First Claim
Patent Images
1. A method for the production of glycerol from a recombinant microorganism comprising:
- (i) transforming a suitable host cell with an expression cassette comprising (a) a gene encoding a NADH-dependent glycerol-3-phosphate dehydrogenase enzyme or a NADPH-dependent glycerol-3-phosphate dehydrogenase enzyme; and
(b) a gene encoding a polypeptide encoding a glycerol-3-phosphatase (EC 3.1.3.21) enzyme;
(ii) culturing the transformed host cell of (i) in the presence of at least one carbon source selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides, and single-carbon substrates, whereby glycerol is produced; and
(iii) recovering the glycerol produced in (ii).
