With worldwide caution for the depletion of petroleum resources, research for commodity chemicals derived from biomass has attracted many scientist and industries. In accordance with this global research trend, microbial approach of converting glucose into glucaric acid, which can be a precursor for bio-adipic acid, has been reported. However, microbial oxidation technology has low productivity compared to the high demand of poly amide in industries. This report would like to suggest efficient way of oxidizing C-6 sugar compound, which is abundant in marine biomass, into corresponding diacid moiety. D-glucose and D-galactose was chosen as a substrate. Two different oxidation methods, one with oxygen gas and the other with nitric acid, were tested. As a result, quantitative amount of galactaric acid was obtained from up to 10g of D-galactose via oxidation with nitric acid, but yield was not satisfying when D-glucose was oxidized through O2 bubbling. This can be applied to large scale synthesis of bio-adipic acid, thus realizing the plastic commodity produced from marine biomass. |
