High Cell Density Strategies and Adaptive Evolution for Microbial Propionic Acid Production
Propionic acid (PA) is a naturally occurring short chain fatty acid produced by microbial fermentation of the indigestible foods in the intestine, having a positive effect on the gastrointestinal health. PA inhibits the growth of pathogenic bacteria and molds; hence it is widely used as preservative for food, feed and grains. It is also used as a component in several industrial products like polym
