CitriStim, a novel ingredient based on Pichia guilliermondii yeast
Structure and characterization of the yeast cell as well as the cell wall are crucial to understanding their functionality. Pichia guilliermondii yeast cells are smaller compared to Saccharomyces cerevisiae. As such they provide a greater surface area per unit of weight added to the feed. They are more hydrophobic, which promotes an even distribution in the gut and attracts lipophilic pathogens.
