Abstract:
This study to analyze and follow the composition of the substrate used to
competitively grow certain types of fresh mushrooms in Algeria, such as oyster mushrooms
(Pleurotus ostreatus) and Paris mushrooms (Agaricus bisporus).
The mycelium of the Oyster was cultivated in different substrates (wheat straw, coffee
marc with cardboard, sawdust), In addition to preparing the compote specifically for Agaricus
bisporus. Regarding the yield of the mushroom Pleurotus ostreatus, wheat straw substrate was
found to be the most important compared to other substrates because it is rich in cellulose,
hemicellulose and lignin. On the other hand, the spread of the mycelium of the Parisian
mushroom in the healthy sample in which we placed the gobtage has stopped due to changes
in humidity below 90%and temperature above 19C°.
