この遺伝子組換え実験には内容に応じて徹底した
バイオハザード防御対策が求められている。 In recent years, with the development of molecular biology and genetic engineering, research that makes full use of genetic recombination technology, for example, cutting the DNA (deoxyliponucleic acid) that carries genetic information in cells, while cutting the DNA of living cells of different species.
These heterologous
By recombining DNA and introducing this recombinant DNA into host cells (such as Escherichia coli), much research is being conducted to create organisms with genes that do not exist in nature. . Along with this, the risk of creating pathogenic microorganisms that did not exist before is increasing, and as a result,
This genetic modification experiment requires thorough biohazard protection measures depending on the content.
また、従来から実施されてきた病原性微生物に

ハザード防御対策は不可欠となつている。 Furthermore, with regard to research on pathogenic microorganisms that has traditionally been conducted, for example, there is research involving highly dangerous pathogens such as those that cause Lassa fever, or research involving unknown pathogens, so biohazard prevention measures are essential. It's summery.

が指定されている（組換えDNA実験指針）。 By the way, the sterilization and disinfection methods currently used in biohazard protection facilities are the high-pressure steam method for laboratory equipment and waste, and the boiling method (130 ml) for wastewater.

にくいという欠点を有している。 However, although the high-pressure steam method can be applied to small-sized items, it is difficult to apply to large-sized items, and furthermore, it is unsuitable for sterilizing or disinfecting containers in which test specimens are contained. The method of boiling waste water also has the disadvantage that it can only be used in small quantities and is difficult to use in large quantities.

その排液の処理が再び必要となつて煩雑である。 On the other hand, fumigating safety cabinets and safety laboratories with formalin requires bringing in separate fumigation equipment, which is not convenient.Furthermore, the sterilizing and disinfecting power of formaldehyde is relatively weak.
It requires high-concentration and long-term treatment, including exposure to 7,000 ppm formaldehyde for 60 minutes. Furthermore, formaldehyde after sterilization and disinfection is often released into the atmosphere, which poses a problem in terms of the toxicity of formaldehyde, and even if formaldehyde is removed by absorption into water,
The waste liquid must be treated again, which is complicated.
これらの理由からこのホルマリンくん蒸による
安全キヤビネツト、安全実験室のバイオハザード
防御は必ずしも満足しうる方法とはいえない。 For these reasons, biohazard protection of safety cabinets and safety laboratories using formalin fumigation is not necessarily a satisfactory method.

の欠点を有している。 Furthermore, ultraviolet irradiation, which is used in conjunction with supplementary sterilization and disinfection, is not effective against the shadow parts of objects, and if the container containing the test specimen is glass, there is a risk of destroying the test specimen. It has some drawbacks.

目し、本発明を完成するに至つた。 In order to overcome such drawbacks, the present inventors
As a result of intensive research into the development of new biohazard protection devices that are easy to operate and effective, ozone has excellent sterilization and decomposition power against biohazard agents, and can be easily produced from air and electricity. Moreover, it is easy to control, and if it is used to sterilize and disassemble it, it can be automated in both atmospheric and water systems and is easy to operate.
Residual ozone can be removed with activated carbon, and it does not pollute the atmosphere, and since ozone is a gas, unlike ultraviolet light, it does not leave any parts unsterilized or disinfected. The present invention was completed by focusing on the fact that there is no risk of harm to the body.

御装置を提供するものである。 That is, the present invention directly connects an ozone generator to the air inlet of a safety cabinet or safety laboratory, introduces highly concentrated ozone gas into the cabinet or laboratory, and sterilizes and decomposes biohazardous factors therein. In addition, high-concentration ozone gas from the ozone generating unit is separately supplied to the wastewater treatment unit for treating wastewater from the cabinet or laboratory to sterilize and decompose biohazardous factors in the wastewater. The present invention provides a biohazard protection device that is water resistant.

による防御装置である。 The biohazard protection device of the present invention protects against the dangers of recombinant organisms created by making full use of genetic recombination techniques in molecular biology and genetic engineering, or the dangers caused by pathogenic microorganisms, especially viruses. Therefore, it is a powerful sterilization and decomposition defense device that goes beyond the conventional sterilization concept.

らないため、100ppm以上という高い濃度のオゾ
ンを用いることが必要である。 In other words, in conventional disinfection and sterilization of hospital rooms and medical instruments, it is sufficient to weaken the action of bacteria to the extent that no harmful effects can be observed, so even when using ozone, it is necessary to use ozone at a low concentration of 30 to 40 ppm. However, in biohazard protection devices, the cell membrane, envelope, and capsid of biohazard factors are destroyed. The DNA containing the genetic information inside was destroyed and destroyed.
Since the DNA must be treated until it becomes irreproducible, it is necessary to use ozone at a high concentration of 100 ppm or more.

い。 The ozone used in the device of the present invention can be easily produced from air and electricity, and its control is simple. Moreover, it has superior sterilization, decomposition, and biohazard properties compared to the conventionally used formaldehyde. It has inactivating power. For example, in the case of tobacco mosaic virus nucleic acid, the inactivating power of ozone is approximately 1000 times that of formaldehyde.

あることが現在判明している。 On the other hand, regarding the mechanism of gene inactivation by formaldehyde, guanine in nucleic acids,
It is known that amino groups such as cytosine and adenine are converted into mono- or dimethylol derivatives by formaldehyde, but to the extent that nucleobases are simply converted to their analogs, they cannot be repaired by repair enzymes. It has now been found that it is possible to reproduce the original activity.

た。 As a result of investigating the mechanism of DNA destruction caused by ozone, the present inventors found that the destruction is centered on guanine bases, that is, guanine is further decomposed into several types of compounds through the cleavage of the double bond at the 4 and 5 positions. However, we also found that thymine decomposes at a similar rate, eventually leading to molecular chain scission.

あるといえる。 DNA repair is not possible with this DNA destruction mechanism caused by ozone, and therefore, the use of ozone for biohazard prevention measures is extremely effective in terms of the speed and effectiveness of sterilization and inactivation.
