摘要：

In the present work, the use of low-cost substrates to produce Trichoderma spores was evaluated. Rice, corn bran, and wheat bran were used as solid substrate to grow Trichoderma harzanium sp., Trichoderma viride sp., Trichoderma koningii sp., and Trichoderma polysporum sp. No external nutrient sources were added to the solid substrate that was only moisturized with deonized water, sterilized, inoculated, and cultivated at 30 degrees C for 7 days. Wheat bran showed to be the most suitable substrate to produce Trichoderma spores for all strains that were evaluated. High spore counts were obtained for T. harzianum sp. (28.30 x 10(8)/gds) and T. viride sp. (24.10 x 10(8) spores/gds).
