Description

니코틴 분해활성이 있는 신규한 균주 {Novel microbacteria having the nicotine degradation activity}Novel microbacteria having the nicotine degradation activity

본 발명은 니코틴을 고효율로 분해하는 활성이 있는 신규한 균주에 관한 것이다. 보다 상세하게는, 본 발명은 기존의 화학적 처리 또는 생물학적 숙성에 의한 니코틴의 처리 방법에 비하여 니코틴 분해능이 우수하고, 대량으로 배양하여 니코틴의 분해 목적에 이용할 수 있기 때문에 저니코틴의 담배를 대량으로 생산하는데 유용하게 이용할 수 있으며, 담배 폐기물의 처리 시 2차 폐기물을 생성하지 않아 환경적으로도 안전하게 이용할 수 있는 니코틴 분해활성이 있는 신규한 균주에 관한 것이다.The present invention relates to a novel strain having the activity of breaking down nicotine with high efficiency. More specifically, the present invention has a superior nicotine resolution compared to conventional methods for treating nicotine by chemical treatment or biological aging, and can be used for the purpose of nicotine degradation by mass cultivation, thus producing a large amount of low nicotine tobacco. The present invention relates to a novel strain having nicotine degrading activity, which can be usefully used and does not generate secondary waste during the treatment of tobacco waste and can be used safely in the environment.

담배에는 인체에 치명적인 30여 가지의 유독성 물질이 함유되어 있는데, 암 유발인자로 밝혀진 타르성분 및 니코틴이 대표적이다. 특히, 니코틴은 중독성이 강하여 흡연자들이 금연하기 어려운 원인이 될 뿐만 아니라, 자체 독성이 매우 강하여 흡연자들의 건강을 해치는 주범이다. 이에, 흡연으로 인한 질병문제가 사회적인 문제로 크게 부각됨에 따라 니코틴 함량이 낮은 순한 담배에 대한 선호도가 상승하게 되었다.Tobacco contains about 30 toxic substances that are fatal to the human body, and tar and nicotine are known to be cancer causing factors. In particular, nicotine is a highly addictive cause not only difficult for smokers to quit smoking, but also has a very strong self-toxicity, which is a major culprit for the health of smokers. Accordingly, as the disease problem caused by smoking has been highlighted as a social problem, the preference for mild tobacco having low nicotine content has increased.

이러한 요구를 충족시키고 흡연자들의 건강을 개선시키고자 저니코틴의 담배를 생산하기 위한 다양한 시도가 있어 왔다. 등록특허 제10-289111호에는 물과 술의 혼합액에 담배잎을 침지하거나 분무한 다음 증자 및 건조시킴으로써, 니코틴, 타르 및 기타 유독 성분의 함량이 저하된 담뱃잎을 가공하는 방법이 공지되어 있으나, 상기 발명은 니코틴의 함량은 감소시킬 수 있으나 담배의 상품 가치를 떨어뜨리는 단점이 있다. 등록특허 제10-0217828호에는 잎담배 추출물을 알칼리 수용액으로 처리하고 이를 유기용매로 분획 추출하여 니코틴을 제거한 저니코틴 담배 추출물의 제조방법이 공지되어 있으나, 그 공정이 복합하여 이용하는데 어려움이 있다. 또한, 공개특허 제2001-100113호에는 엿기름을 담뱃잎에 첨가하고 숙성시키는 방법에 의하여 제조된 기호성이 뛰어난 담배의 제조방법이 공지되어 있으나, 이 방법은 미생물을 이용한 생물학적 처리방법이기는 하지만 선별된 고활성의 니코틴 분해 균주를 이용한 방법이 아니기 때문에 대량으로 제조하는데 어려움이 있으며, 그 효율 또한 떨어지는 단점이 있다. 이에, 니코틴의 함량이 낮아 흡연 시에도 안전한 저니코틴 담배의 대량 제조에 대한 요구가 크게 증대되고 있는 실정이다.Various attempts have been made to produce tobacco of low nicotine to meet this need and to improve the health of smokers. Patent No. 10-289111 discloses a method of processing tobacco leaves having a reduced content of nicotine, tar and other toxic components by dipping or spraying tobacco leaves in a mixture of water and liquor and then increasing and drying the tobacco leaves. The invention can reduce the content of nicotine but has the disadvantage of lowering the value of tobacco products. Patent No. 10-0217828 discloses a method for preparing a low nicotine tobacco extract, in which a leaf tobacco extract is treated with an aqueous alkali solution and fractionated with an organic solvent to remove nicotine, but the process is difficult to use in combination. In addition, Patent Publication No. 2001-100113 discloses a method for producing palatable tobacco prepared by adding malt to tobacco leaves and aging, but this method is a biological treatment method using microorganisms, but it has been selected for high activity. Since it is not a method using a nicotine degradation strain, there is a difficulty in preparing in large quantities, and the efficiency is also disadvantageous. Accordingly, the demand for low-volume manufacturing of low nicotine tobacco, which is safe even when smoking due to the low content of nicotine, has been greatly increased.

