| dc.description | Twelve genera and species of fungi were identified from surface disinfected [0.5% Ca(OCl)2 for 4 min.] mushroom pileus tissue. Overall fungi, Rhizopus sp. (30%) and Monilia sitophila (asexual stage of Neurospora sitophila Shear et Dodge) (10%) were the most frequently recovered species. Aspergillus flavus Link ex Fries, A. fumigatus Fries., M. sitophila and Chaetomium bostrychodes Zopf were found both as internal fungi in the basidiocarps and competitors on sugarcane bagasse mushroom beds. Radial growth reduction of V. volvacea by fungal competitors depended on incubation temperature and the nature of the fungal competitor present. In vitro antagonism was tested for the Chinese straw mushroom and its internal basidiocarp mycoflora. Aspergillus niger van Tieghem caused 100% reduction of mushroom mycelial growth at 27° and 35° C, whereas A. carbonarius (Bainier) Thom caused 62.5% mushroom mycelial growth reduction at 27° C, and 38.8% at 35° C. Generally the internal mycoflora was less antagonistic at 35° C than at 27° C. | en-US |
| dc.description | Se identificaron especies de hongos aislados del basidiocarpo de la seta china, Volvariella volvacea (Bull ex Fries) Sing; las más frecuentes fueron Rhizopus sp. (30%) y Monilia sitophila (etapa asexual de Neurospora sitophila Shear et Dodge), con 10%. De las especies encontradas Aspergillus flavus Link ex Fries, A. fumigatus Fries., M. sitophila y Chaetomium bostrychodes Zopf aparecieron creciendo dentro del basidiocarpo de la seta y sobre la cama de bagazo de caña de azúcar. La reducción del crecimiento radial de V. volvacea por hongos competidores depende de la temperatura de incubación y la naturaleza del hongo competidor presente. Las pruebas de antagonismo realizadas con V. volvacea y la micoflora aislada de los basidiocarpos maduros demostraron que Aspergillus niger van Tieghem causa un 100% de reducción en el crecimiento micelial de la seta a 27° y 35° C, mientras que A. carbonarius (Bainier) Thom causa una reducción de crecimiento miceliar de 62.5% a 27° y 38.8% a 35°; la mayoría de los competidores son menos antagónicos a 35° C que a 27° C. | es-ES |
