Day 2 :
Konkuk University, South Korea
Time : 10:00-10:45
Soo-Ki Kim has completed his PhD in Osaka University and Postdoctoral studies in Department of Biology of Purdue University. He is a Professor in Department of Animal Science and Technology of Konkuk University in South Korea. He has published research papers in the field of basic microbiology and development of animal feed additives. He has contributed as a President of Korean Agricultural Microbiology Research Association from 2013 to 2015.
Overuse of antibiotic is still focused on the antimicrobial resistance among zoonotic bacteria that potentially circulate among food-producing animals. Use of antibiotics as growth promoter in animal feeds was banned in the EU (2003) and South Korea (2011). As one of alternative promising ways, probiotics and prebiotics are being supplemented into feed, expecting improved body weight gain, feed conversion and mortality rates of animals. Generally used probiotics include members of Lactic acid bacteria (LAB), Bacillus and yeast. Probiotic should be of host origin, non-pathogenic, withstand processing and storage, resist gastric acid and bile, adhere to epithelium or mucous, persist in the intestinal tract, produce inhibitory compounds and modulate immune response. Animal farms in Korea are usually using probiotics, expecting the enhancement of animal growth performance. Both domestic and foreign products are available and increasing in farmer's demand. I will mention on the probiotics market as alternative antibiotics in Korea.

Keynote: The superior antimicrobial activity of polyvinylpyrrolidone wrapped single walled carbon nanotubes (PVP-SWNTs): Unraveling the anti-physiologic path
Time : 11:05-11:50
Minaketan Tripathy has obtained his Bachelor, Master (Pharmaceutics) and Doctoral degrees in the field of Pharmacy in the year 1998, 2001 and 2006 respectively. After serving different institutes in India as a Teacher, in March 2008, he has joined the Faculty of Pharmacy, Universiti Teknologi MARA, Malaysia as a Senior Lecturer and established the Laboratory of Fundamental of Pharmaceutics. He believes in trans-disciplinary research.
Single wall carbon nanotubes (SWNTs) have attracted the attention of the scientific community because of their versatile character and diverse applications. SWNTs have been exploited in many fields of scientific interest. Though the molecule has demonstrated many capabilities, it suffers in regard to its physicochemical character of poor aqueous solubility because of its super hydrophobicity, which is especially important in regard to the areas involving pharmaceutical life sciences. The functionalization of SWNTs has been reported severally but the involved process can affect their intrinsic properties. The alternate advantageous approach is non-covalent functionalization by polymer wrapping. This presentation shall highlight our work on polymer wrapping, the involved solution chemistry in brief, the probable mechanism (3:1) of polymer wrapping and related impact in microbiology. The superior antimicrobial effect of PVP-SWNTS than those of SWNTs shall be discussed. Besides the conventional antimicrobial activity studies, the impact of antimicrobial agents upon the respiratory chains of the bacterium is a subject of particular interest. The respiration kinetics of E. coli against the PVP-SWNTS shall be presented to unravel the anti-physiologic role. In an attempt to reveal the mechanism of interaction of PVP-SWNTs with the active sites of the different respiratory proteins (Lactate oxidase, LDH, SDHE, NADH oxidae, Glycerol-3-phosphate dehydrogenase and Cytbd Oxidase) of bacterium E. coli, the computational study results shall be presented.
