The aim of this work was to establish the best biotechnology for efficient recycling of fruit tree wastes by using them as growing sources for mushroom species. In vitro experiments were carried out in controlled conditions for the optimal cultivation of Pleurotus ostreatus and P. eryngii to get their carpophores as food and medicinal biomass. There were set up three variants of substrates consisting of lignocellulosic wastes belonging to apricot, pear and walnut trees. After inoculation with pure cultures of mentioned species, the substrates were placed into growth chambers at constant temperature of 23 °C, during the incubation between 15-30 days. The physical and chemical parameters during the period of carpophore formation and development were set up and maintained at optimal levels, depending on each mushroom species. After a period of 30 up to 45 days, the registered results revealed a faster development of carpophores and a better productivity of P. ostreatus in comparison with P. eryngii, but the controlled cultivation of both mushroom species turned out to be an efficient recycling biotechnology to get value-added products.
