Paper pulp modification and deinking efficiency of cellulase-xylanase complex from Escherichia coli SD5.

Ligno-cellulosic enzymes like cellulase and xylanase have potential for modification of paper pulp characteristics. A low molecular weight cellulase - xylanase complex (14KDa) was co-produced using Escherichia coli SD5. Co-existence of these enzymes was found to be advantageous in paper pulp modification and in deinking applications.

Modeling and structural analysis of cellulases using Clostridium thermocellum as template.

Cellulase is one of the most widely distributed enzymes with wide application. They are involved in conversion of biomass into simpler sugars. Cellulase of Trichoderma longibrachiatum, a known cellulolytic fungus was compared with Clostridium thermocellum [AAA23226.
