HYDROCARBON DEGRADING POTENTIALS OF BACTERIAL ISOLATES FROM PETROLEUM REFINERY SLUDGE.
ODJADJARE, E. E. O. AND INEGBONOSUN, E. A.
ABSTRACT
Petroleum contain fractions that are potentially toxic, carcinogenic and or mutagenic. Thus the intrinsic biodegradability of petroleum hydrocarbon and distribution in the environment of competent catabolic microorganisms are critical to the implementation of bioremediation strategies for the clean-up of petroleum polluted environments towards ecosystem and public health preservation. In the present study, the petroleum degrading potentials of bacteria species isolated from petroleum refinery sludge was
evaluated. The bacterial species were isolated and identified…

ADEBOLA, M. O., BELLO, T. S., YUSUF, H. AND EGUBAGI, J. M.
ABSTRACT
The use of plant extracts in controlling plant diseases has witnessed appreciable success; such was exploited in this study when efficacy of extracts from Azadirachta indica, Calotropis procera and Anacardium occidentale, each at different concentrations; 30 mg ml-1, 60 mg ml-1, 90 mg ml-1 and 0 mg ml-1 (Control), were examined in vitro to control Botrytis cinerea that causes damping off disease of Citrullus lanatus var. ‘lanatus’. Result showed that the mean inhibition in colony diameter at 90 mg ml-1
ranged from 0.26-2.26 (A. indica), 0.43-3.30 (C. procera) and 0.13-2.50 (A. occidentale) compared respectively to 0.5-4.36, 0.57-4.33 and 0.43-4.10 in their 0 mg ml-1 concentration. The 90 mg ml-1 concentration that has the least fungaly..

MICROBIAL LOAD AND PHYSICO-CHEMICAL PROPERTIES OF SOIL IN NATIONAL CEREAL RESEARCH INSTITUTE RICE FIELD, BADEGGI,
NIGERIA.
ADEBOLA, M.O. AREMU, M. B. AND OKAFOR, H.
ABSTRACT
This study was carried out to evaluate the microbial load and pyhsico-chemical properties of the soil in National Cereal Research Institute rice field, Badeggi, Nigeria. The soil samples collected from fadama, hydromorphic and uncultivated field of NCRI were serially diluted and plated on Potato Dextrose Agar and Nutrient Agar. The incubation was done at 27oC and the associated bacteria and fungi were isolated and enumerated. The physico-chemical properties of the soil were also done. A total of seven (7) bacteria; Echericha coli, Staphylococcus aureus, Enterobacter aerogenes..

THE COMBINATORIAL GENERATION AND THE MATRIX ELIMINATION MODEL FOR THE LONG-RUN DIAGNOSTIC STABILITY OF AN AUTOREGRESSIVE DISTRIBUTED LAG (ARDL) MODEL.
EGUASA, O., MBEGBU, J. I.AND OBADONI, J.
ABSTRACT
This study examines the long – run stability of an Autoregressive Distributed Lag (ARDL) model with intercept and no constant trend, using quarterly data from CBN annual statistical bulletin that span from 1999Q1 to 2011Q2 and 2000Q1 to 2012Q4. The parameters of the long – run stability of ARDL model are not all statistically significant in their respective p – values and as such cannot be totally relied upon for statistical estimation. Then, we proposed a matrix elimination model which is motivated by the p – values of the…

