현재 물질특허도입 등의 많은 어려움속에서도 이 난관을 헤치고 나아가 생물공학연구개발을 국내에 정착시키고, 2000년대 생물공업분야 세셰시장 10% 점유를 목표로 일로 매진하여야 하는 의무는 정부의 지원체제속에 산.학.연 모두에게 지워진 사명이다. 그러므로 생물공학의 조기 정착화를 위해 대학은 우수인재를 양성배출하고, 지속적인 동관련 기본연구수행과 더불어 기업과의 많은 교류와 서로의 기화를 교환하여 연구과제를 수행해 나감과 공시에 기업은 이를 응용 발전시켜 시대적인 요구에 부응할 수 있도록 심히 노력을 기울여야 한다고 생각한다.

세포나 미생물의 특정 DNA 부위를 증폭하고자 할때 이용되는 PCR(polymerase chain reaction, 핵산중합효소 연쇄반응)은 1983년 미국 Cetus사의 Mullos에 의해 고안되었고, 그후 PCR에 의한 마이코 박테리아의 동정 및 검출이 특정 염기서열의 연구가 이루어지면서 활발히 시도되었으며, 아이젠하크 등은 IS6110을 이용하여 본격적으로 PCR이 결핵균 검출에 유용한 도구로 사용될 수 있다는 가능성을 제시하였다. PCR에 의한 DNA증폭은 단시간 내에 이루어진다는 장점 때문에 유전병 및 미생물의 진단에 이용될 뿐 아니라 법의학 분야 및 장기이식에 따른 조직접합 시험에도 이용될 것으로 예상된다. 이에 따라 국내에서도 결핵연구원에서 최초로 일반 임상검사에 적용함으로써 현재 많은 호평을 받고 있는 PCR에 대하여 알아본다

식품 위생과 관련하여 그 안정성 확보를 위한 새로운 기술로서 수학적 모델을 이용하여 미생물의 생장 변화를 예측하는 예측미생물학분야의 중요성이 최근 크게 대두되고 있다. 수학적 모델은 정성적 분석 결과 및 경험치의 의존도가 높은 HACCP시스템의 단점을 보완함과 동시에 병원미생물의 정량적 위험도 평가를 위한 저비용의 유효수단으로 높이 인정되고 있다. (중략)

Studies based on microbial community analyses have increased in the recent decade since the development of next generation sequencing technology. Associations of gut microbiota with host's health are one of the major outcomes of microbial ecology filed. The major approach for microbial community analysis includes the sequencing of variable regions of 16S rRNA genes, which does not provide the information of bacterial activities. Here, we conducted RNA-based microbial community analysis and compared results obtained from DNA- and its cDNA-based microbial community analyses. Our results indicated that these two approaches differed in the ratio of Firmicutes and Bacteroidetes, known as an obesity indicator, as well as abundance of some key bacteria in gut metabolisms such as butyrate producers and probiotics strains. Therefore, cDNA-based microbial community may provide different insights regarding roles of gut microbiota compared to the previous studies where DNA-based microbial community analyses were performed.

To prepare for the threat of a future epidemic in the post-COVID-19 era, research based on the one-health concept (i.e., the health of humans, animals, and the environment as "one") is essential. Cross-species infections are being identified as a result of the high infection rate and viral load of SARS-CoV-2 in humans. The possibility of transmission of SARS-CoV-2 from humans to mink has been determined. In addition, the transmission of SARS-CoV-2 from humans to cats through contact has been considered possible. The data so far show that livestock and poultry are less likely to be infected with SARS-CoV-2. However, if infections are established through a new mutation, the resulting diseases are expected to have enormous ripple effects on various fields, such as human food security, the economy, and trade. In addition, there are concerns about the endemic prospect of SARS-CoV-2 and the high accessibility of companion animals. This is because the evolution of the virus likely occurs in animal hosts. Once SARS-CoV-2 is established in other species, they might serve as intermediate hosts for the re-emergence of the virus in the human population. Thus, it is necessary to ensure a rapid response to future outbreaks by accumulating research data on the animal infection of SARS-CoV-2. These data can have implications for the development of animal models for vaccines and therapeutics against SARS-CoV-2. Therefore, in this study, epidemiological reviews were analyzed, and response strategies against SARS-CoV-2 infection in animals were presented using the One-health approach.

A number of Bacillus strains are known to have antimicrobial activity useful in various fields. In order to prevent Propionibacterium acnes, which is one of the factors of acne, we selected Bacillus halotolerans F41-3 which have high antimicrobial activities against P. acnes. We conducted complete genome sequencing of B. halotolerans F41-3 and analyzed genomic characteristics. This genome size is 4,144,458 bp with a G + C content of 43.76%, 4,145 total genes and 3,686 protein coding genes. Among the genes, we found that gene clulster of subtilosin, a kind of bacteriocin, synthesis and gene cluster of nickel transportation. Both of them may influence inhibition of P. acnes.

The effects of heavy metal, Cd on the degradation of the herbicide butachlor (N-Butoxymethyl-2-chlor-2',6'-diethylacetanilide) in soils were examined the laboratory. The degradation of the herbicide in soil was greatly inhibited by the amendment of the heavy metal, Cd. The inhibited rate of Cd concentration was high in the order of 30 ppm>20 ppm> 10 ppm>0 ppm. And tile degradation rate of butachlor was high in order of 80 $\mu$M>40 $\mu$M>20 $\mu$M. The effects of Cd on the degradation of the butachlor in soil varied with concentration of heavy metal and butachlor.

The ozone-induced reactivation factor for ozonated or UV-irradiated T3 phage was determined in defferent bacterial strains of Escherichia coli B resistant of sensitive to ozone. Our results suggest that ozone is a weak, if any at all, inducer of the Weigle reactivation, one of the SOS functions. This is in agreement with other studies which have suggested that thes agent is probably a weak inducer of the SOS functions.
