Abstract
|
|
|
|
A single phase composter was constructed by modifying the conventional mixer of sawdust for the cultivation of oyster mushroom Pleurotus ostreatus. The machine was designed on the basis of 3-phase-1 system which was controlled in prewetting, pasteurization and fermentation processes. In composting 200 ㎏ of straw and cotton waste in the machine, it took 20 minutes in prewetting step and also 10 hours at 65℃ in pasteurization process. Postfermentation by aerothermophiles was completed by treating the compost at 45℃-50℃ for 48 hours which was shorten 24 hours from the conventional method. In the postfermentation at high temperature, forced aeration and/or vigorous mixing process(es) played a great role in the improvement of spawn quality. The growth of mycelium of oyster mushroom was excellent in the culture combinated with 3 parts of surface inoculation and 7 parts of mechanical mixing.
