“…The results are similar to other studies that presented mushroom growth and morphology in pure culture using different culture media. This proves that this condition influences fungi growth (Sastre-Ahuatzi et al, 2007;Wiriya et al, 2014;Masoumi et al, 2015).…”

Proteases are important commercial enzymes, and among their numerous sources are the Basidiomycetes. The use of proteases in many industrial areas promotes the search for enzymes with new properties. The aim of this study is to produce and characterize peptidases of a biocomposite from mycelial biomass grown in Amazonic tubers. Lentinus citrinus DPUA 1535 and Pleurotus ostreatoroseus DPUA 1720 were cultivated on Dioscorea trifida, Manihot esculenta and Dioscorea alata supplemented with rice bran or manioc flour residue in different proportions. The highest proteolytic activity was determined in the crude extract from P. ostreatoroseus grown in D. alata (DA) without supplementation (142.22 U/mL). The enzymes showed optimum activities at 40°C and pH 7.0; and stability at 50°C and pH 8.0. The proteases were classified as cysteine proteases based on the effect of inhibitors used.

“…mycelium growth in the sorghum cereal medium was not as good as in millet and milled corn. According to Sastre-Ahuatzi et al (2007), such a thing probably happened because the protease enzyme from Pleurotus sp. isolates was low in the sorghum medium.…”

Pleurotus sp. or oyster mushroom is one type of edible mushroom that contains essential nutrients for the human body. This mushroom has been widely cultivated in Indonesia, one of which is Pleurotus sp. from Tasikmalaya. The key to the success of oyster mushroom cultivation is the seeds and growing medium or baglog, while the factors that influence the quality of the seeds include the type of medium. This study aims to determine 1) the effect of the type of seed medium from the type of cereals used on the growth of mycelium Pleurotus sp. from Tasikmalaya, 2) determine the type of seed medium that has the best mycelium growth. This study uses an experimental method with a Completely Randomized Design (CRD). The parameters measured include the main parameters, namely the rate of growth of mycelium Pleurotus sp. from Tasikmalaya on the seed medium. Supporting parameters are the quality of mycelium growth in the seed medium, the proximate value of cereals used for the seed medium. The results of the analysis showed that the medium of cereals used as seeds ready for cultivation could affect the quality of the seeds produced. The seedling medium from milled corn has the best growth of mycelium.

“…La semilla de maíz, ha sido ampliamente usada por los investigadores (Mintesnot et al, 2014), debido a su ubicuidad y fácil manejo. Otros han usado granos de trigo (Silveira et al, 2008), rastrojos de trigo (Sastre-Ahuatzi et al, 2007), mezclas a diferentes proporciones de residuos, 87% torta de semilla de algodón, 10% afrecho de trigo, 1% sacarosa (Yang et al, 2013); cebada (Ríos et al, 2010) y sorgo (Gaitán-Hernández y Salmones 2008). Los sustratos de mayor colonización del hongo son aquellos que tienen mayor contenido de carbohidratos estructurales, como el maíz y el salvado de trigo (Omen et al, 2013).…”

ResumenLa investigación tuvo como objetivo aislar el micelio secundario de Auricularia spp y Pleurotus spp procedente de tres áreas naturales de la región San Martín, así como evaluar el crecimiento en medio agar papa dextrosa y en sustratos estériles a base de residuos agroindustriales. Se obtuvieron 10 aislamientos de micelios secundarios a través de carpóforos desinfectados de Pleurotus spp y otros 10 aislamientos de carpóforos desinfectados de Auricularia spp. La mayor velocidad de crecimiento en Auricularia spp fue de 62,5 µm h -1 (A1) y de 75 µm h -1 (B10) para Pleurotus spp. En una segunda parte del experimento se produjo semilla de las cepas nativas más veloces en granos de maíz esterilizado durante un periodo de incubación de 40 días. La semilla fue inoculada en sustratos estériles a base de residuos agroindustriales. Las cepas A1 de Auricularia spp y B10 de Pleurotus spp desarrollaron mejor en sustrato a base de residuos de pulpa de café, logrando una eficiencia biológica de 30,33% y 18,20%, respectivamente. Se concluye que las cepas nativas A1 y B10 de hongos comestibles pueden ser utilizadas en la propagación de semilla y producción de hongos comestibles, brindando al agricultor una alternativa complementaria de alto valor nutritivo.Palabras clave: Auricularia spp.; Pleurotus spp.; eficiencia biológica; pulpa de café; cascarilla de arroz. AbstractThe objective of the research was to isolate the secondary mycelium of Auricularia spp and Pleurotus spp from three natural areas of the San Martín region, as well as to evaluate the growth in agar potato dextrose medium and in sterile substrates based on agro industrial residues. Ten isolates of secondary mycelia were obtained through disinfected carpophores of Pleurotus spp and another 10 isolates of disinfected carpophores of Auricularia spp. The highest growth rate in Auricularia spp was 62,5 µm h -1 (A1) and 75 µm h -1 (B10) for Pleurotus spp. In a second part of the experiment, seed of the fastest strains was produced in sterilized maize grains during a 40-day incubation period. The seed was inoculated into sterile substrates based on agro industrial residues. The native strains A1 of Auricularia spp and B10 of Pleurotus spp developed better in substrate based on coffee pulp residues, achieving a biological efficiency of 30.33% and 18.20%, respectively. It is concluded that the native strains A1 and B10 of edible fungi can be used in seed propagation and edible fungus production, providing the farmer with complementary food of high nutritional value.
