Production of Glucaric Acid from a Synthetic Pathway in

A synthetic pathway has been constructed for the production of glucuronic and glucaric acids from glucose in Escherichia coli Coexpression of the genes encoding myo -inositol-1-phosphate synthase (Ino1) from Saccharomyces cerevisiae and myo -inositol oxygenase (MIOX) from mice led to production of glucuronic acid through the intermediate myo -inositol

Preparation of Polyuronic Acid from Cellulose by TEMPO

Various cellulose samples were oxidized by 2 2 6 6 -tetramethylpipelidine-1-oxyl radical (TEMPO)-NaBr-NaClO systems and the effects of oxidation conditions on chemical structures and degrees of polymerization of the products obtained were studied In the case of regenerated and mercerized celluloses almost all C6 primary alcohol groups were selectively oxidized to carboxyl groups and
