METHOD FOR UTILIZING CELLULOSE IN BIOREACTOR CARRIER AIMING AT PRODUCTION OF CITRIC OR GLUCONIC ACID WITH ASPERGILLUS NIGER

摘要

PURPOSE:To improve both colonization ratio of Aspergillus.niger and fermentation efficiency, by using many small pieces consisting of cellulosic fibers having high voids as a carrier for immobilizing the Aspergillus.niger. CONSTITUTION:Raw sugar is fermented with immobilized enzymes of Aspergillus.niger in a bioreactor to produce citric or gluconic acid. In the process, many small pieces consisting of cellulosic fibers having high voids are used as a carrier for immobilizing the Aspergillus.niger.
