Combining biocatalysts to achieve new phase change materials. Application to non-edible animal fat
"Formerly known as Journal of Molecular Catalysis A: Chemical" The thermal properties of various alkyl threo-9, 10-dihydroxystearates (DHSEs) prepared from non-edible fat were studied. Non-edible animal fat was hydrolyzed in a 93% yield with R. oryzae resting cells. Crude unsaturated fatty...
