Gallic acid, a product of tannin degradation, finds application in various fields including biological activities such as antibacterial, antiviral and analgesic. The work was undertaken to produce gallic acid from banana flower stalk and coir pith using fungal system isolated from soil of different places. Optimization of incubaton period for maximum fungal biomass was found to be 6 days and 9 days in banana flower stalk and coir pith amended broth respectively. Five fungal strains were chosen for Gallic acid production and the results reveal that banana flower stalk was found to be the better substrate than coir pith in producing gallic acid and fungal strains C 1 and I2 were found to be better producers than I3, T1 and T3. Therefore it is suggested that agricultural wastes containing tannin could be considered as alternative substrates for Gallic acid production.
