: Production by Submerged Culture and Bioactivity Against and .

Among the prospective biocontrol agents, the saprophytic filamentous fungus is an excellent necrotrophic mycoparasite of numerous plant pathogenic fungi. However, its commercial development has been hampered by mass production difficulties during solid-state fermentation. Conversely, the submerged liquid fermentation shortens the cultivation time while increasing yields of fungal propagules.

Optimizing mass production of Trichoderma asperelloides by submerged liquid fermentation and its antagonism against Sclerotinia sclerotiorum.

Commercial products based on Trichoderma are obtained mainly from solid-state fermentation. Submerged liquid fermentation is the most appropriate method compared to the solid medium for large-scale production of Trichoderma spp. The present study aimed to optimize the combination of key variables that influence the liquid fermentation process of Trichoderma asperelloides LQC-96 for conidial production coupled with its efficiency in the control of Sclerotinia sclerotiorum.
