This study aims to check the antibacterial activity of various branded soaps against bacteria that are normally present in the environment. The proposed study includes selection of most common bacterial
strains from the environment. Identification of bacterial strains was done by standard microbiological techniques, which include gram staining, biochemical testing and advanced identification by analytical
profile index. Determination of minimal inhibitory concentration and minimum bactericidal activity of strains was performed by tube and microtitration method. Antibacterial soaps showed better MIC in
comparison with beauty soaps. The most resistant bacterium to all the soaps is Klebsiella pneumoniae and Pseudomonas aeruginosa. It is obvious that antibacterial soaps have the antibacterial agents that
can either kill or inhibit the bacterial cells. It might be possible that some bacterial strains become resistant which leads to their survival even at high concentrations of soaps.
