Abstract
Synthesis of polygalacturonases in alkalophilic Bacillus sp. which is sensi tive to rifampin, was clearly repressed by glucose. Mutants resistant to gl ucose catabolic repression were selected. From spontaneous mutants, NTT33-c s52 and NTT33-cs301 produced polygalacturonase activities 57.2 to 82.4% hig her than the wild type. (C) 2000 Elsevier Science Inc. All rights reserved.
