Biography

Dr.Osama Ibrahim is a highly-experienced Principal Research Scientist with particular expertise in the field of microbiology, molecular biology, food safety, and bioprocessing for both pharmaceutical and food ingredients. He is knowledgeable in microbial screening /culture improvement; molecular biology and fermentation research for antibiotics, enzymes, therapeutic proteins, organic acids and food flavors; Biochemistry for metabolic pathways and enzymes kinetics, enzymes immobilization, bioconversion, and Analytical Biochemistry. Dr. Ibrahim was external research liaison for Kraft Foods with Universities for research projects related to molecular biology and microbial screening and holds three bioprocessing patents. In January 2005, he accepted an early retirement offer from Kraft Foods and in the same year he formed his own biotechnology company providing technical and marketing consultation for new startup biotechnology and food companies. Dr. Ibrahim received his B.S. in Biochemistry with honor and two M.S. degrees in Microbial physiology/ Fermentation and in Applied Microbiology. He received his Ph.D in Basic Medical Science (Microbiology, Immunology and Molecular biology) from New York Medical College. His research dissertation was on the construction of plasmid for the expression of a fusion protein of VEGF121/ Shiga-like toxin as a therapeutic protein for targeting angiogenesis (cancer treatment). Since 1979 he is a member of American Chemical Society, American Society of Microbiology, and Society of Industrial Microbiology.

Abstract

Prebiotics are the fermentable, non-digestible carbohydrates that stimulate as nutrients the growth and the activity of beneficial bacteria (probiotics) in the digestive system. There are two prebiotics categories: Prebiotics fibers that are naturally occurred in whole grain, broccoli, asparagus, radish, cabbage, etc., and Prebiotics oligosaccharides such as Fracto-oligosaccharide (FOX), Galacto-oligosaccharides (GOS), Xylo-oligisaccharides (XOS), polydextrine etc. These prebiotics oligosaccharides are increasingly added to foods for their health benefits and are not labeled as fibers in the United States. Prebiotics oligosaccharides are synthetically manufactured or extracted from plants in pure forms. Probiotics are the beneficial bacteria in the colon such as Befidobacteria and lactic acid bacteria. These probiotics bacteria assist in the maintenance of the natural balance of micro flora in the digestive system to reduce the effect of the harmful and pathogenic bacteria in the digestive system, suggesting that these probiotics bacteria can prevent gastrointestinal tract from infection diseases and reduce gut inflammation. It is also, assumed that probiotics bacteria strengthen the immune system. Synbiotics are products that contain both prebiotics and probiotics. These symbiotic products have the non-digestible carbohydrates source (prebiotics) and the good bacteria (probiotics) Manufacturing of the major prebiotics oligosaccharides and the impact of synbiotics on gut health will be highlighted in this presentation.
