Direct Extraction of Fumaric Acid from <i>Rhizopus oryzae</i> Suspensions—Interfacial Mass Transfer

Experimental studies on the reactive extraction of fumaric acid with Amberlite LA-2 from <i>Rhizopus oryzae</i> suspensions using three solvents with different dielectric constants varying from 9.08 to 1.90 (dichloromethane, n-butyl acetate, and n-heptane, respectively) underlined the pa...
