[Asia Economy Yeongnam Reporting Headquarters Reporter Kang Woo-kwon] Korea Maritime and Ocean University announced on the 2nd that a paper co-authored as the first author by student Yoon Ju-bin, who graduated from the Department of Marine Life Sciences and entered the Graduate School of Marine Science and Technology, was published in July in the internationally renowned Scopus-indexed journal ‘Microorganisms.’

Scopus is a global citation index of excellent academic papers created in 2004 by the Dutch publisher Elsevier, and the more citations a paper has, the more authority it gains.

The published paper, titled ‘In vitro Edwardsiella piscicida CK108 Transcriptome Profiles with Subinhibitory Concentrations of Phenol and Formalin Reveal New Insights into Bacterial Pathogenesis Mechanisms,’ analyzed changes in the expression of pathogenic genes that cause disease when E. piscicida, a marine pathogenic microorganism problematic in aquaculture, is exposed to subinhibitory concentrations of major water pollutants phenol and formalin, using RNA deep sequencing technology.

Through this study, Professor Moon Ki-hwan’s team revealed the possibility that environmental pollutants discharged into water environments act as signaling molecules within bacteria, inducing regulation of pathogenicity in disease-causing bacteria, which could cause greater harm to the host.

They also raised the issue of indirect damage caused by low concentrations of environmental pollutants rather than direct damage caused by high concentrations of pollutants commonly occurring in aquaculture.

Professor Moon Ki-hwan said, “The undergraduate research student’s excellent achievement will serve as a great example for other students, and I will put more effort into guiding and researching with the students.”

Meanwhile, student Yoon Ju-bin, having entered the Graduate School of Marine Science and Technology, will continue research from this month as a graduate student on the correlation between environmental pollutants including microplastics and the expression of pathogenic factors in fish disease bacteria.
