MICROORGANISMS, IN PARTICULAR E. COLI, TRANSFORMED BY A DNA SEQUENCE ORIGINATING FROM C. THERMOCELLUM, COMPOSITIONS WITH CELLULOLYTIC ACTIVITY FROM THE MICROORGANISMS AND PROCESS FOR OBTAINING SAME

摘要

DISTINCT MICROORGANISM OF C. THERMOCELLUM, AEROBIC STRICT OR OPTIONAL, PREFERABLY CONSTITUTED BY E. COLI, TRANSFORMED BY A DNA SEQUENCE ENCODING FOR A CELLULOLYTIC ENZYME, DERIVED FROM THE GENETIC HERITAGE OF THERMOPHILUM STRAINS OF THE CAPE THERMOPHILUM TYPE C. PRODUCE EXPRESSION. /P P THESE MICROORGANISMS MAY, AFTER THE BREAKING OF THEIR WALLS, PROVIDE COMPOSITIONS HAVING CELLULOLYTIC ACTIVITY, PARTICULARLY OF THE ENDO-B-1,4-GLUCANASE TYPE, APPLICABLE TO THE TREATMENT OF CELLULOLIC MATERIALS AT A TEMPERATURE OF THE ORDER OF 50 TO 70C.
