Collagen hydrolysis by a new Streptomyces species

A soil streptomycete hydrolysed collagen extracted from bovine Achilles tendon, calf skin, carp swim bladder and rat tail tendon. Enzyme activity was highest with rat tail tendon collagen as substrate. The taxonomy of the streptomycete was studied according to internationally approved methods. Comparative studies revealed that it resembled Streptomyces humidus , S. rochei and S. distatochromogenes in some respects, but differed in many cultural and physiological characteristics. Based on these differences the organism was given a new identity as Streptomyces species A.
