Abstract: The present disclosure describes a method of producing allulose from fructose with a novel psicose-3-epimerase enzyme from a Burkholderia species. Once identified and isolated, the psicose-3-epimerase gene was cloned into a novel production strain and evaluated in both benchtop and pilot scale production environments. Evaluation of the in vivo enzyme activity and downstream processing involves immobilization of the enzyme on solid matrix resins, which is discloses herein.

Abstract: Esters and a process for making esters from organic acids by means of reacting a carboxylic acid with dialkylcarbonate in an alcohol-containing solvent without any extrinsic acid or base catalyst is described. A benefit of the preparation process is that it can make the separation and extraction of ester products simpler and more facile vis-à-vis conventional isolation techniques.