이에, 본 발명자들은 기존의 저니코틴 담배 생산 기술에 대한 문제점을 해결하고 저니코틴 담배에 대한 요구에 부응하기 위해 연구한 결과, 연초 제조창의 필터로부터 분리한 본 발명 균주 아스로박터 sp. Nico1이 니코틴을 분해하는 활성이 뛰어날 뿐만 아니라, 종래의 화학적 처리나 효모를 이용한 숙성 처리가 아닌 분리된 고활성의 미생물을 니코틴 분해에 이용하는 간단하고 단순한 생물학적 공정에 의하여 니코틴이 제거된 순한 담배를 제조할 수 있고, 아울러 잎담배 가공 과정 중 생성되는 니코틴 함량이 높은 다량의 고형 폐기물을 안전하게 분해 및 처리할 수 있음을 발견하고 본 발명을 완성하였다.Accordingly, the present inventors have studied to solve the problems of the existing low nicotine tobacco production technology and to meet the demand for low nicotine tobacco, the present invention strain Aslobacter sp. Not only does Nico1 have excellent activity to break down nicotine, but it also produces mild nicotine-free tobacco by a simple and simple biological process that uses isolated high-activity microorganisms for nicotine decomposition rather than conventional chemical treatment or aging with yeast. In addition, the present invention has been found to be capable of safely decomposing and treating a large amount of solid waste having a high content of nicotine generated during the leaf tobacco processing.

따라서, 본 발명의 목적은 니코틴 분해활성이 있는 신규한 균주를 제공하는데 있다.Accordingly, it is an object of the present invention to provide a novel strain having nicotine degradation activity.

본 발명의 다른 목적은 상기 니코틴 분해활성이 있는 신규한 균주를 이용하여 니코틴을 제거하는 방법을 제공하는데 있다.Another object of the present invention is to provide a method for removing nicotine using the novel strain having the nicotine degradation activity.

이하, 본 발명을 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.

본 발명에 따른 신규한 균주는 형태학적 특징, 대사 활성, 탄소원 이용 활성 등의 생리적 특징 및 16S rDNA의 서열분석을 통한 분자생물학적 동정 결과, 아스로박터(Arthrobacter) 속 종균임이 밝혀졌다. 본 발명에서는 이를 아스로박터 sp. Nico1(Arthrobactersp.

In the present invention, this is Asrobacter sp. It was named Nicol ( Arthrobacter sp.

본 발명은 니코틴 분해활성이 있는 상기 균주를 처리함으로써 담배의 니코틴을 제거하는 방법 및 니코틴의 함량이 적은 저니코틴 담배를 제공할 수 있다. 아울러, 고농도의 니코틴을 함유하는 폐기물의 처리 방법을 제공할 수 있다.The present invention can provide a method for removing nicotine from tobacco by treating the strains having nicotine degrading activity and low nicotine tobacco with a low content of nicotine. In addition, a method for treating waste containing high concentration of nicotine can be provided.

