Abstract
Accumulated sawdust is a major waste product produced by numerous active sawmills around the Lagos Lagoon in Nigeria. The potential of this wood waste as a resource for bio-product development through the hydrolysis of its cellulose component into glucose, a fermentable sugar is not yet appreciated. Not only is the environment exposed to this organic pollutant but the health of humans is also at risk. The cellulose content of wood sawdust from five different tropical tree species dumped along the Lagos lagoon has been saccharified with cellulase from Aspergillus niger. In order to increase the amount of fermentable sugars released from the cellulose content the various sawdust samples have been delignified with the Kraft process and hydrogen peroxide treatment prior to A. niger cellulase catalyzed degradation at incubation temperatures of 30 0C, 400C, 500C and 600C, respectively. The delignification process was successful by triggering an increase in sugar formation during cellulase catalyze hydrolyses of all waste cellulose materials with different amounts of sugar produced from the various celluloses.
