Solid-state fermentation is an alternative to submerged fermentation to produce antibiotics, monocellular proteins, enzymes, organic acids, biofuels, etc. However, the advantages of SSF in various processes are greater than in submerged fermentation. This technique not only lowers the cost of the process but also makes the product cheaper for consumers. The article describes the experimental application of SSF in wheat straw for the production of mycelial proteins and cellulase enzymes by Trichoderma viride. This actual residue from the agricultural industry was used as a nutritional base by Trichoderma viride in SSF for the production of cellulase enzymes. Growth and enzyme production by Trichoderma viride were evaluated in wheat straw and alkaline treatment wheat straw (wet processing). Growth of the microorganism (biomass content) shows maximum (123.44 mg / petri dish) in comparative alkaline treatment wheat straw (96.36 mg / Petri dish) in wheat straw for 240 hours. The results show that wheat straw residues from the agricultural industry can be used as an inexpensive base (carbon source) for the industrial production of cellulase enzymes by Trichoderma viride.
