Studies the production of Cellulase from the growing of Aspergillus niger on the date palm leaves.

Abstract

This study had been made to prove the probability at the production of Cellulase enzyme from the growing of Aspergillus niger on nutrient media in different conditions It has been proved that the optimum pH of the nutrient media was 5.0; this media gave activity of 2.8 unit/ml. The optimum temperature of incubation for the productions of the enzyme was 24 C .This temperature gave activity of 2.4 unit/ml .The optimum incubation period was 8 day, this period gave activity 3.2 unit/ml. Butter result had been obtained when using 40% of date palm leaves powder instead of CMC material. This method gave 2.4 unit /ml.
