MYCOTECHNOLOGY FOR VALORISATION OF FRUIT TREE WASTES AS ECO-FRIENDLY AND USEFUL PRODUCTS

Abstract

The main aim of this work was to set up the optimal mycotechnology for valorisation of fruit tree wastes by using them as growing sources for Basidiomycetes mushrooms, in order to get eco-friendly and useful products. In vitro experiments were carried out through controlled cultivation of two mushroom species, Ganoderma applanatum and Ganoderma lucidum, on substrates made of fruit tree wastes. There were set up three variants of substrates consisting of lignocellulosic wastes belonging to apple, plum and cherry trees, mixed with cereal grain wastes, such as wheat and barley bran, which were placed in ceramic trays and metal pots. After thermal sterilization and inoculation with the pure mushroom cultures, the substrates were placed inside growth chambers at the temperature of 23 °, the air flow volume exchanges 3-5 m3/h and the relative humidity content 90-95%, RU. The mushroom growth inside the substrates made of lignocellulosic wastes has followed the controlled biotechnological aiming to minimize the duration of cultivation and maximize the final production eco-friendly materials and biodegradable products.
