Comprehending and Domesticating of Wild Growing Turkey Tail Mushroom (Trametes versicolor) from Ethiopia on augmented agro-industrial byproducts

Résumé

Abstract Despite being one of the most studied white-rot fungi, nothing has been done to discover and domesticate Ethiopia's high-yielding wild Trametes versicolor. Thus, this study was initiated to evaluate the growth performance of T. versicolor on growth media. Accordingly, ten substrates (S1–S10) were formulated by a combination of agroindustrial by-products that mainly constituted sugarcane wastes and animal manures. The effect of substrates on yields, biological efficiencies, and nutritional compositions was examined. The mushroom developed a white, cottony mass on the growth media. T. versicolor cultivated on the S5 combination of 80% sugarcane bagasse, 12% horse manure, and 8% poultry manure had the highest yield (158.33 g/500 g bag) and biological efficiency (31.5%), which had an optimum 31:1 C:N. It has shown good mycelial growth, short colonization, and short pinhead formation time compared to other substrates. Low biological efficiency and yields of 11.50% and 57.67% were obtained from S7, which was not supplemented with nitrogen sources. The content of crude protein, fiber, low fat, and carbohydrates were in the range of 7.46–14.65%, 12.89–18.38%, 0.42–0.53%, and 48.75–66.75%, respectively. The highest nutritional values were obtained from S5, except for carbohydrates from sugarcane bagasse mixed with cotton seed hull (S8). Thus, S5 was found to be a suitable growth medium for domesticating wild T. versicolor mushrooms, particularly in regions where poultry, horse manures, and sugarcane bagasse are abundantly available. Hence, S5 is an optimum substrate for T. versicolor cultivation to improve productivity and nutritional quality at lower costs.
