정만영 교수 “미생물 환경내 실제 질산화 활성 비교 확인”
Prof. Jung Man-young’s research findings published in world-renowned journal Efficiency of removing nitrogen pollutants expected to be improved

Jung Man-young, a professor in Jeju National University’s Department of Biology Education, identified the activation of nitrification in the microbial environment.

The university’s research team led by Prof. Jung participated in the multinational joint research project on the comparative analysis of the actual activation of nitrifying bacteria and archaebacteria in the existing environment.

Nitrogen dioxide, a typical greenhouse gas, is often created in the soil or in the ocean due to nitrifying bacteria. The eutrophication of surface water and the contamination of groundwater are also induced by the same bacteria. The joint research teams focused on the fact that the bacteria’s actual activation in the environmental ecosystem had yet to be clarified.

Prof. Jung expected in the paper that his latest research will allow a more in-depth identification of environmental microorganisms, so that an eco-friendly method of ecosystem management can be developed in respond to the global and regional environmental issues.

The paper including the research findings was published in an international journal named ISME Journal (IF 10.302) in July. The paper is titled, “Ammonia-oxidizing archaea possess a wide range of cellular ammonia affinities”.

In recent years, Prof. Jung’s research team has conducted in-depth studies on the roles of microorganisms in material circulation by identifying the physiological, biochemical, and genetic attributes of bacteria in different environmental conditions. The researchers also study on the discovery and application of lactic acid bacteria and effective microorganisms.

Prof. Jung participates in other research projects as a member of the state-funded Stage 4 Brain Korea 21 Incubating Program on Bio-health and Innovative New Medicine Using Sub-tropical Biological Resources.
