Glucose, cellobiose, Avicel, and Solka Floc were utilized as substrates for growth of Thermomonospora species 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 3 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 C and energy source. The nature of the cellulosic material and its initial concentration were identified as 2 very important parameters of the induction process.
