oyster mushroom cultivation
Oyster mushrooms, the common name for the species Pleurotus ostreatus, are one of the most common types of cultivated mushrooms in the world. Also referred to as Dhingri in India. The oyster mushroom is one of the most suitable fungal organism for producing protein rich food from various agrowastes without composting.
Substrate preparation
The popular methods of substrate preparation are as follows:
1) Steam pasteurization:
In this method pre-wetted straw is packed in wooden trays or boxes and then kept in a pasteurization room at 60-80C for few hours. Temperature of the pasteurization room is manipulated with the help of steam through a boiler. Substrate after cooling at room temperature is seeded with spawn. The entire process take 3-5 days.
2) Hot water treatment:
The substrate after chopping (5-10 cm) is soaked in hot water (65 to 70°C) for one hour or 60 to 120 minutes at 80C or in case of paddy straw at 85C for 30-45 minutes. After draining excess water spawn is added. The leached water contains a lot of soluble sugars and phenolic compounds. Hot water treatment makes the hard substrate like maize cobs, stems etc. soft so the growth of mycelial takes place very easily. This method is not suitable on large scale commercial cultivation.
