The biologically active substance is obtained or capable of being obtained by alkaline extraction, using an aqueous solution of at least one base in the presence of at least one reducing agent, of at least one macroscopic edible mushroom reduced to powder, to obtain a mixture having a liquid portion containing the soluble extracted materials and a solid portion formed of insoluble solid particles; filtering the resulting mixture to remove the solid portion and optionally clarifying the liquid portion; neutralising the liquid portion using a cation exchange resin and optionally filtering/clarifying the liquid portion thus neutralised to obtain the biologically active substance in the aqueous phase; and treating the resulting aqueous phase, the treatment being selected from dilution in water, concentration, dehydration and lyophilisation to obtain a biologically active substance which is, respectively, more diluted in water, in an aqueous solution more concentrated, dehydrated in powder form or lyophilised.

Biologically active substance, method for manufacturing same and use thereof as an agent for protecting a biological tissue

Process for conferring a protection against a pathogen upon a plant by elicitation by an aqueous composition, the active agents of which are extracted from edible fungi (parasol mushroom, pleurotus, button mushroom). An alkaline extraction is carried out, then an enzymatic hydrolysis, to obtain a fraction less than 100 kDa. The process consists in spraying the aerial parts of the plant with the composition obtained in this way; this thereby acts to combat cryptogamic diseases of plants such as vines, fruit trees, vegetable crops and cereals.
