RUBIANO FLOREZ, Diego Felipe; CHEGWIN-ANGARITA, Carolina; MELO, Oscar Orlando  and  NIETO-RAMIREZ, Ivonne J.. Comparative study of the production of biomass in surface fermentation and in the liquid state of macromycetes with different nutrient sources. Rev. colomb. biotecnol [online]. 2019, vol.21, n.1, pp.39-46. ISSN 0123-3475.  https://doi.org/10.15446/rev.colomb.biote.v21n1.68869.

Macromycetes have acquired great interest because of their nutritional, therapeutic and economic importance, which is why it is necessary to focus efforts in the search to optimize their biomass production. The present work sought to determine and compare the effect of liquid fermentation (FEL) and surface fermentation (FeSup) (solid medium) on the biomass production of Flammulina velutipes, Hypsizigus tessulatus and Grifola frondosa using six sources of low cost nutrients: soybeans, whole wheat, white corn, precooked yellow corn, wheat bran and ground flax seed. The results of the FeSup allowed to determine that the species with the highest radial growth, indistinctly from the nutrient source, is F. velutipes followed by H. tessulatus and finally G. frondosa. Additionally, the highest biomass production with FeSup is observed for F. velutipes and H. tessulatus (6.4480 g/L and 5.7320 g/L, respectively) On the contrary, for the FEL, G. frondosa (11.4620 g/L) is the species with the highest production. The comparison in the production of biomass using FEL and FeSup, showed that the results are dependent on the culture technique and that the FeSup cannot be used for the preliminary selection of fungi macromycetes, focused on the production of biomass by FEL.
