Cellulases and other enzymes are needed for saccharification of plant biomass in the biorefinery industry. Expression, characterization, and eventual large-scale production of known and novel cellulases requires the ability to express and secrete heterologous enzymes in relevant protein production platforms like Aspergillus niger. A method for cloning and expression of genes for these desirable enzymes in A. niger is presented in this Chapter.
