Cellulose is the most abundant renewable natural biological resource, and the production of bio-based products and bioenergy from less costly renewable lignocelluloses materials in form of agro-industrial biological waste. The cost of enzyme production can be significantly reduced if low value biological substrates like fruit processing waste. The cost of lignocelluloses raw material influences the economy of many fermentation processes, hence the cost play a decisive role in future and scope of industries employing fermentation processes. Discarded plant parts like peels of fruits and agro harvest, paper huge waste in the civil area and generate obnoxious odour, can be effectively utilized for the production of cellulase enzymes.  The recognition that environmental pollution is a worldwide threat to public health has given rise to a new massive industry for environmental restoration. Submerged and solid tate fermentation systems have been used to produce compounds of industrial interest from lignocellulose, as an alternative for valorization of these wastes and also to solve environmental problems caused by their disposal. When submerged fermentation systems are used, a previous stage of hydrolysis for separation of the lignocellulose constituents is required. The major constituents of lignocellulose are cellulose, hemicellulose, and lignin, polymers that are closely associated with each other constituting the cellular complex of the vegetal biomass It can be degraded by cellulase enzyme complex and is deceptively simple chemically, a polymer consisting only of glucose linked only by β1, 4 bonds. Cellulase refers to a class of enzymes produced chiefly by fungi , bacteria , and protozoans that catalyze cellulolysis (i.e. he hydrolysis of cellulose ). So with help of valuable microbe agro industrial waste which is rich in lignocelluloses product could be used as media for enzyme production. The review discuss current knowledge on cellulase production by microorganism, and it discusss the industrial application of cellulase and up coming challenge in cellulase research especially in the direction of improving the  process of economies of enzyme production.
