Efecto del sustrato y la exposición a la luz en la producción de una cepa de Trichoderma sp.
Effects of substrate and light exposition in the production of Trichoderma sp. In order to evaluate the effect of temperature and lightconditions on biomass production of a Trichoderma sp. strain, three culture media were tested: rice 53% (w/w), rice 53% (w/w) -molasses3% (w/w) and rice 53% (w/w)-mo...

| description | Effects of substrate and light exposition in the production of Trichoderma sp. In order to evaluate the effect of temperature and lightconditions on biomass production of a Trichoderma sp. strain, three culture media were tested: rice 53% (w/w), rice 53% (w/w) -molasses3% (w/w) and rice 53% (w/w)-molasses 10% (w/w) in distilled water. Incubation conditions were: 25°C, constant light and a photoperiodof 24 h light/24 h darkness during 8 days. The evaluated parameters were population density (conidia/mL), spore germination after 24 hoursand purity percentage. The results showed that solid fermentation using rice - distilled water as substrate at 25°C and constant light, allowedthe highest conidia yield (45x1018 conidia/mL), 96% germination after 24 hours, and 92.1% purity. The liquid fermentation rendered a purityof 76.8% and conidia germination of 91.2% after 24 hours, showing a disadvantageous lower purity percentage compared to solidfermentation. |
