QUALITY ASSURANCE AND QUALITY CONTROL FOR WATER AND FOOD ANALYSIS

Great attention has been paid to food and water quality for centuries. The requirements have been changed according to the development of human knowledge in the field of nutrition, chemistry, microbiology, and analysis. It is necessary first to point out that the term food and water quality is a complex one that includes many indicators. For food and water to be classified as good, it has to fulfill the requirements, especially from the nutritional, sensory, hygienic-toxicological, and techn...

Biofilm Formation and Antibiotic Resistance of Uropathogens Isolated from Patients attending a Teaching Hospital in Anambra State Nigeria

The main aim of this research was to characterize the enterobacterial uropathogens with respect to drug resistance in Awka, south-eastern Nigeria. The following enterobacterial uropathogens isolated from patients attending Chukwuemeka Odumegwu Ojukwu University Teaching Hospital, Awka were studied: E.coli (58), Salmonella spp. (15), K. pneumoniae (14), Citrobacter freundii (10) and Enterobacter aerogenes(3). Their antibiotic susceptibility patterns against major classes of antibiotics were e...

Reverse Osmosis Technology, its Applications and Nano-Enabled Membrane

Reverse Osmosis (RO) is the finest of all membrane filtration system, it is a membrane based technology to purify water by separating the dissolved solids from feed stream resulting in permeate and reject stream for a wide range of applications in domestic as well as industrial applications. The objective of this paper is to review the concept of reverse osmosis and the current developments in the RO membrane materials which are the key determinants in the process. This review paper also ...

Phytochemical Screening and Antibacterial Activity of Spondias mombin Leaves

Phytochemical investigation was carried out on the crude ethanol extracts of the leaves of Spondias  mombin. The antibacterial activity of the ethanolic and the Chloroform leaf extract was tested  against four bacteria; Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi using disc diffusion method. The results indicated that both extracts showed inhibitory activity against clinical isolates of the gram negative bacteria Staphylococcus aureus, P. aerugi...

The  physicochemical  parameters  and  levels  of  selected  heavy  metals  (Cd,  Cr,  Mn,  Zn  and  Pb)  in soil  around  Dana  Steel  Rolling  Limted  Katsina  were  investigated  in  this  research.  The  sample  area was  divided  into  four  units;  East,  West,  North  and  South  and  label  as  A,  B,  C  and  D  respectively using  stratified  random  sampling  method.    The  soil  was  digested  using  H2SO4,  HClO4 and  H...

ANTIBIOTIC SENSITIVITY TESTING ON EGGS FROM LAYERS TREATED WITH ANTIBIOTIC

ANTIBIOTIC SENSITIVITY TESTING ON EGGS FROM LAYERS TREATED WITH ANTIBIOTIC   A RESEARCH PROJECT   ABSTRACT Antibiotic sensitivity testing is the susceptibility of bacteria to antibiotics, it is carried out to determine which antibiotic will be most successful in treating a bacterial infections. The total mean colony count of the bacterial isolates in the two set of egg sample  carried out showed the mean total bacterial count as 0.33x102 – 3.6 x 102 cfu/ml. While the antibiot...

Preliminary structural evaluation of an X-Field Onshore in Niger Delta using 3D seismic data A structural evaluation of a post stack time migrated (PSTM) 3D seismic data over an X–Field in the eastern Niger Delta has been attempted. The objective of the study is to structurally evaluate the field with a view to identifying structural features such as faults, map geologic horizons and analyze reflection characteristics that might be a good lead to probable hydrocarbon accumulations. Results ...

PRODUCTION OF INSECTICIDAL COMPOUNDS USING BACTERIA AND FUNGI

Pest and diseases have a serious effect on food production. Global crop yields are reduced by 20 to 40% annually due to impact of pests and diseases.Indiscriminate use of insecticides to combat insect challenges, have increased the selection pressure leading to resistance in insects. In such a situation, alternate options of insect control are advocated. The use of microbial insecticidal compounds offer adequate levels of insect control and pose fewer hazards.Microbial insecticidal compou...
