Influence of Different Nitrogen Sources on Growth and Phb Production of Bacterial Isolates

ABSTRACTPolyhydroxybutyrate (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...

Evaluation of Power Density of Ray Emissions From Gsm Masts in Selected Locations of Ilorin Metropolis

ABSTRACTThe 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 ...

Microbiology of Polyethylene-Packaged Sliced Watermelon (Citrullus lanatus) Sold by Street Vendors in Nigeria

AbstractTen packaged, freshly sliced watermelon were collected from different street vendors to determine their microbiological quality. Eight different microbial isolates were obtained from the sliced watermelon samples, namely Escherichia coli, Klebsiella aerogenes, Proteus mirabilis, Staphylococcus aureus, Lactobacillus spp., Saccharomyces cerevisiae, Rhizopus stolonifer and Mucor spp. The effects of high density polyethylene (HDP) and low density polyethylene (LDP) packaging bags on t...

The Assessment of Floral Abundance and Composition of Neni-Nimo Watershed in Anaocha L.G.A. of Anambra State, Nigeria

AbstractThe research was carried out on the floral composition of Neni-Nimo watershed between November 2019 and July 2020. The research work aimed to find out the various plant species that inhabit the watershed, their abundance measures and importance values. In this study, the watershed was divided into three catchment areas, the upper, the middle and the lower catchment. Each of the catchment zones was divided into component parts, with an area of (50 m X 30 m) each. The experiment was lai...

Plasmid Profile Of Streptococcus lactis And Lactobacillus Plantarum Isolated From Ogi Encoding For Acetaldehyde In Yoghurt

AbstractAn investigation was carried out on the plasmid profile of Streptococcus lactis and Lactobacillus plantanum isolated from a total of 120 samples collected from Oyingbo, a local market in Lagos State. Morphological, cultural, physiological characterization and API kits were employed to isolate and identify and treptococcus lactis and Lactobacillus plantanum. All the isolates harboured plasmids ranging from 1-7 in numbers and 3kb – 21.5 kb in sizes. Distinct plasmi...

Identification and Characterization of Lactobacillus Isolates Recovered from Locally Fermented Milk (Nunu) consumed within Lagos Metropolis

ABSTRACTThis work assessed the probiotic potential of “Nunu” using Lactobacillus, a genus of Lactic acid bacteria and a major probiotic organism as the indicator. The viable Lactobacillus counts of samples purchased from six different areas within Lagos Mainland were enumerated by serial dilution and pour plating in selective media, DeMann, Rogosa and Sharpe agar (MRS). Twelve strains of Lactobacillus were randomly selected from the samples and identified by standard morphological, physio...

Anti-Microbial Efficacy of Guava (Pisdium guajava) and Orange (Citrus sinensis) Stems Extract Against Streptococcus mutans and Candida albicans

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 a...

Everything You Need to Know About the Swine Flu Pandemic

IntroductionSwine flu is a human respiratory infection caused by an influenza strain that started in pigs.The World Health Organization uses the term "(H1N1) 2009 pandemic" when referring to the Swine flu event, and officially adopted the name "A(H1N1)pdm09" for the virus in 2010, after the conclusion of the pandemic.Swine flu was first recognized in the 1919 pandemic and still circulates as a seasonal flu virus. Swine flu is caused by the H1N1 virus strain, which started in pigs. The April 2...

Investigation of typhoid fever and their associated risk factors in children

Typhoid fever is a communicable disease transmitted by the bacteria Salmonella typhi, related to serotype paratyphi A, B and C. The disease is a significant health concern in most developing countries especially Cameroon.Objectives: The study aimed at assessing the risk factors associated to typhoid fever in children (0-18 years) attending the “Deo Gratias” hospital in Douala.Method: A hospital based cross sectional study from August to September 2018 was carried out in children aged 0-18...

Assessing the incidence of common bean in Cameroon

In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...

Culturing, Characterization And Identification Of Candidate Microorganisms In Cattle Ear, Responsible For Producing Volatile Constituents Attractive To The Brown Ear Tick

East Coast Fever is a disease of cattle which results in high animal mortality with corresponding economic losses to farmers and to the nation. The disease is caused by a protozoan agent whose vector is Rhipicephalus appendiculatus (Brown Ear Tick). The tick feeds dominantly inside the cattle ear. Studies have shown that the adults of R. appendiculatus exhibit „pull-push‟ effect that guides them to their preferred feeding site. This is linked to the presence of ear volatiles whi...

Effect Of Different Soil Fertility Amendments On The Nodulation And Yield Of Two Soybean Varieties

Soybean (Glycine max (L.) Merrill) is referred to as the golden crop of the future. There is a concern in Kenya on its production due to the fact that the country remains a net importer of this vital food to the tune of 100,000 tons annually yet the country has the potential to produce that capacity locally. The major impediments in local production are singled out as: Expensive farm inputs in form of fertilizers and use of inferior soybean varieties in terms of effective nodulation. Th...

Symbiotic Efficiency And Diversity Of Native Rhizobia Isolated From Climbing Beans (Phaseolus Vulgaris L.) In Embu And Tharaka Nithi Counties, Kenya

Kenya is the eighth highest producer of common beans (Phaseolus vulgaris L.) worldwide with a production of 529,265 tons annually. Climbing beans are highly productive, and can produce yields 2 to 3 times higher than bush beans and is therefore a promising option to increase bean yields in Kenya. However, climbing bean production is greatly affected by the decline in soil fertility, particularly low nitrogen levels in the soil. Replenishment of soil nitrogen using effective rhizobia in...
