Abstract

To study antimicrobial activity of ethanolic extract of maize silk. Staphylococcus aureus, Pseudomonas aeruginosa, Bacillus cereus, Bacillus coli and Candida albicans were chosen as detected germs. Using methods of agar plated diffusions and tube continuous dilution to detect antimicrobial activity and MIC (minimum inhibitory concentration) of ethanolic extract of maize silk. Ethanolic extract of maize silk can inhibit microbial activity against bacteria such as S. aureusP. aeruginosa, B. cereusB. coli and C. albicans and the diameter of bacteriostatic circle is 19, 20, 28, 15 and 21 millimeter, respectively. Ethanolic extract of maize silk has the best antimicrobial activity against Bacillus cereus. The MIC to B. coli is 15.625 mg/ml, while the MIC to S. aureus, P. aeruginosaC. albicans are all the 31.25 mg/ml. Ethanolic extract of maize silk has antimicrobial activity on S. aureusP. aeruginosaB. cereusB. coli and C. albicans.

Key words:Maize silk, ethanolic extract, antimicrobial activity, minimum inhibitory concentration.
