Abstract :The native population of Trichoderma species collected from different habitats was quantified and characterised. The identified strains are T. harzianum insert ignore into journalissuearticles values(IMI-392432, 392433, 392434);; T. pseudokoningii insert ignore into journalissuearticles values(IMI-392431); and T. virens insert ignore into journalissuearticles values(IMI-392430);. Out of five strains, T. harzianum was the most common in all of the habitats. Colony forming units insert ignore into journalissuearticles values(cfu`s); of Trichoderma species varied significantly insert ignore into journalissuearticles values(P = 0.05); in different habitats and were positively correlated with the physico-chemical characteristics of the habitat. Trichoderma was found to have adapted to an acidic habitat. In testing for an efficient bioconversion agent, T. harzianum insert ignore into journalissuearticles values(IMI-392432); was found to be the most effective in kitchen waste decomposition. It provided the highest volume insert ignore into journalissuearticles values(31.80%); and weight insert ignore into journalissuearticles values(30.80%); losses in waste treated with spore suspension. Promising results were also noted using a combined treatment with different strains/species of Trichoderma, which resulted in 18% greater decomposition of waste than the control.