PHYTOCHEMICAL ANALYSIS OF Gongronema latifolium (“Utazi”) LEAF AND
ITS BIOACTIVITY ON MICROBIAL ISOLATES FROM AFRICAN SORGHUM BEER (Burukutu)
OMOGBAI, B. A., EIGHEMENRIO, O. S., OBAZENU, E. I.,IDUORIYEKEMWEN, A. S. AND UBAKA, L. N.
ABSTRACT
Forty-five (45) samples of prepared burukutu from Kaduna were microbiologically examined for microbial isolates using standard methods. Leaf extract of Gongronema latifolium was obtained using ethanol, hot and cold water as solvents. Phytochemical analysis of the plant was carried out using standard chemical methods. Antimicrobial properties of the extracts were evaluated using agar well diffusion method. The mean bacterial count of burukutu samples ranged from 1.2 ± 0.10 × 106 to 8.3 ± 0.30 ×106 cfu/ml in Kachia, 1.6 ± 0.32 × 106 to 5.1 ± 0.44 × 106 cfu/ml (Kajuru) and 1.4 ± 0.21 × 106 to 7.2 ± 0.40 × 106 cfu/ml in Kudan. The mean fungal count ranged from 1.47 ± 0.31 × 106 to 3.87 ± 0.35 × 106 cfu/ml in Kachia, 1.27 ± 0.12 × 106 to 3.37 ± 0.35 × 106 cfu/ml (Kajuru) and 1.50 ± 0.27 × 106 to 4.00 ± 0.30 × 106 cfu/ml in Kudan. Seven bacterial……

EXTENSION DELIVERY: THE BANE OF RUBBER PRODUCTION IN EDO SOUTH AGRO-ECOLOGICAL ZONE OF NIGERIA.
ALAKPA, S. O. E.
ABSTRACT
Rubber yield has been on the decline and below expectation due to the gap created by lack of extension services delivery. This study examined the awareness level of Agricultural Extension service delivery in rubber production in Edo South ecological zone of Nigeria. The main objective was to determine the respondents’ awareness level of improved technologies and adoption rate. A sample size of 150 farmers was used from the list of rubber farmers obtained from Edo State Ministry of Agriculture and Rural Development and Tree Crop Unit of the Federal Ministry of Agriculture. Valid questionnaire used for the study were 137. A multi-stage sampling technique was adopted for the study. Data collected were
analyzed using…..

OMOGBAI, B. A., OBAZENU, E. I., IDUORIYEKEMWEN, A. S., UBAKA, L. N. AND IMONI, A. A.
ABSTRACT
An increasing interest for global food shortages for the world’s expanding population necessitated the use of agro-waste as food sources or supplement for animal feeds. Candida tropicalis MYA- 3404 was isolated from pineapple fruit waste and identified by both phenotypic and molecular methods. Proximate analysis of three agro-wastes: melon, groundnut and walnut shell was carried out by standard chemical analytical methods. The protein content ranged between 3.73 to 12.14 % with groundnut shell having the highest.
The shells contained 61.26 to 65.12 % carbohydrate. The moisture, fibre, ash and lipids were….

ANTIBIOTICS SUSCEPTIBILITY PROFILE OF BACTERIA ISOLATED FROM FISH PONDS IN BENIN CITY.
LUCKY OMOROGIUWA
ABSTRACT
Fish farming is a recognized means of livelihood in Nigeria; however, the intensive use of antibiotics to prevent infection and increase fish yield calls for concern. This practice may lead to the growth of antibiotics resistant bacteria which contains resistant genes that can be transferred to human pathogens, causing treatment‐ resistant illness. This study investigated the antibiotics susceptibility profile of bacteria isolated from five fish ponds in Benin City using standard microbiological procedures. Isolates were identified using morphological characteristics and conventional…

MAXIMUM LIKELIHOOD PARAMETER BASED ESTIMATION FOR IN-DEPTH PROGNOSIS INVESTIGATION OF STOCHASTIC ELECTRIC FIELD STRENGTH DATA.
JOSEPH ISABONA
ABSTRACT
This work centers on parametised investigation of the field strength fading characteristics of microcellular wireless LTE channels operating in typical urban terrains. Due to the blockades between the transmitting NodeBs and the mobile station receiver, the fading characteristics of LTE channel are highly stochastic with respect to time or transmitting distance and possesses their own distinctive property. To robustly investigate the field strength fading characteristics, detail drive test measurement has been conducted in five different site locations in waterline area of Port Harcourt City….