본 발명에 따른 니코틴 분해 활성이 있는 신규한 균주는 니코틴을 고효율로 분해하는 특성이 있기 때문에 잎담배 제조 시 사용할 경우 니코틴이 다량 제거되어 안전한 담배를 생산할 수 있고, 균주를 배양하여 담배에 바로 처리할 수 있기 때문에 처리 공정이 단순하여 경제적이며, 담뱃잎 가공 중 발생하는 니코틴 함량이 높은 다량의 고형 폐기물 처리에 이용할 경우 2차 폐기물을 생성하지 않아 안전하게사용할 수 있는 장점이 있다.Since the novel strain having nicotine degradation activity according to the present invention has the property of degrading nicotine at high efficiency, a large amount of nicotine is removed when used in the manufacture of leaf tobacco, so that a safe tobacco can be produced, and the strain can be cultured and immediately processed on tobacco. Therefore, the treatment process is simple and economical, and when used for treating a large amount of solid waste having high nicotine content generated during tobacco leaf processing, there is an advantage that it can be safely used because it does not generate secondary waste.

이하, 실시예 및 시험예를 통하여 본 발명을 보다 구체적으로 설명하고자 하지만, 본 발명의 권리범위가 이들에 한정하는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples, but the scope of the present invention is not limited thereto.

〔실시예 1〕니코틴 분해성 미생물의 분리Example 1 Isolation of Nicotine Degradable Microorganisms

니코틴을 분해하는 미생물 균주를 분리하였다.Microbial strains that degrade nicotine were isolated.

In solid culture, 2.0% agar was added to the medium to prepare a plate medium.

250㎖ 삼각 플라스크에 상기 MSM-니코틴 배지 90㎖를 넣고 여기에 광주 연초 제조창의 Biofilter(담채 상·중·하단, 침출수) 또는 대전 하수 처리장 활성 슬러지로부터 추출한 미생물원을 10㎖ 분주한 후 진탕배양기(shaking incubator)에서 150rpm, 30℃ 조건으로 3일간 배양하였다.90 ml of the MSM-nicotine medium was added to a 250 ml Erlenmeyer flask, and 10 ml of the microorganisms extracted from Biofilter (Tea top, middle, bottom, leachate) or activated sludge in Daejeon sewage treatment plant were dispensed with shaking culture machine. shaking incubator) was incubated at 150rpm, 30 ° C for 3 days.

배지 내의 니코틴이 완전히 분해된 것을 확인한 후 플라스크 내의 배양액 10㎖를 새로운 MSM배지 90㎖에 첨가하여 3회 반복 배양하였다. 미생물의 생장이 확인된 배양액을 MSM배지에서 차례로 희석하고 고체평판배지에 도말하여 30℃에서 배양하였다. 평판배지 위에 미생물의 군집이 성장함을 확인한 후 각각의 콜로니들의니코틴 분해능을 확인하기 위하여 다시 새로운 MSM 배지에 접종하여 배양하였다.After confirming that the nicotine in the medium was completely decomposed, 10 ml of the culture solution in the flask was added to 90 ml of fresh MSM medium, and the culture was repeated three times. The culture medium in which the growth of microorganisms was confirmed was diluted sequentially in MSM medium, plated on a solid plate medium, and cultured at 30 ° C. After confirming that the colonies of microorganisms grow on the plate medium, inoculation was again inoculated in fresh MSM medium to confirm nicotine degradation of each colony.

배양 결과, 도 1 에서와 같이 니코틴 분해활성이 서로 다른 5종의 균주가 분리되었다(도 1의 control은 미생물을 접종하지 않은 MSM-니코틴 배지). 이 중 활성테스트를 거쳐 니코틴 분해활성이 가장 뛰어난 균주 1종을 선발하였다.As a result of the culture, five strains having different nicotine-degrading activity were isolated as shown in FIG. 1 (control of FIG. 1 is MSM-nicotine medium not inoculated with microorganisms). Among them, one of the best strains of nicotine degradation activity was selected through an activity test.

