本発明のホルムアルデヒド分解剤に含ませる微生物菌は、バチルススパリカス（Bacillus sphaericus）微生物菌、バチルスサブチルス（Bacillus subtilis）微生物菌、またはバチルスツリュゲナイセス（Bacillus thuringiensis）微生物菌であり、これらの微生物菌は公知の物であり、土壌、海水、淡水性堆積物中、食物などから容易に培養することができる。しかもこれらの微生物菌は、環境や人体に安全なものであり、これらを使用するホルムアルデヒド分解剤も、極めて安全性の高い製品として提供することが可能となる。   The microbial bacteria to be included in the formaldehyde decomposition agent of the present invention are Bacillus sphaericus microbial bacteria, Bacillus subtilis microbial bacteria, or Bacillus thuringiensis microbial bacteria. These microorganisms are known and can be easily cultured from soil, seawater, freshwater sediments, foods, and the like. Moreover, these microorganisms are safe for the environment and the human body, and it is possible to provide formaldehyde decomposing agents using them as extremely safe products.

本発明に用いる家畜糞は、牛糞、豚糞、又は鶏糞が好ましく、その他、馬糞をはじめ多様な家畜の糞も必要に応じて用いることが可能である。家畜糞の中には雑菌が多く含まれており、これらの菌の影響を除去するため、６０度〜１５０度で５時間に渡り高温処理を行う。高温処理された家畜糞は乾燥し、固形状となっており、固形状の家畜糞を粉砕し、粉体化したものに本発明の微生物菌を混合する。   The livestock droppings used in the present invention are preferably cow droppings, pig droppings, or chicken droppings, and various animal droppings such as horse droppings can be used as necessary. Livestock excrement contains many germs, and in order to remove the effects of these germs, high temperature treatment is performed at 60 to 150 degrees for 5 hours. The livestock excrement treated at high temperature is dried and solid, and the microbe of the present invention is mixed with the solid livestock excrement pulverized and powdered.

本発明によれば、上記微生物菌に高温処理した家畜糞を混合することで得られる粉体は、それ自体でもホルムアルデヒドを分解する作用を有するものであるが、より好ましくは、該粉体に水分を加える事により、ホルムアルデヒド分解効果をより高めることが可能となる。   According to the present invention, the powder obtained by mixing the above-mentioned microbial fungus with the livestock excrement treated with high temperature itself has an action of decomposing formaldehyde, but more preferably, the powder has moisture. By adding, it becomes possible to further enhance the formaldehyde decomposition effect.

また、本発明によれば、上記粉体を液体にし、さらに吸水ゲル化剤並びにゼラチン、寒天に入れることで、ゲル状態のホルムアルデヒド分解剤を得ることができる。
このように、本発明のホルムアルデヒド分解剤は、粉体、液体、又はゲル状態など多様な形態を選択することが可能であるため、極めて利用範囲の広いホルムアルデヒド分解剤を提供することが可能となる。 Further, according to the present invention, the formaldehyde decomposition agent in a gel state can be obtained by making the powder into a liquid and further putting it in a water-absorbing gelling agent, gelatin and agar.
Thus, since the formaldehyde decomposing agent of the present invention can be selected from various forms such as powder, liquid, or gel state, it is possible to provide a formaldehyde decomposing agent having a very wide range of use. .

次に、本発明のホルムアルデヒド分解剤の使用方法について説明する。
粉体状、液体状、さらにはゲル状のいずれにおいても、容器内にホルムアルデヒド分解剤を収容し、ホルムアルデヒドが存在する室内やホルムアルデヒドの発生源の傍に設置することにより、容易にホルムアルデヒド分解剤を使用することが可能である。 Next, a method for using the formaldehyde decomposing agent of the present invention will be described.
Whether in powder, liquid, or gel form, the formaldehyde decomposer is contained in a container and placed in a room where formaldehyde is present or near the source of formaldehyde. It is possible to use.

さらには、液状のホルムアルデヒド分解剤については、ホルムアルデヒドの発生源となる壁紙や壁の仕上げ剤表面、家具や建具などの表面に、本発明のホルムアルデヒド分解剤を吹付けて使用することも可能である。また、液体を吸収可能なものには、吹付けや塗布などにより対象物の表面から内部にホルムアルデヒド分解剤を吸収させることも可能である。また、ホルムアルデヒドを含む気体中やホルムアルデヒドと接触する物体の表面に、ホルムアルデヒド分解剤を吹き付けることも可能である。   Furthermore, the liquid formaldehyde decomposing agent can be used by spraying the formaldehyde decomposing agent of the present invention on the surface of wallpaper, wall finish, furniture, fittings, etc., which is the source of formaldehyde. . For those that can absorb liquid, the formaldehyde decomposition agent can be absorbed from the surface of the object into the interior by spraying or coating. It is also possible to spray a formaldehyde decomposing agent in a gas containing formaldehyde or on the surface of an object in contact with formaldehyde.

ホルムアルデヒドは、水溶性であるため、水中内のホルムアルデヒドを分解する際には、粉体状又は液体状のホルムアルデヒド分解剤を、水中に散布するか、ホルムアルデヒド分解剤を含む固形のブロックを形成し、水中内に配置する方法なども可能である。   Since formaldehyde is water-soluble, when decomposing formaldehyde in water, powdery or liquid formaldehyde decomposing agent is sprayed into water or a solid block containing formaldehyde decomposing agent is formed, A method of placing it in water is also possible.

