Derepressed 2-deoxyglucose-resistant mutants of Aspergillus niger with altered hexokinase and acid phosphatase activity in hyperproduction of beta-fructofuranosidase.

Applied biochemistry and biotechnology - 1 Jan 2000

Abstract excerpt

Aspergillus niger NRRL330 produces extracellular beta-fructofuranosidase (Ffase), and its production is subject to repression by hexoses in the medium. After ultraviolet mutagenization and selection, seven derepressed mutants resistant to 2-deoxyglucose (2-DG) were isolated on Czapek's minimal medium containing glycerol. One of the mutants, designated DGRA-1, produced higher levels of Ffase. A considerable...
