Auricularia auricula and Pleurotus ostreatus culture by Leucaena leucocephala sawdust of Java dove’s birdcage waste.

Abstract

Leucaena leucocephala was important material for Java dove’s craft hook of cage manufacturer. Sawdust was wasted by this process. This research was observed the possibility to using these sawdust to culture two valuable mushrooms:  Auricularia auricular, Pleurotus ostreatus by evaluated ratio of Leucaena leucocephala and Hevea brasiliensis sawdust (100:0, 80:20, 50:50, 20:80 และ 0:100, respectively). The mix sawdust was fermented 30 days. The organic chemicals of fermented sawdust were tested before it was packing in 1-kg plastic bag. The result show that pH is 7.9-8.5. Ash, moisture and protein were varies by environment. Mycelium was incubated in dark room at room temperature for 30 days. Next, mushroom harvesting was observed at 30 days and 60 days after mycelium incubation. The growth of two mushrooms were recorded. The ratio mix sawdust was significant difference on fresh weight, size of mushroom of Auricularia auricula.  The healthy mushrooms were growth on the ratio of Leucaena leucocephala sawdust more than 50% (the fresh weight is 268 grams/group and size is 15.7 cm.). Whereas the ratio mix sawdust was significant difference on number of mushroom/bag and size of Pleurotus ostreatus, Its healthy growth on the ratio of Leucaena leucocephala sawdust less than 50% (the fresh weight mushroom is 12.7 per bag and size is 10.4 cm.). Therefore Leucaena leucocephala sawdust of Java dove’s cage processed waste can use as material for mushroom spawn culture but the appropriate ratio depends on the kind of mushroom.
