Production of glucose-fructose syrups from fermentative hydrolysates of plant wastes

  • Published:
Chemistry of Natural Compounds Aims and scope

Abstract

A method has been developed for obtaining glucose—fructose syrups by the hydrolysis of plant wastes under the action of a complex of cellulases from a hybrid strain of a fungus, followed by isomerization of part of the glucose to fructose by immobilized streptomycete glucose isomerase. The conditions for raising the degree of isomerization of the glucose and the period of half-inactivation of the immobilized glucose isomerase have been optimized, with a simultaneous cheapening of the process. Plant raw materials that have been used for obtaining glucose–fructose syrups are maize cobs, wheat or rice straw, and reeds. Isomerization has been achieved by streptomycete cells immobilized on cotton lint.
