EXTRACTION, PARTIAL PURIFICATION AND CHARACTERIZATION OF CELLULASE FROM Aspergillus fumigatus AND Aspergillus flavus IN SUBMERGED FERMENTATION SYSTEM USING BREADFRUIT HULLS AS CARBON SOURCE
CHAPTER ONE INTRODUCTION Enzymes are the catalysts of biological processes. Like any other catalyst, an enzyme brings the reaction catalyzed to its equilibrium position more quickly than would occur otherwise. An enzyme cannot bring about a reaction with an unfavourable change in free energy unless that reaction can be coupled to one whose free energy change is more favourable (Nelson and Cox, 2000). The activities of enzymes have been ...
