EVALUATION OF SUBSTRATE MIXTURES FOR PRODUCTION OF Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm

Abstract

The pulp of Agave salmiana ssp. crassispina and Agave angustifolia ssp. tequilana var. azul, byproduct of the mezcal industry, was evaluated in different treatments with wheat bran, pine shavings, walnut shavings, cedar shavings and oats straw, used as substrate for the cultivation of Pleurotus ostreatus, determining what mixture is the most adequate to cultivate the mushroom. A bromatological analysis was performed for each treatment at the beginning of the cultivation, determining the variables of moisture, ash, raw fiber, raw protein, lipids, total reducing sugars, as well as quantifying the biological efficiency of P. ostreatus. It was analyzed statistically through the HSD Tukey test, finding that the mixture of pulp of A. angustifolia ssp. tequilana var. azul mixed with 30 % of walnut shavings and 5% of wheat bran obtained a biological efficiency of 33.24 %.
