Abstract Mutants of Aspergillus niger were selected according to their ability to grow faster than the parent strain on solid media containing 14% (w/v) sucrose. Among 9 mutants, 4 exhibited significantly increased (〉 20% of control) citric acid production. These mutants exhibited strongly increased activities of two glycolytic enzymes, hexokinase and phosphofructokinase. The mutants took up low concentrations (1%, w/v) sucrose at a comparable rate to the parent strain but exhibited a faster uptake of high (14%, w/v) sucrose concentrations.
