ABSTRACT
A wide variety of waste resources are available on our planet. Egg shell waste is available in huge quantities from the food processing, egg breaking, and the hatching industries. Calcium plays a vital role in Neurospora crassa hyphal growth. Batch experiments have been performed using pure calcium salt as well as calcium in the form of pretreated egg shell waste in concentrations of 0.4, 0.8, and 1.2 g/l, under wheat branbased solid state fermentation by Neurospora crassa at 30ºC with initial pH 6.0. The present paper describes the utility of wheat bran and egg shell waste in cellulase production. The utilization of economically cheap and abundantly available egg shell waste for cellulase production could be a novel and valuable approach in solid waste management.
