Antibacterial profile of methanolic extracts from ten local ornamental plants against pathogenic bacteria isolated from aquaculture sites

The study was conducted to investigate the antibacterial profile of ten local ornamental plants against pathogenic bacteria isolated from aquaculture sites. The ten methanolic extracts including Snake Plant, Sansevieria trifasciata Prain, Rosy Periwinkle, Catharanthus roseus (L.) Don, Aloe Vera, Alo...
