NOVELTY - A salt tolerant oyster mushroom strain Pleurotus ostreatus DH-1012 (deposit No. KCTC 0938BP) is new.    USE - For use in disposing food wastes to make a cultivating compost with food wastes and cultivating edible mushrooms from the compost, in which the remaining mushroom compost is recycled after harvesting the mushrooms as a specialty additive used for bio-feed and organic fertilizer, and manure (claimed).    ADVANTAGE - The novel strain P. ostreatus DH-1012 has salt-tolerant capability and produces high quality mushroom. If the salt-tolerant mushroom strains including the novel strain P. ostreatus are used, environment-friendly treatment of food wastes can be implemented without causing secondary environmental pollution, while keeping sustainable development of natural ecological system. The method of disposing the food wastes using the salt tolerant mushroom strains achieves primary effect such as treatment of food wastes at a low cost and environment-friendly treatment. Mushrooms can be harvested and the mushroom hyphae in the compost remaining after harvesting the composts decompose any compounds in the mixture and foreign objects such as toothpicks, wooden chopsticks, and papers. The mushroom hyphae spread in the mixture results in the specialty additive for specialty bio-feed and organic fertilizer and manure with rich organic and inorganic objects and of a high rate of intestinal absorption. The enhanced economical effects by the specialty bio-feed and organic fertilizer from the compost remaining after harvesting the mushrooms and by cultivated mushrooms can be achieved. The method can treat large amount of food wastes and contributes to recycling the food wastes as economical resources with high profitability by improving specialty bio-feed and organic fertilizer and cultivated mushroom quality and yields.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (a) a method of producing a novel salt tolerant oyster mushroom strain Pleurotus ostreatus DH-1012;    (b) a method of disposing food wastes using salt tolerant mushroom strains comprising a food wastes pre-processing step for forming a suitable compost for mushroom cultivating, and a mushroom cultivating step for cultivating mushrooms by inoculating salt tolerant mushroom strains into the compost and culturing the mushrooms;and    (c) a system of disposing food wastes using salt tolerant mushroom strains comprising a food wastes pre-processing system for forming a suitable compost for cultivating mushrooms, and a mushroom cultivating system for cultivating mushrooms by inoculating salt tolerant mushroom strains into the compost and culturing the mushroom strain in the compost.    DESCRIPTION OF DRAWING(S) - The figure is a block diagram of a process of disposing food wastes using salt tolerant mushroom strains.
