Description

この発明は、腐敗臭などの消臭に用いられる消臭液、その調製方法およびその調製キットに関する。   The present invention relates to a deodorant liquid used for deodorization such as rot odor, a preparation method thereof, and a preparation kit thereof.

従来、ゴミや屎尿などの臭いを消臭する方法として、オゾンによる酸化などの化学反応により臭い分子を無臭の成分に変える方法や、活性炭を用いて臭い分子を吸着させる方法が、周知である。さらにはまた、悪臭の元となる臭い分子をシクロデキストリン等の分子と複合化させることによって消臭する方法も、周知である。   Conventionally, as a method for deodorizing odors such as dust and manure, a method of changing odor molecules into odorless components by a chemical reaction such as oxidation by ozone, and a method of adsorbing odor molecules using activated carbon are well known. Furthermore, a method of deodorizing by combining a odor molecule that causes bad odor with a molecule such as cyclodextrin is also well known.

オゾンのような酸化剤などを使用する場合、金属製品に対して用いると、さびによる金属製品の劣化を招く恐れがある。また、腐敗臭などの有機性の悪臭を分解する成分は、人体に有害である場合が多い。活性炭は、高価であるにもかかわらず、交換を頻繁にしなければならないという問題がある。シクロデキストリンなどにより臭い分子を取り込む方法もまた、コストの高いものになりがちな上に、効果が持続しにくいという難点がある。
このような観点からすると、人体に対して安全であり、金属等を劣化させず、安価で持続性の高い消臭剤が、必要とされているということができよう。
When an oxidizing agent such as ozone is used, it may cause deterioration of the metal product due to rust when used on a metal product. In addition, components that decompose organic malodors such as spoiled odor are often harmful to the human body. Although activated carbon is expensive, there is a problem that it must be replaced frequently. Incorporating odorous molecules with cyclodextrin and the like also tends to be costly and has a drawback that the effect is difficult to sustain.
From this point of view, it can be said that there is a need for a deodorant that is safe for the human body, does not deteriorate metals, and is inexpensive and highly durable.

この発明に係る消臭液は、7.6×10個/ml以上であって1.9×10個/ml以下の菌体濃度である枯草菌を含む。菌類が増殖する際、増殖前の菌体数が大きいほど増殖後の菌体数も大きくなるのが一般的であるが、枯草菌は、増殖が始まる際に密集状態にある場合には増殖しないという性質があるため、この発明において、枯草菌の増殖に最適な濃度を決定した。本明細書中で、枯草菌の菌体数を示す数字は全て、有効数字2桁で記されている。ここで、枯草菌は、好ましくは、バチルス・アシドカルダリウス(Bacillus acidocaldarius)、バチルス・アルベイ(Bacillus alvei)、バチルス・アミロリケファシエンス(Bacillus amyloliquefaciens)、バチルス・ブレビス(Bacillus brevis)、バチルス・フィルコロニカス(Bacillus filicolonicus)、バチルス・メガテリウム(Bacillus megaterium)、バチルス・プミルス(Bacillus pumilus)、バチルス・スパリカス(Bacillus sphaericus)、バチルス・サブティリス(Bacillus subtilis)およびバチルス・サブティリス亜種サブティリス(Bacillus subtilis subsp subtilis)から成る群より選択される。枯草菌は、上記の群のうち1種を含むものであっても、2種以上を含むものであってもよい。好ましくは、枯草菌は、上記の群のうち1〜5種を含み、最も好ましくは、5種を含む。 The deodorizing liquid according to the present invention includes Bacillus subtilis having a cell concentration of 7.6 × 10 5 cells / ml or more and 1.9 × 10 5 cells / ml or less. When fungi grow, the larger the number of cells before growth, the larger the number of cells after growth, but Bacillus subtilis does not grow if it is in a dense state at the start of growth. In this invention, the optimum concentration for the growth of Bacillus subtilis was determined. In the present specification, all numbers indicating the number of cells of Bacillus subtilis are written in two significant digits. Here, Bacillus subtilis is preferably Bacillus acidocaldarius, Bacillus albei, Bacillus amyloliquefaciens, Bacillis biscil, Colonicus (Bacillus ficilonicus), Bacillus megaterium, Bacillus pumilus, Bacillus sphaericus, Bacillus subtilis (Bacillus subtilis) It is selected from the group consisting of illus subtilis subsp subtilis).

非活性状態にある枯草菌の活性化条件は、40℃〜60℃で20分間〜60分間の加熱であり、好ましくは、45℃〜50℃での加熱である。
上記条件で非活性状態の枯草菌を加熱することにより、枯草菌が芽胞から発芽し、栄養条件下で増殖可能な活性状態となる。ここで、栄養条件下とは、ソイビーンカゼインダイジェスト培地等の培養培地、あるいは生ゴミまたは屎尿等の、枯草菌が栄養を吸収し得る物質の存在下にあることを意味する。

48時間後に対照サンプルを加えたフラスコBから発せられた主な臭気は、スカトールであり、96時間後に対照サンプルを加えたフラスコBから発せられた主な臭気は、アンモニアであった。
以上より、枯草菌液Aの4.0×10倍希釈液(1.9×10個/mlの菌体濃度で枯草菌を含む)には、消臭効果があることが分かった。
The main odor emanating from Flask B with the control sample added after 48 hours was skatole, and the main odor emanating from Flask B with the control sample added after 96 hours was ammonia.
From the above, it was found that a 4.0 × 10 3 dilution of Bacillus subtilis solution A (containing Bacillus subtilis at a cell concentration of 1.9 × 10 5 cells / ml) has a deodorizing effect.
