ISOLATION, IDENTIFICATION AND ANTIBIOTIC SUSCEPTIBILITY OF Bacillus spp RECOVERED FROM THE HANDS OF APPARENTLY HEALTHY FEMALE UNDERGRADUATE STUDENTS OF OBAFEMI AWOLOWO UNIVERSITY, ILE-IFE.

ABSTRACTThe human hands harbour microorganisms both as part of a person’s normal microbial flora as well as transient microbes acquired from the environment. This study was carried out to isolate and identify Bacillus spp that are associated with the hands of apparently healthy female undergraduate students in Obafemi Awolowo University. The samples were collected using sterile swab sticks dampened into sterile 0.85% normal saline and processed immediately in the laboratory. The isolates we...

Phytochemical Analysis and Antimicrobial Effect of Calotropis procera (Sodom apple) Leaves Extract on Some Bacteria Isolated from Spoilt Nunu Milk.

ABSTRACTThis study was carried to with the aim of determining the antibacterial effect of Calotropis procera against some bacteria isolated spoilt nunu. Bacteria isolated from spoilt nunu were identified based on their Gram characteristics, morphology and biochemical characteristics. Calotropis procera was extracted using ethanol, methanol and distilled water. The ethanol and methanol extracts showed the presence of Saponins, Steroids, Terpenoids, Flavonoids, Tannins, Alkaloids, and Cardiac g...

ANTIMICROBIAL POTENTIAL OF Emericella nidulans AGAINST SELECTED PATHOGENS

ABSTRACT Endophytic microorganisms have proven to be potential sources of antimicrobials against recalcitrant pathogens. Extracts of an endophytic fungus, Emericella nidulans  exhibited antibacterial  activity  against  selected  pathogens.  Emericella  nidulans  was  cultivated  in broth and fermented at 28 ± 2°C for 7days and 21 days to obtain bioactive components. Solvents extraction of bioactive compounds from Emericella nidulans in the ...

The Antimicrobial properties and phytochemicals analysis of Basella alba Linn and Talinum trangulaire against some bacteria and fungi

Medicinal plants have provided a source of inspiration for novel drugs compounds since plant derived medicines have made large contributions to human health. The traditional healers make use of water primarily as solvent but extracts of these plants were certainly much better and powerful. This may be due to the better solubility of the active components in organic solvents (Umadevi, 2011).The phytochemical component of the ethanolic extracts of Basella alba leaf revealed the presence of tann...

Microbiological Evaluation in ilorin Metropolis

ABSTRACT            The presences of pathogenic microorganism in ice cream such as Salmonella Species, Staphylococcus aureus, Escherichia coli have been well documented, but examination of pathogenic bacteria like Bacillus cereus Yersinia enterocolitica, Brucella species and E.coli O157:H7 have been rarely studied. These studies indicated the necessity for a more steady microbial examination of ice cream since ice cream is particularly consumed by children of vulnerable age groups. Ice ...

Antimicrobial screening , nutrients profile and Pyhtochemical analysis of the leaf extracts of Tetrapluera tetraptera

ABSTRACTPhytochemical and Antimicrobial activity of the leaves of Tetrapluera tetraptera using aqueous and ethanolic extract was studied. The leave was observed to be highly rich in polyphenols, flavonoid, reducing compounds and alkaloids. Glycosides, saponins and tanins were present in small amount, there was absence of Phlobotanins, anthraquinones and hydroxyl methyl anthraquinones. In order to confirm the exact concentration of the Phytochemicals present in the leave of T. tetraptera, a GC...

Antibacterial activity of leaf extract of phyllantgus amarus agaice salmonella species coursitive agent of typhoid fever

ABSTRACTThe study was conducted to assess the antibacterial activity of Phyllanthus amarus(Schum and Thonn) extract against Salmonella typhi causative agent of typhoid feverat the laboratories of the Departments of Chemistry and Theoretical and AppliedBiology of the College of Science, Kwame Nkrumah University of Science andTechnology, Kumasi. The objectives were to determine the highest yield of crudeextract of P. amarus using different proportions of water to ethanol and to determinethe sen...

Microbiological Evaluation of Bacteria Species Isolated from Zobo and Kunnu Sold in Olabisi Onabanjo University

ABSTRACTZobo and Kunu drinks are non-alcoholic beverage that is widely produced and consumed in Nigeria.The beverage may possess health risk when contaminated due to method of preparation. Zobo and Kunu drinks were purchased from different sellers in Olabisi Onabanjo University, Ago-Iwoye Ogun State. Physical and chemical analysis of the drinks were carried out, involving pour plate were also employed to isolate bacteria from these drinks. The microbial qualities were determined using pour pl...

Effects of Palm Oil Processing Waste on Soil

ABSTRACTThe microbiological and physicochemical characteristics of soil receiving palm oil processing waste (POPW) in Abraka were investigated. The effect of palm oil processing waste was tested on loamy, sandy and clay soils. The pour plate technique was used for the isolation of the organisms. The total mean bacterial count ranged from 0.91±0.03log10CFU/g to 6.13±0.06log10CFU/g for loamy soil, 0.90±0.02log10CFU/g to 6.09±0.02log10CFU/g for sandy and 0.72±0.04 to 6.0±0.02log10CFU/g for...
