Cheonan, Korea. One of LIMB's current Ph.D. students, Valerie Diane Valeriano, a Philippine student finishing her doctoral thesis dissertation at Dr. Dae-Kyung Kang's laboratory, orally presented a part of her work entitled, "Probiotic lactobacilli at various levels of gut mucosal protection" at The International Conference of KoSFA and 49th Annual Meeting held last 19th of May 2017 at the Cheonan SangNok Resort.
The International Conference of KoSFA and 49th Annual Meeting was held from the 18th to 19th of May 2017, as part of the 16th Food Safety Week 2017. It was organized by the Korean Society for Food Science of Animal Resources (KosFA), and co-organized by the KonKuk University (BK21+ Animal Food Project Team), Chungbuk National University (Institute of Animal Biotechnology), and Seoul National University (Institute of Animal Science and Technology). The event was also sponsored by the Korean Ministry of Food and Drug Safety. The theme of the conference was "Where to Go? Safety and Quality Assurance of Animal Originated Foods", which provided a platform for both global academic and industrial sectors to reach a consensus on the safety and quality of food products of animal origins.
Ms. Valeriano's oral presentation focuses on the ability of microbes to colonize the mammalian intestine and maintain mammalian gut health. In her presentation, she has presented various ways in which lactobacilli provide protective functions, specifically through probiotic adhesion and host-microbe interactions, which she has observed with her work using the strains Lactobacillus mucosae LM1 and Lactobacillus johnsonii PF01. Both strains were isolated from the swine tract, and have shown good adhesion to both mucus and epithelial cells (porcine enterocyte cells). Both have shown inhibitor activities against Escherichia coli K88 and Salmonella enterica serovar Typhimurium, and are able to inhibit the adhesion of these gut pathogens in vitro. Further, a specific bacterial surface peptide motif (putative Microbe Associated Molecular Pattern, MAMP) was identified by Ms. Valeriano in the strain PF01, that seems to provide protective function through cytokine regulation of inflammatory signalling pathways and in their ability to maintain tight junction integrity. The latter is currently being investigated.

The Yongkyo Kim Award (Best Oral Presentation Award) was presented by Dr. Saehun Kim, the current president of KosFA. Ms. Valeriano also received a 500,000 won (~435 USD) prize as part of the award during the young scientists competition.
