Background and Objectives: One of the important strategies for using agricultural waste is to use the biological capacity of medicinal fungi. Agricultural wastes are produced in most parts of Iran as a result of agricultural, horticultural and forestry activities. Every year, thousands of tons of waste materials are burned or thrown away, which leads to environmental pollution and health hazards. The aim of this research is to investigate different substrates (various wastes of agricultural and industrial products) for the cultivation of G. resinaseum. By choosing the right substrate and checking the balanced ratio of carbon to nitrogen in the substrates, it is possible to improve the desired quantitative (performance) and qualitative (nutritional value) traits in G. resinaceum. Materials and Methods: This study was performed in a completely randomized design with 3 replications with Iranian isolate of G. resinaseum in 2020. After collecting the mushroom from the forest, the pure culture of the sterilized basidiocarp was carried out, and then the spawn of the Iranian G. resinaceum was produced. Experimental treatments include 7 types of substrates including 1. Poplar sawdust + Rice bran (90+10) 2. Poplar sawdust + Soybean meal (90+10) 3. Poplar sawdust + Wheat straw (60+40) 4. Poplar sawdust + Rice straw (60+40) 5. Poplar sawdust + Date palm sawdust (70+30) 6. Poplar sawdust + Banana tree waste (70+30) 7. Poplar sawdust (100). Results: The results of this study showed that the highest yield (210.06 g / 2000 g substrate), total dry matter (95.35 g / 2000 g substrate), total polysaccharide (15.95 mg / g dry matter) and Biological efficiency (10.5 persent) of G. resinaseum belongs to the combination of wood chips with rice bran. And the highest amount of total nitrogen of fruiting body (3.67 mg/100 g dry matter) and the protein (22.93 mg/100 g dry matter) is related to the substrate of wood chips with soybean meal. Also, the shortest time for spawn running (28.66 days), pinhead formation (41 days) and precocity (65 days) were recorded for wood chip substrate with rice bran.Background and Objectives: One of the important strategies for using agricultural waste is to use the biological capacity of medicinal fungi.

Grape is one of the most important fruits in the world and despite being nonclimacteric, itsquality decreased rapidly. The main goal of post-harvest technology is to reduce losses during the post-harvest period. Different methods have been proposed to increase the shelf-life of fruits and vegetables, mainly including the use of chemical preservatives that have problems and limitations. Nowadays, demandforusing natural compounds including active edible coatings for keeping fruits quality has increased. This study was conducted to investigate the effect of maltodextrin edible coating containing different concentrations of chitosan and olive leaf extract on shelf-life and qualityattributes (including total soluble solids, fruit juice pH and acidity, flavor index, total phenolic compounds, vitamin C and organoleptic properties) of black grape fruit (Rashehvariety) during 90 days of storage period. Results showed that using maltodextrin coating containing chitosan and olive leaf extract reduced weight loss and prevented the degradation of phenolic compounds and vitamin C of samples during storage period. Increasing storage time resulted in a decrease in the amount of acidity and increased pH of samples, while increasing chitosan concentration and olive leaf extract increased the maintains of organic acids and decreased the pH of grape samples. The amount of total soluble solids in grape samples increased with increasing storage time. Results showed that the use of maltodextrin coating containing chitosan and olive leaf extract maintained the quality and reduced the degradation of the sensory properties of grape fruit during storage period.The best conditions for storing grape fruit include maltodextrin coating containing 2% chitosan and 0.75% olive leaf extract. At these conditions, storage time is about two months (57.30 days) and in this period, grape fruit has the minimum weight loss, but vitamin C and total acceptabilityare maximum, the desirabilityof these optimum conditions is 0.703.
