Analyse et suivi concurrentiel de la composition du substrat sur la myciculture de quelques champignons de couche frais en Algérie

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°.
