Resumen
DIAZ-TALAMANTES, César; BURROLA-AGUILAR, Cristina; ESTRADA-ZUNIGA, María Elena y ZEPEDA-GOMEZ, Carmen. Obtaining of β-glucans from wild sporomes and in vitro mycelium of Lycoperdon perlatum. Sci. fungorum [online]. 2021, vol.52, e1409. Epub 09-Mayo-2022. ISSN 2594-1321. https://doi.org/10.33885/sf.2021.52.1409.
Background:
Lycoperdon perlatum is a wild edible mushroom traditionally valued as a nutritious food with therapeutic and medicinal properties with biotechnological potential.
Objectives:
The aim of this study was to evaluate the production of β-glucans from mycelium grown in vitro and from sporomes of wild Lycoperdom perlatum.
Methods:
Mycelium was cultured in vitro by liquid state fermentation (LSF), while wild sporomes were collected from a forest of Pinus and Abies. The biomass of both fungal materials was dried and processed to extract the β-glucans by successive extraction in aqueous and alkaline solution. The extracts were subsequently purified and characterized by Fourier transform infrared spectroscopy (FTIR).
Results and conclusions:
The sporomes presented a higher concentration of β-glucans, with 13.80 g of total β-glucans per 100 g of dry biomass, of which, 2.36 g correspond to an aqueous fraction and 11.58 g correspond to an alkaline fraction. The mycelium presented 11.50 g of β-glucans per 100 g of dry biomass, of which, 1.40 g correspond to an aqueous fraction, and 10.11 g correspond to an alkaline fraction. The FTIR spectrum of the four precipitates show the characteristic bands of a β-glucan.
