Abstract

The state-of-the-art of cellulase production in solid state fermentation is presented. It is argued that with appropriate technology, improved bioreactors and operation controls, SSF may be a competitive method for the production of a lignocellulose hydrolysing enzyme - cellulase. Advantages of the cellulase production in SSF are enumerated along with the factors affecting cellulase production. Some typical SSF processes used for cellulolytic enzymes production are also tabulated along with details about substrates, microorganisms and enzymes.
