Tropical Atlantic marine macroalgae with bioactivity against virulent and antibiotic resistant Vibrio

The antibacterial activity of ethanol, methanol, hexane and acetone-based extracts of the macroalgae Padina gymnospora (PG), Hypnea musciformes (HM), Ulva fasciata (UF) and Caulerpa prolifera (CP) was investigated. The disk diffusion method was used to evaluate the algae antimicrobial effect against...