次に、本発明であるホルムアルデヒド分解剤の作用効果を確認するために行った実験について説明する。
本発明に係るホルムアルデヒド分解剤を次の手順で製造する。
糞を６０〜１５０℃で５時間の高温処理した後、粉砕し、糞１００ｇに対し１〜１０ｇのバチルススパリカス（Bacillus sphaericus）微生物菌を添加し混合する。
混合粉体１ｇに対し１０ｍｌの水を添加し、実施例１の液体状のホルムアルデヒド分解剤を製造した。
次に、実施例１のホルムアルデヒド分解剤１０００ｇを、吸水ゲル化剤（商品名：Ｋ１ゲルー２０１Ｋ，製造社名：株式会社クラレ）５０ｇに対して吸収させ、実施例２のゲル状のホルムアルデヒド分解剤を製造した。 Next, the experiment conducted in order to confirm the effect of the formaldehyde decomposition agent which is this invention is demonstrated.
The formaldehyde decomposition agent which concerns on this invention is manufactured in the following procedure.
After the feces are treated at 60-150 ° C. for 5 hours at high temperature, they are pulverized, and 1-10 g of Bacillus sphaericus microbial bacteria are added to and mixed with 100 g of feces.
10 ml of water was added to 1 g of the mixed powder to produce the liquid formaldehyde decomposition agent of Example 1.
Next, 1000 g of the formaldehyde decomposing agent of Example 1 was absorbed into 50 g of a water-absorbing gelling agent (trade name: K1 Gel-201K, manufacturer: Kuraray Co., Ltd.), and the gel-like formaldehyde decomposing agent of Example 2 was absorbed. Manufactured.

実施例１のホルムアルデヒド分解剤を１ｍｌ、実施例２のホルムアルデヒド分解剤を１ｇについて、ホルムアルデヒドの分解性能を測定するため、５リットルテドラーバッグの試験容器内に設置すると共に、容器内のガス量を３リットル、ホルムアルデヒドのガス濃度を１５ｐｐｍに調整し、密閉状態で所定時間放置した。試験室の温度は２０℃であった。
ホルムアルデヒドのガス濃度に係る測定は、２時間後、２４時間後、４８時間後に行った。
また、比較対照として、ホルムアルデヒド分解剤を収容しない場合についても、同様に測定を行った。測定結果を表１に示す。 In order to measure the decomposition performance of formaldehyde, 1 ml of the formaldehyde decomposition agent of Example 1 and 1 g of the formaldehyde decomposition agent of Example 2 were installed in a test container of a 5 liter Tedlar bag, and the amount of gas in the container was 3 liters. The gas concentration of formaldehyde was adjusted to 15 ppm, and left in a sealed state for a predetermined time. The temperature in the test chamber was 20 ° C.
The measurement concerning the gas concentration of formaldehyde was performed after 2 hours, 24 hours, and 48 hours.
As a comparative control, the same measurement was performed for the case where no formaldehyde decomposition agent was contained. The measurement results are shown in Table 1.

Figure 2007302706
Figure 2007302706

表１の結果より、本発明に係る実施例１及び２は、比較例と対比すると、ホルムアルデヒドの分解性能が極めて高いことが容易に理解される。また、実施例１と実施例２とを比較すると、液体の方が比較的早くホルムアルデヒドの分解効果が表れる傾向にあるが、長時間に渡る測定では、ゲル状の分解剤の方が、分解効果が持続していることが窺える。
なお、上記バチルススパリカス（Bacillus sphaericus）微生物菌に代えて、バチルスサブチルス（Bacillus subtilis）微生物菌やバチルスツリュゲナイセス（Bacillus thuringiensis）微生物菌を用いた場合についても、同様に、ホルムアルデヒドの分解効果を有することが確認できた。 From the results of Table 1, it can be easily understood that Examples 1 and 2 according to the present invention have extremely high formaldehyde decomposition performance as compared with Comparative Examples. In addition, when Example 1 is compared with Example 2, the liquid tends to exhibit a formaldehyde decomposition effect relatively quickly. However, in the measurement over a long period of time, the gel-like decomposition agent is more effective than the decomposition effect. It can be seen that is sustained.
In addition, in the case of using Bacillus subtilis or Bacillus thuringiensis, instead of the Bacillus sphaericus microbial, the formaldehyde It was confirmed to have a decomposition effect.

本発明によれば、安全性の高い微生物菌を使用しながら、製造コストを抑制し、生産時又は使用時において全く無公害で環境や人体に影響を与えず、使用時においても持続性があり、さらには効率的にホルムアルデヒドを分解可能なホルムアルデヒド分解剤及びその使用方法を提供することが可能となる。
According to the present invention, while using highly safe microorganisms, the manufacturing cost is suppressed, there is no pollution at the time of production or use, it does not affect the environment or the human body, and it is durable even during use. Furthermore, it is possible to provide a formaldehyde decomposing agent capable of efficiently decomposing formaldehyde and a method for using the same.
