Waste of Morus alba as the main ingredients in making the cultivation media of oyster mushroom(Pleurotus ostreatus)

Abstract

Morus alba contains cellulose and hemicellulose needed for fungal growth. Besides, this plant also contains high protein wherein the protein required for the growth of fungal mycelium. In South Sulawesi, mulberry waste is also quite widely available, especially waste from feed silkworm's mulberry. This study aims to diversify the cultivation media of oyster mushrooms. The method used in this study is the mixing of raw materials, sterilization of raw materials, inoculation, maintenance, and harvesting. There is five treatment in the blending of raw materials, the use of 100% mulberry waste powder (P1); 75% mulberry waste powder (P2); 50% mulberry waste powder (P3); 25% mulberry waste powder (P4); and 100% sawdust (P5) as a control. The use of 75% mulberry waste powder (P2) produces the best cultivation media. Whereby using this media, it takes 40 days from the growing media inoculating the mushrooms until the oyster mushrooms are ready to be harvested.
