microorganisms, particularly e. coli, transformed by a dna sequence from c. thermocellum from these microorganisms abstammende compositions with cellulolytischer aktivitaet and methods of their manufacture.

摘要

Distinct micro-organism of C. thermocellum, strict or optional aerobe, preferably comprised of E. coli transformed by a DNA sequence coding for a cellulolytic enzyme, issued from the genetic complement of thermophilic strains of the C. thermocellum type and capable of producing the expression thereof. Said micro-organisms may, after breaking their walls, provide compositions having a cellulolytic activity, more particularly of the endo- beta -1,4-glucanase type, applicable to the treatment of cellulolytic materials at a temperature comprised approximately between 50 and 70oC.
