ABSTRACT
In recent years, there
has been a growing interest in researching and developing new antimicrobial
agents from various sources to combat microbial resistance. Therefore, a
greater attention has been paid to antimicrobial activity screening and
evaluating methods. The research work was conducted to investigate the
antimicrobial activity of ethanolic extract of whole plant of Saccharum spontaneum Linn. (Family:
Poaceae). Disc diffusion technique was used for antibacterial and cup plate
method was used for antifungal screening. Antibacterial
tests were performed by disc diffusion method on nutrient agar, in order to
analyze the percentage zone of inhibition. Whole plant’s extract showed the
significant zone of inhibition (mm), against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and
Pseudomonas aeruginosa. Modified agar well diffusion method was used to
measure the minimum inhibitory concentration (MIC). Antifungal method was
performed by cup plate method against Candida
albicans. Due to presence of tannins, polyphenolic compounds and
flavonoids, it inhibits the growth of bacteria on most regulatory levels.
