Scientists discover sustainable method to produce 1,2,4-butanetriol

Japanese researchers were able to produce 1.7 grams per liter of 1,2,4-butanetriol by genetically engineering a yeast strain for direct fermentation of xylose in rice straw and optimizing the strain's iron metabolism through further genetic modification. The findings, published in Metabolic Engineering, could apply to production of other iron sulfur protein-requiring chemicals.
