The microorganisms have been widely used for phytohormone production and in bio-control of fungal pathogens. In the present study, T. viride VKF3, a mangrove isolate was used for production of auxin IAA under in vitro condition. T. viride VKF3 yielded a high IAA production of 115 µg mL-1 with 0.5% L-tryptophan. The IAA produced by the isolate was confirmed through Thin layer chromatography (TLC) and High performance liquid chromatographic (HPLC) analysis by comparison with standard IAA. The isolate was also capable of producing extracellular enzymes like cellulase, xylanase along with siderophore production which conditions soil and bioavailability of nutrients. The culture filtrate exhbibited plant growth promotional activity along with enhanced germination percentage. T. viride VKF3 exhibited a maximum inhibition of 82 and 94% was achieved by against fungal pathogens F. oxysporum and A. niger respectively. This report shows a high IAA production using T. viride VKF3 with bio-control potential.
