BIO SKETCH

Dr. Mary Ellen Sanders is an internationally recognized consultant in the area of probiotic microbiology. As a consultant, Dr. Sanders works with a variety of food and supplement companies on development of new probiotic products or support of existing probiotic product lines. She has conducted extensive reviews of the technical literature on probiotics, published on the science and marketing of probiotic bacteria, coordinated clinical studies to validate probiotic efficacy, updated the FDA on the topic of probiotics, participated in a working group convened by the FAO/WHO to make recommendations to Codex for guidelines for use of probiotics in foods and assisted numerous U.S. companies in evaluating probiotics as food or dietary supplement ingredients. Recently, Dr. Sanders formed a collaborative business relationship, FunctionalBiotics LLC, with two experts in regulatory affairs (Drs. James Heimbach and George Burdock) to address industry needs such as safety, efficacy, labeling and GRAS determination, related to the introduction of probiotic products to the US market.

Dr. Sanders recently was elected President and Chairman of the Board of a newly formed scientific society, the International Scientific Association for Probiotics and Prebiotics (ISAPP). This is an international, non-profit association of scientists dedicated to advancing the fundamental and applied science of probiotics and prebiotics.

Dr. Sanders' research efforts have focused on strain development of lactic acid bacteria with a primary emphasis on genetic improvement of starter cultures as a scientist in the Biotechnology Group of Miles Laboratories and in vitro characterization and identification of probiotic lactobacilli and bifidobacteria for commercial applications, speciation of lactobacilli and bifidobacteria, evaluation of the effect of probiotics on fecal microecology and tracking specific probiotics through the GI tract as a visiting Research Scientist at the Dairy Products Technology Center at California Polytechnic State University, San Luis Obispo.
