The minimum inhibitory concentrations (MIC) of crude extracts were determined using the tube dilution method. Ethanolic extract showed comparatively higher antibacterial activity (15.66 mm) than that of methanolic and aqueous extract of S. platensis along with their respective MIC values, ranging from 100 to 150 μg mL−1. The aqueous extract had no effective antibacterial activity against the test microorganism. The study suggested that S. platensis may have potential use in aqua feed as an antimicrobial agent of pharmaceutical interest.
