摘要：AbstractThe present study reports the enzyme 1-aminocyclopropane-1-carboxylate deaminase (ACCD) fromTrichodermastrains TSK8 and SKS1 enhance the growth mangroves (Rhizophora) evidenced by primary enzyme quantification followed by greenhouse experiments. The results indicated that ACCD enzyme activity about 20% higher in strain SKS1 than that of strain TSK8. In the greenhouse study, we analyzed the effect ofTrichodermatreatment on physiological and biochemical characteristics of mangrove seedlings. The results demonstrated that SKS1 significantly enhanced the growth of mangroves (Rhizophora apiculataandRhizophora mucronata) as compared to control (untreated). The strain TSK8 and SKS1 increased the plant total biomass by 43.26% and 41.23% respectively inR. mucronata. Particularly, SKS1 showed the 70.8% biomass increase inR. apiculata.The growth was investigated with and without the addition of soluble phosphate were investigated. Thusly, the fungal strains SKS1 and TSK8 derived ACCD has potency on the mangroves growth enhancement. Thus present work provided the platform for the development ofTrichodermasp. based biofertilizer for a promising approach for the restoration of aquatic plants.
