BACTERIOLOGICAL QUALITY OF PROCESSED, PACKAGED AND STORED CONOPHOR (Tetracarpidium conophorum) NUTS

Emeka Nwabunnia*, Ngozi E. Ezeimo

The present study dealt with the formulation and bacteriological quality assessment of two novel methods for processing of conophor (Tetracarpidium conophorum) nuts as food. Cooked-and-roasted (CR) and steeped-and-roasted (SR) conophor nuts stored for 28 days in air-tight transparent glass bottles at room temperature (30±2°C) were analyzed for total aerobic heterotrophic bacterial (TAHB) and total...

EFFECT OF AERATION ON FERMENTATION OF Mucuna jaspadae USING Bacillus subtilis AS THE STARTER CULTURE

Gabriel-Ajobiewe R.A.O.*, Akinbobola A.

Various efforts are currently being directed at exploiting the vast majority of unconventional protein sources in order to ameliorate the problem of protein deficiency associated with developing communities and of such is the production of Mucuna beans condiments through fermentation process. The effect of aeration on the fermentation of Mucuna jaspadae beans using Bacillus subtilis at three aerat...

MORPHOGENESIS OF ORAL AND GENITOURINARY TRACT ISOLATES OF Candida albicans STRAINS AS INFLUENCED BY DIFFERENT GROWTH CONDITIONS

Uzoechi A. U*, Vwaezuoke J,C,, Nwachukwu I. O, Ahuocha Pauline, Nwachukwu M.J

Growth pattern and mycelia formation of two strains O (Oral isolate) and G (genitourinary tract isolate) of Candida albicans in horse-serum, MSB and RPMI 1640 media indicates that the first medium promotes filamentation in both strains while MSB initiates medium mycelium formation for O strain and RPMI stimulates the yeast growth and low filamentation. However, RPMI promotes moderate filamentation...

ANTIMICROBIAL EFFECT OF Nicotiana tabacum (TOBACCO) LEAF EXTRACT ON Staphylococcus aureus and Escherichia coli

Korondu S. I.*, Okorondu M.M.O., Oranusi,S. C.

The present study evaluates the phytochemical composition of ethanolic extract and antimicrobial property of ethanolic and aqueous extracts of Nicotiana tabacum. The antimicrobial effects of Nicotiana tabacum (tobacco) leaf extract on microbial isolates (Staphylococcus aureus and Escherichia coli) was evaluated using using agar well diffusion method. Also, the Phytochemical screening of the plant ...

ISOLATION AND GROWTH CHARACTERISTICS OF Bacillus sp. SD12 IN MEDIUM CONTAINING MIXTURES OF 4-CHLOROPHENOL AND ZINC

Nwanyanwu, C. E*, Opurum, C.C., Eze, C.C

A bacterial strain tolerance to 4-Chlorophenol and Zinc was isolated from sediment of Okrika River that receives effluent from petroleum refinery plant. Out of fifteen (15) bacterial strains isolated, only one of the isolates identified as Bacillus sp. SD12 with highest adhesion to soil (47.4 %) was found to be tolerant to high concentrations of both 4-CP (400 ug/ml) and Zn (200 ug/ml), and hence ...

BIOCONVERSION OF ORANGE PEELS INTO A NUTRITIONALLY ENRICHED SUBSTRATE BY Trichosporonoides oedocephalis, Penicillium italicum AND Aspergillus flavus

Oladipo O. Olaniyi*, Emmanuel O. Bankefa, Olukayode A. Ibitoye

This study was conducted to investigate the effects of fungal based fermentation on the nutritional composition of orange peels. The effect of solid state fermentation (SSF) on the nutrients and anti-nutritional factors (ANF) of orange peels was achieved by Trichosporonoides oedocephalis, Penicillium italicum and Aspergillus flavus with two inocula concentrations (103 and 105 spores/ml). The prote...

THE DOMINANCE OF THE GENERA Myroides AND Proteus WITHIN HYDROCARBON UTILIZING POPULATIONS IN SOME CRUDE OIL-IMPACTED SITES

Chioma Blaise Chikere*, Gideon Chijioke Okpokwasili

Hydrocarbon utilizing bacteria in environmental samples collected from crude oil impacted sites at Eleme, Rivers State, and five water samples from effluent discharge points at five different flow-stations in Delta State, all in the Niger Delta were isolated using Bushnell Haas agar. Bacterial genera tentatively characterized were Acinetobacter, Alcaligenes, Bacillus, Edwardsiella, Enterobacter, F...

THE SEROLOGICAL STATUS FOR NEWCASTLE DISEASE IN LOCAL CHICKENS OF LIVE BIRD MARKETS AND HOUSE HOLDS IN NSUKKA, ENUGU STATE, NIGERIA

Eze, lfeanyi Amos, Ike, Anthony Chibuogwu*

Newcastle disease (ND) is the most important viral disease of poultry in the world and a major constraint against both Industrial and village poultry production in Africa and Asia. A serological study was conducted to estimate the level of circulating antibodies against ND in unvaccinated local chickens, raised under traditional management system in Nsukka, Enugu State, Nigeria. Haemagglutination ...
