Recent Publications

Prof. Dr. Diana Elizabeth Waturangi, M.Si., is a researcher focused on microbiology and biotechnology, with numerous publications that significantly contribute to the control of fish pathogens and bacteria that cause food spoilage. In 2021, she published several articles exploring antibiofilm activity and the genomic characterization of bacteria and phages.

One of her studies, "Extract from phyllosphere bacteria with antibiofilm and quorum quenching activity to control several fish pathogenic bacteria," discusses the use of bacterial extracts from the phyllosphere (leaves) to control fish pathogenic bacteria. This research highlights the biological potential of these bacteria in addressing pathogenic issues in fisheries.

In another work, "Full-Genome Sequence of Bacillus safensis Strain IDN1, Isolated from Commercially Available Natto in Indonesia," Prof. Waturangi performed a complete genomic analysis of Bacillus safensis, isolated from commercially available natto in Indonesia. This study enhances understanding of this bacterium and its potential applications in the food industry.

Prof. Waturangi also characterized phage genomes in the article "Genomic characterization of bacteriophage BI-EHEC infecting strains of Enterohemorrhagic Escherichia coli." This research is important for developing alternative methods to control antibiotic-resistant pathogenic bacteria.

Furthermore, in the publication "Induction of amylase and protease as antibiofilm agents by starch, casein, and yeast extract in Arthrobacter sp. CW01," she investigated enzyme induction as antibiofilm agents, which could serve as a new strategy for controlling bacterial biofilms.

She also published "Isolation, Characterization, and Application of Bacteriophages Against Several Food Spoilage Bacteria: Bacillus Subtilis, Bacillus Cereus, and Shewanella Putrefaciens," discussing the isolation and characterization of phages that can be used to address food spoilage issues. This underscores Prof. Waturangi's important research in developing biotechnology-based solutions for health and food safety challenges. Through this series of publications, Prof. Dr. Diana Elizabeth Waturangi demonstrates her dedication to addressing issues related to microbiology and its applications in the industry.
