Explore Project Topics on: isolation of fungi associted with necrotic spot on jatropha curcas and psidium guajava

ABSTRACT             Guava (Psidium guajava L) is native to South America and exists as both wild and cultivated. Guava has been used as a source of food and raw materials for pharmaceuticals. The aim of this study was to determine bioactivity of methanol and water extracts from apple guava against selected pathogenic bacteria. Study samples... Continue Reading

ABSTRACT Growing of Jatropha curcas has been received with mixed feelings in Kenya. The plant has tremendous potential to be Africa's most excellent bio-fuel feedstock. However, there have been concerns that the plant is not commercially viable and that it negatively affects food production and security. The lack of factual information coupled... Continue Reading

ISOLATION, IDENTIFICATION AND CHARATERIZATION OF FUNGI ASSOCIATED WITH THE SPOILAGE OF CORN ABSTRACT Fungi spoilage organisms are silently invading acidifying, fermenting, discoloring, and disintegrating microbes that render corn (zea mays) unpalatable and unsafe. Fungi spoilage is caused by two factors, (biotic) living which includes insects,... Continue Reading

ABSTRACT The present study is to isolate fungi from rhizosphere of Moringa oleifera and screen them for the production of some very important enzymes such as amylase and protease. Twenty fungi were isolated from the soil sample from five different farms using pour plate method. The isolates were then identified based on their colonial morphology... Continue Reading

ABSTRACT Human systemic fungal infections have increased in the past decade due to the dramatic increase in immunocompromised patients hence the emergence of resistant fungal strains. It is therefore necessary to discover new antifungal compounds with novel mode of action. This study was aimed at isolating and characterizing antifungal agents from... Continue Reading

Pepper are subjected to many problems such as weeds and diseases like tobacco mosaic virus, damping off, blossom end rot, spotted wilt phytophthora root rot, cucumber virus, bacterial spot, Alternaria leaf spot and of cause Cercospora leaf spot. Therefore this study was conducted to determine the effect of rice husk extract on leaf spot disease of... Continue Reading

ABSTRACT: The interest in using Jatropha curcas L. (JCL) as a feedstock for the production of bio-diesel is rapidly growing. The properties of the crop and its oil have persuaded investors and policy makers to consider JCL as a substitute for fossil fuels to reduce greenhouse gas emissions. In this report, we gave an overview of the currently... Continue Reading

CHAPTER ONE 1.0  GENERAL INTRODUCTION 1.1 Introduction Grains constitute the most important staple food for the growing population in most parts of the world and are usually stored to provide food reserve and seeds for planting (Niber, 1994). Maize is a very important crop of the world after wheat and rice (Purseglove, 1992). Maize (Zea mays)... Continue Reading

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...

ABSTRACT Fish is highly nutritious with high protein content. However, it is a suitable medium for growth of microorganisms, if poorly processed (Oparaku and Mgbenka, 2012). The growth of microorganisms and other non-microbial activities such as lipid oxidation contribute to the deterioration of fish products (Martin, 2010). An increase in the... Continue Reading
