ABSTRACT Polyhydroxybutyrate (PHB) are biodegradable materials, which are accumulated to store carbon and energy in various microorganisms. Soil samples used for the study were collected from groundnut farm garden. The isolates were screened for PHB production using sudan III stain as well as submerged fermentation. Four (4) of the best PHB producing bacteria were selected for further study. A total of twenty one (21) bacte...
ABSTRACT The evaluation of power density of ray emissions from GSM masts in selected locations within Ilorin metropolis were carried out. The measurements taken in each spot were done using Acoustimeter. The location that shows the highest peak measurement (5.12 ± 1.07) location H, which exceeded the international approved exposure limits which is 4.1mW/m2. This research shows that there are some areas within Ilorin metropolis where these GSM antennas are installed and is emitting high radi...

ABSTRACT This research was conducted in Microbiology Laboratory of Godfrey Okoye University to determine the antimicrobial efficacy of aqueous, methanol, ethanol of Pisdium guajava and Citrus x sinensis on the pathogenic Streptococcus mutans and Candida albicans. The Dimethyl sulfoxide was used for dissolving the plant extracts. Pisdium guajava showed antimicrobial activity against C. albicans with the exception of methanol showing no zone of inhibition to any of the isolates. The aqueous...
ABSTRACT Global crop and energy production are fast dwindling inversely to population growth. Common bean (Phaseolus vulgaris L.) yield has reduced worldwide due to soil infertility which can be reversed through application of chemical fertilizers. The chemical fertilizers used to ameliorate nitrogen, phoshorus and potassium are expensive and cause both deleterious physico‒chemical modification of soil and water mass eutrophication. The common bean has ability to fix atmospheric nitrogen s...
ABSTRACT Diarrhoeal diseases in Kenya are among the five main causes of mortality in children younger than five years. Bacterial diarrhoea has been reported to account for up to 30 % of all cases of infantile diarrhoea. Among children of age five years and below, diarrhoeagenic E. coli (DEC) such as enterotoxigenic E. coli (ETEC), enteropathogenic E. coli (EPEC), enteroaggregative E. coli (EAEC) are the most important enteric pathogens and are responsible for 30 to 40 % of all the diarrhoeal...
ABSTRACT Petroleum – polluted sites are disturbed ecosystem with scanty plants. Study was carried out in such sites to assess the area of its rhizobacterial status, particularly comparing that of the rhizospheres and non-rhizospheres in the site. The samples were suspended and serially diluted in physiological saline and inoculated on nutrient media by spread plates method. After incubation and isolation, the isolates were characterized by morphological examination, gram staining, biochemic...
ABSTRACT The safety, efficacy and quality of herbal mixtures have been an important concern for health authorities and health professional, especially now there is increase in the use of herbal mixtures. This study was aimed at isolation and identification of microorganisms from some liquid herbal mixtures sold in Enugu metropolis, South East of Nigeria. A total of twenty samples of herbal mixture were selected at random, from herbal shops in Enugu metropolis and were analysed in Microbiol...
ABSTRACT Chlorella vulgaris is an edible microalgae and a highly notorious potential feed resource for many agriculturally important animal species. Chlorella vulgaris intake has also been linked to improvements in animal health and welfare. Its influence over animal development stems from its nutritive and protein-rich composition, thus leading to an increased commercial production to meet consumer demand. The aim of this work is to isolate and identify microalgae used in poultry farming a...
The study was carried out to investigate the effect of aqueous and petroleum ether extract of momordica charantia on blood glucose level of albino rats.The extraction was done using petroleum ether and water .Thirty two albino rats were grouped into eight (A ,B,C,D,E,F,G,H). Comprising of four in each group .Diabetes was induced with a single Dose of 100mg/kg body weight of alloxan solution .After induction of alloxan ,group A and B were orally administered with 100 and 200mg/kg body weight o...
ABSTRACT In the for anti microbial effect the back peel of Persea americana (AVACADO) was investigated for activities . the study was to evaluate the antimicrobial efficacy of the crude ethanolic and aqueous extract of the peel of Persea americana against selected clinical isolates. The agar well diffusion method was used in study also phytochemical screening was conducted on the plant which revealed the presences of saponin, carbohydrates, tannins the present invention relates to e...
ABSTRACT This research work was carried out to examine the physicochemical and phytochemical constituents of honey and Shea butter samples respectively and their antibacterial effect on Staphylococcus aureus and Klebsiella pneumoniae. The physicochemical screening of honey showed that the honey samples used have low water activity, low moisture content, low pH value below 4.0 and Ash while the phytochemical analysis of Shea butter revealed the presence of Saponnins, Tannins, Alkaloids, Stero...
Microbiological tests revealed that Hibiscus sabdariffa plant extract has antibacterial properties thus verifying folklore medicine in the treatment of abscesses, bilious conditions, cough, dysuria and scurvy (Morton, 1987; Perry, 1980 Ross, 2003). The extraction type of aqueous generally had the same potency with cold extracts having a slightly better antimicrobial activity than hot aqueous ex...
ABSTRACT The present experiment aims at investigating the growth behaviour of different yeast strains inselected carbon, nitrogen and stress environment to obtain strains with prospects for industrialapplication. Specifically, the study is set to: isolate yeast from decaying mango fruit anddetermine growth performance of yeast strains in different environments, carbon, nitrogen andstressors. The procedure adopted in the study uses different ...
ABSTRACT In African folk medicine, water infusion of Mangifera indica stem bark are highly valued in thelocal treatment of malaria fever, diarrohea, diabetes mellitus and liver diseases. Various part ofthis plant can also be used in treatment of toothache, dysentery, anemia, hypertension andinsomnia in different parts of the world. This study was described to determine the activities ofthe stem bark extract of M.indica against some panel of bacterial...
