ABSTRACT
During this activity, tomato pomace as food industrial waste beside two agricultural wastes dry olive wastes [branches and leaves] and lentil straw as well as combination mixtures of them in a ratio of 1:1 were me starting materials of the current work. After chemical evaluation of the previous wastes, they were subjected to fungal treatment using a strain of white rot fungi [Pleuroteus ostreatus] [10% based on dry weight]. The obtained data revealed an increase in protein content ranged 30- 40% as well as an appearent decrease in lignocellulosic materials [lignin, cellulose, hemicellulose], a fact that is considered to be a promising screen of the use of these treated wastes as applied and useful non traditional feed stuffs. These results were confirmed by in-vitro digestibility determination

The ability of fungi [white rot fungi] to degrade the lingocellulosic substrates was initiated. Two strains of white rot fungi namely, Pleurotus ostreatus and Phanerochaete chrysosporium were used to improve the nutritive value of selected agricultural crop residue namely, maize stalks mixed with an agro industrial waste namely, pea nut husk at different ratios 3:1, 1:1 and 1:3, respectively. After pasteurizing mixtures of maize stalks and pea nut husk at the previously mentioned ratios, they were packed in polyetylene bags then inoculated with two strains of white rot fungi [Pleurotus ostreatus and Phanerochaete chrysosporium] and incubated for 30 days at 28 degree sign C and 35 degree sign C, respectively, using solid state fermentation technique. Results showed that maize stalks and pea nut husk with a ratio of 3:1 decreased lignin content from 10.90 to 100.30% and 7.00%, and increased protein value from 9.75 to 11.73%, and from 11.00 to 13.04%, when combined mixture were treated with Pleurotus ostreatus and Phanerochaete chrysosporium, respectively
