Cellulose, a major component of paper products, consists of glucose units linked by means of β-D-1,4-glucosidic bonds. Insoluble cellulose can be hydrolyzed by cellulase, a multi-component enzyme, to produce soluble sugars such as glucose. Paper products form a major section of organic based waste and its saccharification with the cellulase from Penicillium funiculosum has been researched. Optimum pH and temperature values for action of cellulase from P. funiculosum on filter paper (pH 4.5; 55°C), foolscap paper (pH 5.5; 50°C), newsprint (pH 6.5; 55°C) and microcrystalline cellulose (pH 4.5; 50°C) have been determined. The saccharification of these cellulose substrates at optimum pH and temperature values revealed that the cellulase-complex from P. funiculosum is the most active on foolscap paper followed by filter paper, newsprint and microcrystalline cellulose.
