摘要

The fungus Trichoderma asperellum has a great potential to be used as biocontrol agent against plant pathogens in field. For this purpose it is necessary to optimize mass production on an industrial scale. This work proposes a method for the recovery and concentration of T. asperellum spores. The addition of the fertilizer Urfos 44?, decreased pH value of spore suspension from 6.31 to 1.76. This condition allowed spores to flocculate in few hours, rendering a more concentrated suspension by a factor of 6 - 7. Spore viability did not significantly decreased in 72 hours under these conditions. These results will contribute to obtain more concentrated products based on T. asperellum using a fast and low cost method.
