Abstract

Antibacterial and Antifungal activity of rhizome extracts of turmeric was investigated. The present study aimed at comparing the Antimicrobial activity of four turmeric varieties i.e. Prathiba, ErraGunturu, TellaGunturu, ManaPasupu from Andhra Pradesh. Three Gram positive and Gram negative bacteria namely Staphylococcus aureus, Escherichia coli, Bacillus subtilis were subjected to test the antimicrobial activity along with fungi namely Aspergillus niger, Aspergillus flavus,Pencillium crysoginum, Fusarium oxysporium. The ethanolic extracts of rhizomes were subjected to microbial susceptibility assays using agar well diffusion method.Among all four varieties, Prathiba and ErraGunturu varieties had the most inhibitory effect on the growth of all bacterial strains tasted as compared to Tella Gunturu and ManaPasupu varieties. Of the four varieties, Prathiba variety had the mostinhibitory effect on the growth of all fungi strains. Among the four varieties tested, the Prathiba variety was found to be superior for its antimicrobial potential.
