<P>Enzymatic hydrolysis of cassava peels was evaluated using cellulase and beta-glucanase enzymes and their mixtures at three different enzyme loadings with time. The pH of the medium used for hydrolysis was 5 and the temperature was 50&nbsp;°C. The efficiency of the hydrolysis using beta-glucanase was better than cellulase and glucose recovery of 69&nbsp;% was realised when beta-glucanase dosage was increased to 10&nbsp;% (v/w) at 48&nbsp;h which rose to 73&nbsp;% at 120&nbsp;h, releasing 11.19&nbsp;g/l and 12.17&nbsp;g/l of glucose respectively. Less than 20&nbsp;% of glucose was hydrolysed at 10&nbsp;% (v/w) cellulase at 120&nbsp;h releasing 2.6&nbsp;g/l glucose. The optimum experimental condition for hydrolysis of cassava peel was established at 120&nbsp;h when glucose recovery increased to 88&nbsp;% for enzyme mixture of 5&nbsp;% (v/w) cellulase&nbsp;+&nbsp;10&nbsp;% (v/w) beta-glucanase producing 14.67&nbsp;g/l glucose in the hydrolysate.</P>
