Evaluación del perfil químico de metabolitos secundarios del hongo silvestre comestible Oudemansiella cubensis (Berk. & M. A. Curtis) R. H. Petersen, Nova Hedwigia, Beih.; su cultivo y factibilidad de producción indoor

Abstract

Oudemansiella cubensis es una especie de hongo comestible de la Funga del Paraguay. Este estudio se centró en caracterizar el perfil químico de basidiomas silvestres y producidos “indoor” y la estandarización del proceso productivo. El perfil químico cualitativo de extractos etanólicos indicó la presencia de metabolitos tipo terpenos y esteroles, y negativos para los alcaloides. La concentración de compuestos fenólicos totales, compuestos antioxidantes y actividad antioxidante fue similar para basidiomas silvestres y producidos indoor. El sustrato de cultivo con mayor rendimiento de producción (13,97%) fue la mezcla chala y marlo de maíz en proporción 1/1.

<i>Oudemansiella cubensis</i> an Edible Mushroom from the Neotropics with Biological and Nutritional Benefits

“…The phenolic compound value for wild fruiting bodies found in our work are consistent to those found in literature for O. cubensis from ethanolic extracts (9.98 mg.g −1 GAE) (Veloso et al, 2021). However, the cultivated fruiting bodies was three times higher than the previously obtained value of 10.38 mg.g −1 GAE (Veloso et al, 2021). Additionally, comparing the methanolic extracts for the mycelia and cultivated fruiting bodies, our values were lower than the 2.38 and 3.88 mg g −1 GAE values reported in literature (Pérez-Chávez et al, 2017).…”

“…The cultivated fruiting body extract (36.47 ± 0.51 mg.g −1 GAE) had the highest concentration, followed by the mycelium extract (19.41 ± 0mg.g −1 GAE) and wild fruiting body extract (10.98 ± 0.32mg.g −1 GAE) (Table 1). The phenolic compound value for wild fruiting bodies found in our work are consistent to those found in literature for O. cubensis from ethanolic extracts (9.98 mg.g −1 GAE) (Veloso et al, 2021). However, the cultivated fruiting bodies was three times higher than the previously obtained value of 10.38 mg.g −1 GAE (Veloso et al, 2021).…”

“…Mycelia were produced from the strain FC23 following (Figure 1 d). Additionally, this strain was later used to cultivate fruiting bodies using a sawdust and corn cob substrate per Veloso et al (2021) (Figure 1 b).…”

“…and M.A. Curtis) R.H. Petersen as the most conspicuous and common species in the neotropics (Albertí et al, 2020;Veloso et al, 2021).…”

“…In terms of their potential use in biomedical applications, Oudemansiella species exhibit potent antimicrobial activity against pathogenic yeasts such as Candida albicans, C. glabrata, C. krusei, C. tropicalis and Cladosporium sphaerospermum (Rosa et al, 2003). Moreover, several studies have reported moderate anticancer and antioxidant properties (Acharya et al, 2019;Rosa et al, 2003;Veloso et al, 2021).…”
