaction between water and calcium oxide. After leaving it for 20 minutes, it ventilated for 10 minutes with the ventilation fan installed in the test room. At this time, the wool cloth placed indoors and indoors did not feel the smell of tobacco.
After further standing for 2 hours, the filter paper in the room was collected. The filter paper was placed on an agar medium, and a spore suspension of the test bacterium was inoculated. After leaving this at 27 ° C. for 10 days, the growth status of each test bacterium propagated on the filter paper was observed.
Table 1 shows the results.

試験例2
2,6−ジ−tert−ブチル−4−メチルフェノール0.1gの代わりに3,9−ビス[1,1−ジメチル−2−{β−(3−tert−ブチル−4−ヒドロキシ−5−メチルフェニル)プロピオニルオキシ}エチル]2,4,8,10−テトラオキサスピロ[5.5]ウンデカン0.1gを用いた以外は、試験例1と同様にして試験を行った。
結果を表2に示す。
Test example 2
Instead of 0.1 g of 2,6-di-tert-butyl-4-methylphenol, 3,9-bis [1,1-dimethyl-2- {β- (3-tert-butyl-4-hydroxy-5) is used. The test was conducted in the same manner as in Test Example 1 except that 0.1 g of [methylphenyl) propionyloxydiethyl] 2,4,8,10-tetraoxaspiro [5.5] undecane was used.
Table 2 shows the results.

The symbols and abbreviations in the table have the same meaning as in Table 1.

また、薬剤を処理してから20分間放置した後、試験室に設置された10分間換気した時点で室内及び室内に置いたウール布は、タバコ臭が感じられなかった。   Further, after the medicine was treated and left for 20 minutes, the room and the wool cloth placed in the room at the time of ventilation for 10 minutes provided in the test room did not feel smell of tobacco.

比較例
2,6−ジ−tert−ブチル−4−メチルフェノールを用いず、4−ヒドロキシ−6−メチル−3−(4−メチルペンタノイル)−2−ピロン0.5gのみを有効成分とした以外は実施例1と同様にして試験を行った。
結果を表3に示す。
Comparative Example Only 0.5 g of 4-hydroxy-6-methyl-3- (4-methylpentanoyl) -2-pyrone was used as an active ingredient without using 2,6-di-tert-butyl-4-methylphenol. A test was performed in the same manner as in Example 1 except for the above.
