title: Growth and cellulase production of Micromonospora chalcae and Pseudonocardia thermophila.
abstract: Beta(1,4)glucosidases and carboxymethylcellulases were demonstrated in both strains when using carboxymethylcellulose as a carbon source for growth. Beta(1,4)Glucosidases appeared mainly as cell-bound activities, whereas carboxymethylcellulases were evenly distributed between the incubation fluids and the cellular fractions. In both microorganisms, glucose appeared to repress biosynthesis of the enzymes, and cellobiose and carboxymethylcellulose acted as inducers of the cellulase complex.
