Phytochemical screening and antibacterial activity of ethanol extract of Laurusnobilis(Bay leaf) against S.Aureus and Salmonella species Department:Microbiology By: Klintex001 Project ID: 9245 Rating: (5.0) votes: 1 Price:₦5000 Get the Complete MaterialAbstractThe increasing prevalence of antibiotic-resistant bacterial strains has necessitated the exploration of plant-derived compounds as alternative antimicrobial agents. This study focuses on the phytochemical screening and antibacterial activity of the ethanol extract of Laurus nobilis (bay leaf) against Staphylococcus aureus and Salmonella species. The leaves of Laurus nobilis were collected, dried, and extracted using ethanol as a solvent to obtain the crude extract. Qualitative phytochemical analysis was carried out to identify the presence of bioactive constituents such as alkaloids, flavonoids, tannins, saponins, terpenoids, and phenolic compounds. The antibacterial activity of the extract was evaluated using standard microbiological methods against clinical or laboratory strains of S. aureus and Salmonella spp. The results indicated that the ethanol extract exhibited varying degrees of inhibitory effects on both test organisms, with S. aureus generally showing higher sensitivity compared to Salmonella species. The observed antibacterial activity is attributed to the presence of phytochemical compounds known for their antimicrobial properties, which may disrupt bacterial cell walls, inhibit enzyme activity, or interfere with microbial metabolism. This study suggests that Laurus nobilis possesses promising antibacterial potential and could serve as a natural source for developing new antimicrobial agents. However, further studies involving compound isolation, toxicity evaluation, and clinical testing are recommended to fully establish its therapeutic application....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»Phytochemical screening and antimicrobial assessment of Spondias Mombin (Ijikara)»Bacteriological monitoring of abattoirs in Ehime Mbano in Imo state»Proximate, selected vitamins, and minerals analysis of Moringa Oleifera»Biodeterioration of natural and artifical stone»The effect of crude avocado and pawpaw leaves extract on kidney function of guinea pigs»Isolation and characterization of fungi associated with the spoilage of corn grown in farms in Rukpokwu community»Microbial examination of raw meat obtained at main abattoir, Offa»Isolation and identification of bacterial aerosols bioaerosols dump sites in Yenagoa»Incidence of staphylococcus and salmonella species in Kunuaya retailed in Yenagoa
