Favolus rugulosus del Neotrópico: primera bioprospección para su valoración en la industria alimenticia.

<p><strong>[Objective]</strong><span style="font-weight: 400;"> Our main objective was to evaluate </span><em><span style="font-weight: 400;">Favolus rugulosus</span></em><span style="font-weight: 400;"> indoor production in different substrates and to analyze the proximal composition of cultivated basidiomata. </span><strong>[Methodology]</strong><span style="font-weight: 400;"> The studied species was identified by morphological and phylogenetic analyses based on ITS markers. Domestication capability was evaluated in different easy-access substrates. Total phenolic content and antioxidant activities were quantified, and proximal content was analyzed on cultivated basidiomata.</span><strong> [Results] </strong><span style="font-weight: 400;">Eucalypts sawdust-straw mixture produced basidiomata in higher yields in an intermediate amount of time (45 days). The highest concentration of phenolic compounds (35.6 ± 2.6 mg GAE g</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;">) and antioxidants (13.6 ± 1.3 mg AAE g</span><span style="font-weight: 400;">-1</span><span style="font-weight: 400;">) were obtained in the ethyl acetate fraction. Regarding proximal composition, </span><em><span style="font-weight: 400;">F. rugulosus </span></em><span style="font-weight: 400;">is composed of 20 % proteins, 15,4 % carbohydrates, 25,2 % dietary fiber and 5,7 % fat. </span><strong>[Conclusions] </strong><span style="font-weight: 400;">Nutritional composition analyses on cultivated basidiomata revealed </span><em><span style="font-weight: 400;">F. rugulosus</span></em><span style="font-weight: 400;"> to be high in protein, carbohydrates, dietary fiber and essential fatty acids.</span></p>
