Mannan: structure, biosynthesis, and methods extraction from yeast Saccharomyces cerevisiae

Abstract

In recent decades, interest in biologically active Mannan-oligosaccharides isolated from yeast, algae, and higher plants have grown. The growth is due to their attractive properties, which have expanded their use and application not only in the food industry but also in medicine and animal feed. Indeed, the yeast extracts sector generates an enormous amount of yeast cell wall (YCW) as a by-product, so increasing attention is being paid to the yeast cell wall (YCW) as a promising source mannan. This review presents various sources of mannan and its structure and highlights the biosynthesis of mannan in S. cerevisiae yeast and its extraction methods.
