Application of Lignocellulosic Waste Materials for the Production and Stabilization of Trichoderma Biomass

Our study investigated the growth and sporulation of Trichoderma strains in solid-state cultures on lignocellulosic materials and determined the survival and growth dynamics in bio-preparations after biomass drying at 30 degrees C. All waste materials used in the study turned out to be good media for the production of Trichoderma fungal biomass and the highest amount of colony-forming units per gram of dry matter (CFU/g DM), and a number of conidia per gram of dry matter (conidia/g DM) were produced on wheat bran and sugar beet pulp. The drying of biomass had no significant influence on the dynamics of fungal growth. Despite the prolonging of the lag phase and reduction in the maximum specific growth rate, the biomass yield of the analyzed strains was similar to the respective value noted in cultures before drying.
