Abstract
The present invention discloses a process for producing erythritol by fermentation using a polysaccharide negative erythritol producing strain and recovering erythritol crystals by direct crystallization from the unrefined micro-organism-free fermentation broth. Direct crystallization of erythritol is performed at dry substance higher than 80% w/w. Recovery of erythritol crystals is at least 85% and purity of erythritol crystals is at least 99% w/w.
