ISOLATION AND IDENTIFICATION OF FUNGI FROM PACKAGED AND UNPACKAGED POWDERED MILK

CHAPTER ONE INTRODUCTION Food products are a rich nutrient source that can attract both bacterial and fungal colonizers. Pitt et al (2009). As such, the food product can be regarded as an ecological resource. Colonization with a number of food-borne microorganisms is beneficial with respect to nutritional value and prolonged storage of the food product, which is known as food fermentation in other case. After successful colonization of the product, ...

EFFECTS OF DIFFERENT LEVEL OF COW DUNG MANURE AND CHEMICAL FERTILIZER ON THE VEGETATIVE GROWTH OF SOME SELECTIVE COW PEA VARIETIES

ABSTRACT The low productivity of the cowpea (Vigna unguiculata L. Walp.) leafy vegetables in smallholder farms in Nigeria is partly attributed to moisture stress, declining soil fertility and poor leaf harvesting practices. To increase the productivity and utilization of these crops requires development of  suitable agronomic practices such as appropriate watering regimes, effective nutrient management, and best harvesting practices. Pot and field experiments were conducted at the University of Nairobi's ...

EVALUATION OF SOME COWPEA VARIETIES SUBJECTED TO ALTERNATIVE WETTING AND DRYING

ABSTRACT African leafy vegetables (ALVs) have a great potential in reducing the gap in nutritional status between low- and high-income households because of their nutrient densities and affordability. Cowpea is one of the major ALVs produced and consumed widely at the Coast and Western regions of Nigeria as a dual-purpose crop (grain and leaf). Although local cowpea accessions are preferred by farmers and consumers, there are still many challenges encountered. ...

ANTIFUNGAL ACTIVITY OF LOCALLY MADE SOAP ON DERMATOPHYTES ISOLATED FROM BARBING EQUIPMENT

ABSTRACT The comparative study on the effect of the locally made black soap and Dudu osun soap on dermatophytes isolated from barbing equipment using agar well diffusion method. The fungi isolated from the barbing equipment are Trichophyton rubrum (56.25%), Microsporum canis (28.13%), and Trichophyton mentagrophytes (15.63%).  The isolates were treated with Dudu Osun and Black soap, the result showed that Trichophyton rubrum was resistance to 100% concentration of dudu soap ...

MICROBIAL ASSESSMENT OF SMOKE CATFISH SOLD IN NGOMARI CONSTRAIN BUS STOP

CHAPTER ONE INTRODUCTION 1.1 Background to the Study  Fish is a very vital source of high quality protein and constitutes an important part of man’s diet; it is one of the most important animal foods available in the tropics (Eyo, 2001). Catfish, (Clarias gariepinus) accounts for about 80% of aquaculture production in Nigeria (FDF, 2003). However, fish is a perishable food material that deteriorates soon after harvest at high ambient ...

MICROBIAL EXAMINATION OF VEGETABLE SOUP

ABSTRACT This study was carried out on the microbial examination of vegetable soup. Five samples of vegetable (fluted pumpkin leaves) soup collected from different food vendors in (Campus 3) of the Institute of Management and Technology, Enugu were studied for bacteria spoilage. Different media were prepared and they include: MacConkey agar medium, nutrient agar medium, and blood agar medium.  After 24 hours of culturing on the media, observation of the ...

FUNGI ASSOCIATED WITH THE SPOILAGE OF COCOYAM

ABSTRACT Fungi associated with the spoilage of cocoyam (Colocasia esculenta) during storage at ambient temperature (28+20c) was investigated in this study. This was done by cutting the damaged portion of the cocoyam tubers and blend with diluents (water) to have even distribution of the microorganism and ensure ease of plating out. This done with the sample and inoculation was done from the 4th test tube on SDA medium and incubated ...

LEVELS OF POLYCYCLIC AROMATIC HYDROCARBONS IN FRESH WATER FISH DRIED UNDER DIFFERENT DRYING REGIME

ABSTRACT Preservation of fish by drying over different types of heat regimes have been known. However, there has not been a comprehensive comparison in terms of the possible contamination associated with these drying regimes. This work was set to evaluate the levels of PAHs that are likely to accumulate in the bodies of fresh water fishes dried under heat from charcoal, sun (sun drying), electric oven and polythene augmented drying ...
