Used newspaper is a major component of wastepaper that forms part of waste cellulosic materials which exhibits the potential to be developed as a resource of bio-energy. An initial step in utilizing the bio-energy potential of used newspaper is to bioconvert the cellulose compound into fermentable sugars such as glucose. This step can be performed with a hydrolytic enzyme such as cellulase from A. niger. Various amounts of used wastepaper have been treated with different concentrations of cellulase from A. niger at different incubation temperatures. Optimum degradation was observed at 50 0C with the highest cellulase concentration and during degradation of the highest amount of wastepaper incubated.
Key words: Cellulose, cellulase, newspaper, sugars, bioenergy, A.niger
