Abstract
AbstractOyster mushroom [Pleurotus ostreatus var. sajor caju (Fr.) Singer] cultivation can play an important role in managing organic waste. It can be cultivated on a wide rang of substrates containing lignin and cellulose. Oyster mushroom was grown on five substrates: Rise straw (Oryza sativa L. var. Alikazemi), Rise straw + Oilseed Rape straw (Brassica napus var. Hyola 401) (75:25 dw /dw), Rise straw + Oilseed Rape straw (50:50 dw /dw), Rise straw + Oilseed Rape straw (25:75 dw /dw) and Oilseed Rape straw alone. Oilseed Rape straw alone and Rise straw + Oilseed Rape straw (25:75 dw /dw) were best for fruit body production of P. ostreatus. Time to fruiting for P. ostreatus was also shorter on Oilseed Rape straw. Protein content of the fruit bodies obtained from Oilseed Rape straw was higher than those from other substrates. Using Oilseed Rape straw as a substrate appears to be suitable for oyster mushroom production.
Highlights
Oyster mushroom [Pleurotus ostreatus var. sajor caju (Fr.) Singer] cultivation has increased during the last decade [1,2]
The type of substrate seemed to affect the time to primordial initiation and the biological efficiency of mushroom production (Table 2)
Biological efficiency in the first flush of production was better for fruiting bodies on oilseed rape straw alone and oilseed rape straw + rice straw (75:25)
Summary
Oyster mushroom [Pleurotus ostreatus var. sajor caju (Fr.) Singer] cultivation has increased during the last decade [1,2]. Commonly grown on pasteurised straw of wheat or rice, oyster mushroom can be cultivated on a wide variety of substrates containing lignin and cellulose. Oyster mushroom cultivation can play an important role in managing and recycling of organic wastes as an alternative to other methods of disposal [3]. Oilseed rape straw is considered to be a kind of wastes and is normally disposed of by burning. This project was undertaken to determine if oilseed rape straw can be used as an alternative to the common straw such as rice and other gramineae straw as a substrate for cultivation of oyster mushroom
