The invention concerns an adjuvant composition obtained in a process comprising the steps of: (i) preparing a nutrient solution and, optionally (ia) transferring the nutrient solution into a fermentation vessel and parallel or prior to transferal, (ib) sterilizing the nutrient solution, (ii) adding a suspension containing fungal spores, in particular spores obtained from cultures of fungal species selected from the group consisting of Penicillium, Acremonium, Tolypocladium, Septoria, Beauveria, Sesquicilliopsis, Claviceps, Phoma, Fusarium, Gibberella, Clitopilus, Saccaromyces, Pichia, and Aspergillus speciesor mixtures thereof, preferably of Penicillium species, in particular Penicillium chrysogenum to the nutrient solution, thus forming a cultivation mixture, (iii) growing the fungal species in the cultivation mixture to form a mycelium, (iv) fermenting the cultivation mixture, preferably under conditions under which the fungal species produce a pharmaceutically active or additive product, in particular antibiotic, citric acid or other fermented product, (v) optionally separating the pharmaceutically active or additive product from the cultivation mixture, the mixture containing the adjuvant composition, (vi) separating the mycelium and/or fungal species or spores thereof from the cultivation mixture, preferably by decanting the cultivation mixture, and/or inactivating the mycelium and/or fungal species or spores thereof in the cultivation mixture to provide the adjuvant composition and uses thereof.L'invention concerne une composition d'adjuvant obtenue dans un procédé comprenant les étapes consistant à : (i) préparer une solution nutritive et, facultativement (ia) transférer la solution nutritive dans une cuve de fermentation et en parallèle ou avant le transfert, (ib) stériliser la solution nutritive, (ii) ajouter une suspension contenant des spores fongiques, en particulier des spores obtenues à partir de cultures d'espèces fongiques choisies dans le groupe con