〈시험예 1. 니코틴 분해능 측정〉Test Example 1. Measurement of Nicotine Resolution

용매추출법 및 자외선 흡광도 측정법을 약간 변형한 방법을 사용하여 상기 실시예 1에서 동정한 니코틴 분해활성이 있는 본 발명 균주의 니코틴 분해능을 측정하였다.The nicotine degrading ability of the strain of the present invention having nicotine degrading activity identified in Example 1 was measured using a slightly modified method of solvent extraction and ultraviolet absorbance measurement.

상기 동정한 본 발명 균주 배양액 10㎖을 시험관에 넣고 10% 트리클로로아세트산(trichloroacetic acid) 1.0㎖를 첨가한 후 물중탕에서 5분간 가열하고3000rpm에서 15분간 원심분리하였다. 원심분리된 상등액을 0.5N HCl로 희석한 다음 분광광도계(spectrophotometer)를 이용하여 259㎚에서 흡광도를 측정하여 표준곡선에 의한 니코틴의 농도를 계산하는 한편, 6mM, 9mM, 12mM 및 30mM 농도구배의 니코틴 배지에 대한 본 발명 균주의 세포생장 변화를 시간의 경과에 따라 관찰하여 그 결과를 각각 도 4 및 도 5에 나타내었다.10 ml of the strain culture solution of the present invention was added to a test tube, and 1.0 ml of 10% trichloroacetic acid was added thereto, followed by heating in a water bath for 5 minutes and centrifugation at 3000 rpm for 15 minutes. The diluted supernatant was diluted with 0.5 N HCl, and then absorbance was measured at 259 nm using a spectrophotometer to calculate the concentration of nicotine according to the standard curve, while nicotine with a concentration of 6 mM, 9 mM, 12 mM and 30 mM The cell growth change of the strain of the present invention with respect to the medium was observed over time, and the results are shown in FIGS. 4 and 5, respectively.

도 5를 통하여, 시간이 지남에 따라 본 발명 균주의 생장률이 증가하였으며, 농도 12mM까지는 니코틴의 농도가 증가할수록 생장률이 증가함을 확인할 수 있었다. 그러나 니코틴 분해활성이 있는 본 발명 균주는 30mM의 니코틴 농도에서는 성장이 저해됨을 확인할 수 있었다.5, the growth rate of the strain of the present invention increased over time, it was confirmed that the growth rate increases as the concentration of nicotine increases up to a concentration of 12mM. However, the present invention strain with nicotine degradation activity was confirmed that growth is inhibited at the nicotine concentration of 30mM.

이상에서 설명한 바와 같이, 니코틴을 고효율로 분해하는 활성이 있는 신규한 균주에 관한 본 발명은, 기존의 화학적 처리 또는 생물학적 숙성에 의한 니코틴 처리 방법에 비하여 우수한 니코틴 제거 방법을 제공할 뿐만 아니라, 균주를 대량으로 배양하여 니코틴의 분해 목적에 이용할 수 있기 때문에 저니코틴의 담배를 대량으로 생산하는데 유용하며, 담배 폐기물의 처리 시 2차 폐기물을 생성하지 않아 환경적으로도 안전하게 이용할 수 있는 등의 뛰어난 효과가 있으므로, 담배 제조 산업 및 폐기물 처리 산업상 매우 유용한 발명인 것이다.As described above, the present invention relates to a novel strain having activity that degrades nicotine with high efficiency, as well as providing a method for removing nicotine superior to the nicotine treatment method by conventional chemical treatment or biological aging, It can be used for the decomposition of nicotine by culturing in large quantities, which is useful for producing low nicotine cigarettes in a large quantity. Therefore, it is a very useful invention for the tobacco manufacturing industry and the waste disposal industry.
