Abstract:
A process for producing erythritol by fermentation using micro-organisms and recovering erythritol crystals which comprises:a) selecting as, a microorganism, a polysaccharide negative erythritol producing strain which produces less than 1% polysacchrides based on erythritol content, b) preparing a fermentation culture medium, c) adding the microorganism to the fermentation culture medium, d) allowing the strained of microorganisms to grow until at least 50 g/L erythritol is obtained in the fermentation medium, e) removing the microorganism from the fermentation culture medium, f) concentrating the unrefined microogranism free fermentation culture medium to dry substance higher than 80% w/w, g) crystallizing erythritol, and h) collecting erythritol crystals.
