Trichodermaspp. are filamentous fungi present in nearly all soils and capable of secreting large amounts of cellulase enzymes that candegradecarbohydrate polymer. In the current study, eight isolates of Trichodermaspp. (TC10-RL11, CT11-VO11, CN2-DP11, CN1-DP11, TC9-RL11, CN4-VR11, CK6-VC11, and TC8-RL11) were isolated. Among the eight fungal strains, the CN4-VR11 hadhighly potent CMC degradation with a halo’s diameter zone of 8.7 ± 1.5 cm. The BLAST result indicates that the CN4-VR11 strains and Trichoderma reeseihad a similarity of 98.92% with amax score of 1158 and an E-value of 0.0. The Trichoderma reeseiCN4-VR11 was selectedfor bioproduct production. The application of Trichoderma reeseiCN4-VR11 bioproduct passively increased the efficient decomposition of the organic fertilizers,after only 30 days of incubation, the total organic matter content ≥ 20%was observed to be soft, spongy, and brown-back in color. According to the Government of Vietnam’s Decree No. 108/2017/ND-CP on fertilizer management, dated September 20, 2017, the T5 and T7 treatments were chosen for the production of granular bio-compost, which has a more practical usein agricultural land.
