Safety And Nutritional Quality Of Pastoral Traditional Fermented Camel Milk (SUUSA)

ABSTRACT Suusa is spontaneously fermented raw camel milk prepared by pastoral women and informally marketed in Kenya. Processors, traders and consumers of suusa rely on organoleptic testing for quality and safety along the suusa value chain. Handling practices in raw milk and suusa products potentially exposes the product to microbial contamination which is associated with reduced shelf life and risk of infections to consumers with milk borne and zoonotic diseases such as brucellosis and tub...

Combined Antibacterial And Antifungal Activities Of Eucalyptus Citriodora And Syzygium Aromaticum Essential Oils

ABSTRACT The emergence of multi-drug resistant strains is a formidable threat to the fight against skin diseases and hence effective alternative regimes must be sought. Although many studies have been done on antimicrobial activities of Syzygium aromaticum and Eucalyptus citriodora oils, no information is available on their antimicrobial interaction and hence the purpose of this study. Bioactivity testing of Syzygium aromaticum and Eucalyptus citriodora oils was done using disc diffusion tec...

Facies Model Building of Integrated Multiscale Data In Dn-Field, Onshore, Niger Delta, Nigeria

Abstract This study employs 3D Post-Stack Time-Migrated seismic data from the DN-Field, within the Coastal Swamp depobelt of the Niger Delta in predicting lithofacies and fluvial facies of OVK-1 sand bodies in the Agbada Formation, as a tool to identify new drillable prospects. A lithofacies model for OVK-1 reservoir sand body was generated after upscaling using Most Of, as the averaging method. Calibrated by fluvio-facies at the well locations, channel sands were identified in OVK1 reservoi...

Phytochemical Screening and Microbial Inhibitory Activities of Ficus Capensi

ABSTRACT Ficus plant components have application in traditional medicine because of the myriad uses they have been subjected to. The ease of application is based on the secondary metabolites this plant contains. The challenges faced by modern medicine especially in the complete cure of microbially-associated diseases through abrupt and unpredictable genetic mutations in the presence of conventional drugs informed the investigation of the microbial inhibitory activities of the stem, root and l...

Aspects of Source Rock Evaluation and Diagenetic History of the Akinbo' Shale Eastern Dahomey Basin, Southwestern Nigeria

Abstract The Akinbo Formation comprises a sequence of mostly dark, pale-greenish grey, laminated shale, slightly glauconitic shale, sandy shale with subordinate claystone lenses. Selected subsurface samples of the shaly facies as penetrated by Akinside 1582 well in eastern Dahomey basin, were investigated by sedimentological, mineralogical and geochemical parameters to ascertain the hydrocarbon potential and deduce the influence of variations of clay mineral indicators on the prospect. Values...

Ecological Utilization Of The Weed – Tithonia Diversifolia And Sustainability Of The Paper Industry In Nigeria

Abstract Tithonia diversifolia is found growing abundantly within the forest zone of Nigeria. The evaluation of the pulp and paper making properties of T. diverisifolia showed average fibre length, width, wall thickness and lumen of 827.66  186.40m, 20.29  3.92 m, 3.96  0.28 m and 12.16  3.96 m respectively.  This short fibre length and small wall thickness of T. diversifolia made it unsuitable for making strong papers.  However, it is good material for mak...

Geophysical Investigation of Foundation Condition of A Site in Ikere- Ekiti, Ekiti State, South-Western Nigeria

Abstract: A geophysical investigation has been performed using Vertical Electrical Sounding (VES) at a site behind Sammy Guest House in Ikere-Ekiti, Ekiti-State to examine the geophysical parameters that can be used to evaluate the structural competence of the shallow section of the subsurface for construction purposes and building development. The schlumberger configuration was used for the data acquisition. The half- currents electrode (AB/2) was used and the quantitative interpretation of...

Evaluation Of Extruded Snacks From Blends Of Acha (Digitaria Exilis) And Cowpea ( Vigna Unguiculata) Flours

Abstract The production of acha and cowpea are the complementary food and are produced in large quantities in Nigeria, which are the major sources of protein and carbohydrate respectively. The study was proposed on developed high protein energy complementary foods from the blends of cowpea and acha using extrusion cooking. Cultivars of cowpea (IT90K-277-2) and acha (cream colour) were selected and milled into flours. Using the response surface methodology, the blends of acha and cowpea flours...

Degradation of Polyamide-6 By Microbial Isolates from Solid Waste Dumpsites in Lagos State, Nigeria

ABSTRACT Polyamide-6 (also known as nylon-6) is one of the biodegradation-resistant synthetic polymers used in the manufacturing of commodity plastic materials. The environmental effects of the persistence of this material in landfill and on surface water bodies pose global problems that endanger public health. Knowledge of the microbial distribution and pattern of their interaction with these plastics will provide the biological resources and scientific basis for the development of sustaina...

Molecular Analysis Of Mechanisms And Identification Of Factors Of Pyrethroid Resistance In Anopheles Gambiae Sensu Lato In Southwestern Nigeria And Southern Benin Republic

ABSTRACT The development of resistance to insecticides by Anopheles mosquitoes continues to threaten the success of malaria control programmes in West Africa. Local data on mechanisms and factors causing resistance in the region are scanty. This study was designed to investigate the environmental factors and mechanisms implicated in resistance to pyrethroids by Anopheles gambiae in southwestern Nigeria and southern Benin Republic.  Larvae of Anopheles mosquito were collected in 2007 from 19...

Selection, Product Characteristics And Metabolite Spectrum Of A Common Starter Culture For Fufu And Usi Production

ABSTRACT Fermented cassava products like fufu and usi (edible starch) are important staple foods in many African homes. Natural fermentation time is usually long resulting in slower acidification process and inconsistent nutritional composition of products which could be overcome with the use of starter culture. However, most available starter cultures are used for single food fermentation and are uneconomical. This necessitates the development of a starter culture for multiple related food ...

Petroleum Exploitation or Human Exploitation? An Overview of Niger Delta Oil Producing Communities in Nigeria

Abstract This paper examined the impact of petroleum exploitation on the environment of the Niger Delta oil producing communities in Nigeria. This is in furtherance of the understanding that human beings are at the centre of concerns for sustainable development. The paper observed that there was need for the adoption of measures that would provide a reasonable degree of protection of ecological and human environment from the activities of the oil industry in Nigeria.

PREVALENCE AND INTENSITY OF NEMATODE PARASITES OF Poecilia reticulata PETERS (1859) IN FOUR WASTEWATER DRAINS OF LAGOS STATE, NIGERIA

ABSTRACT  Poecilia reticulata (guppy) a common ornamental tropical fish is found in many wastewater drains in Nigeria. Guppies feed on copepods which are intermediate hosts of some nematode parasites of culturable fish species. The restriction on the importation of ornamental fishes into Nigeria has enhanced the demand for local species, usually sourced from the wild. There is dearth of information on the parasites of ornamental fishes in Nigeria. This study was aimed at determining prevale...

Evaluation Of Infestation And Damage By The Larger Grain Borer (Prostephanus Truncatus) (Horn) (Coleoptera: Bostrichidae) On Selected Food Grain Crops

ABSTRACT The study evaluated the ability of the larger grain borer (LGB), Prostephanus truncatus (Horn) to infest and damage two varieties of sorghum (Sorghum bicolour), Sesame (Sesamum indicum) Cowpea (Vigna unguiculata) and maize (Zea mays). 100 g each of the grain products were infested with 5 pairs (5 males and 5 females) of 1-10 day old LGB for 90 days. At 90 days post-infestation of the crops, the insects and grain dust generated by the feeding activities of the insects were sieved out...
