Antibacterial and Antifungal Abilities of Tacca (Tacca leontopetaloides L. Kuntze) LeafExtraction and its Application in Fresh Mango Preservation

Tacca (Tacca leontopetaloides (L.) Kuntze) is a perennial herb, distributed from West Africa through South Asia to Northern Australia.Tacca leaves, which is 35-40% of the plant's weight are considered a waste product.In this study, the anti-microbial properties of Tacca leaf extract were investigated for their potential use in antimicrobials and fungicides.Tacca leaf extract can be obtained using different solvents including water, diethyl ether, ethyl acetate, and N-butanol.The anti-bacterial ability of the extract was evaluated by the inhibition zone diameter and the minimum inhibitory concentration (MIC) against Pantoea stewartii subsp.Steartii (P.steartii; bacteria) and Aspergillus niger (mold) on the mango skin.The results showed that the n-butanol extract of Tacca leaves had the best antibacterial activity against P. steartii at a concentration of 80%, with an inhibition zone diameter of 0.67cm.The MIC value of the Tacca leaf extract with N-butanol as a solvent against A. niger was 60%.
