The thermophilic actinomycete, Thermomonospora curvata , released 16‐times the beta‐glucosidase when grown on protein‐extracted lucerne fibre compared with growth on cellobiose or purified cellulose. The intracellular and extracellular betaglucosidases had the same mol. wts (66 kD), but the extracellular enzyme had higher affinities for both p ‐nitrophenyl glucoside and cellobiose and was more resistant to thermal inactivation.
