Antibacterial activities of the aqueous extracts of alligator pepper (Aframomum Melegueta) and onion (Allium Cepa) on some bacterial isolates Department: Microbiology By: Rainnjazz Project ID: 6843 Rating: (5.0) votes: 1Rate this project12345 Price:₦4000 Get the Complete MaterialAbstractThe bacterial activity of Aframomum melegueta was tested on Staphylococcus aureus, Escherichia coli (E. coli), Klebsiella species (Klebsiella Spp.), and Salmonella species (Salmonella Spp). Distilled water was used as solvent for the extraction of the plant.The zones of inhibition of the bacterial isolate are 17mm,16.5mm,13mm and 10.5mm respectively. The phytochemcial analysis carried out on Aframomum melegueta revealed the presence of alkaloids, tannins, saponin, steroids, reducing sugar and flavonoid. The presence of these phytochemcials support the use of this plant as antibacterial agent. Aframomum melegueta can therefore be used as antibacterial agent against the groups of bacteria tested. Onion (Allium cepa) is among the oldest cultivated plants and is used for multiple purposes. In addition to its nutritional effects, the antioxidant and antimicrobial activities of onion have also been postulated, and continue to be extensively investigated. Therefore, this study was designed to investigate the possible antibacterial effects of onion on some bacterial isolates. The onion was prepared in water extraction form. Bacterial isolates were tested. These tested bacteria include Staphylococcus aureus, Escherichia coli (E. coli), Klebsiella species (Klebsiella Spp.), and Salmonella species (Salmonella Spp.).The zones of inhibition of the bacterial isolates are 17mm,16.5mm,13mm and 10.5mm respectively. phytochemical analysis carried out on onion extract shows the presence of saponins, flavonoids, reducing sugar and tanins which support the use of onion as an antibacterial agent....Preview Download Preview +Other Microbiology project topics and materials you might be interested in»Isolation and identification of microbes associated with spoilage bread»Bacterial analysis of urine polluted environment in federal polytechnic Nekede, Owerri»Microbiological quality of palm kernel fruits»Microbiological evaluation of home made grape juice»Therapeutic potential of Moringa Oleifera leaves»Antibacterial activity of honey on staphylococcus aureusescherichia coli and streptococcus pyogen isolated from wound»Bacteriological monitoring of abattoirs in Ehime Mbano in Imo state»Phytochemical screening and antimicrobial assessment of Spondias Mombin (Ijikara)»Proximate, selected vitamins, and minerals analysis of Moringa Oleifera»Biodeterioration of natural and artifical stone»Isolation and identification of bacterial aerosols bioaerosols dump sites in Yenagoa»The effect of crude avocado and pawpaw leaves extract on kidney function of guinea pigs»Microbial examination of raw meat obtained at main abattoir, Offa»Isolation and characterization of fungi associated with the spoilage of corn grown in farms in Rukpokwu community»Incidence of staphylococcus and salmonella species in Kunuaya retailed in Yenagoa
