Antibacterial and Antifungal potential of acetone, ethanol and methanolic extract of marine red algae Gelidium amansii

Abstract

The marine algae Gelidium amansii is one of the important edible marine red algae having many biomedical applications. In this study, the red algae of Gelidium amansii were analysed for their antibacterial activity and antifungal activity against organisms such as Escherichia coli, Staphylococcus aureus, Bacillus cereus, Micrococcus luteus, Klebsiella pneumonia and Pseudomonas aeruginosa and Candida albicans, Candida tropicalis, Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus. The antimicrobial susceptibility test for the isolates by agar well diffusion method using following acetone, ethanol, and methanol-toluene. The Minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC) and Minimum fungicidal concentration (MFC) using the following extracts. The results are showing the antibacterial and antifungal activity of red algae is good.
