Glucose, cellobiose, Avicel, and Solka Floc were utilized as substrates for growth of Thermomonospora sp. in order to study the induction-repression characteristics of its associated cellulase system. While glucose proved to be an effective repressor of the cellulase enzymes, the other three substrates induced relatively high levels of enzyme activity as measured by the filter paper assay. On a unit cell mass basis the highest values of cellulase activity were obtained when Avicel was utilized as the carbon and energy source. The nature of the cellulosic material and its initial concentration were identified as two very important parameters of the induction process.
