ABSTRACT Aflasafe KE01 is a biological control product comprising of four atoxigenic strains of Aspergillus flavus which are native in Kenya. This study determined the efficacy of Aflasafe KE01 on the population of aflatoxin producing fungi and aflatoxin contamination of maize in alternate seasons. Field efficacy trials were carried out in aflatoxin hot spots in Kathiani and Wote sub Counties in lower Eastern Kenya. Twenty four maize fields were selected at random in each Sub County where 12 ...
ABSTRACT The Petroleum Industry has a huge potential for the pollution of the environment at every stage of its operation, hence the need to constantly fashion out new strategies for maintaining the sanctity of our environment. Fungi associated with diseased Irvingia gabonensis (Baill) seeds found in the open markets were suspected to possess the ability to degrade the hydrocarbon substances contained in these seeds. These fungi were isolated bimonthly from the diseased seeds of I.gabonensis...
ABSTRACT Fungi are eukaryotic microorganisms that have simple multicellular or unicellular cell structures. They are distributed in terrestrial soils, forests, aquatic habitats and in extreme environments with high ambient salts, temperature, pH and pressure. Fungi from extreme environments are potential sources of novel biocatalysts for example antimicrobial agents that can help solve the rising cases of drug resistance. However, the diversity of fungi recovered and described from less studi...
ABSTRACT The socioeconomic burden of pollen and fungi spores allergy are very high in terms of hospitalization, treatment, lethargy, poor concentration and behavioral changes which impact negatively on adults and children. The study of atmospheric pollen and fungal spores in the six geopolitical zones of Nigeria was carried out from June 2011 to May 2012. The aims of the study are to determine the seasonal prevalence of atmospheric pollen and fungal spores, examine the impacts of weather par...
ABSTRACT The process of re-establishing the natural level of arbuscular mycorrhizae (AM) fungi richness can represent a valid alternative to conventional phosphate based fertilization practices, with a view to sustainable agriculture. The main strategy that can be adopted to achieve this goal is the direct re-introduction of AM fungi inoculum into a target soil. AM fungi have a high affinity for phosphorus, an essential macronutrient that participates in the skeleton of the nucleic acids DNA ...
ABSTRACT Viruses and fungi are the major threat to sweet potato production because they reduce yield by up to 90% thereby threatening food security. A study was carried out to identify pathogenic viruses and fungi affecting sweet potato and to determine their distribution across varieties and sites in Gweru. A total of 28 samples belonging to five different sweet potato varieties were collected from nine sites in Gweru. Plants were screened for viruses using two methods namely direct observat...
ABSTRACT Marine-derived endophytic fungi isolated from mangrove plants are an important and novel resource of natural bioactive compounds with their potential applications in medicine, agriculture and food industry. There are many instances that seem to suggest that, some of the novel metabolites previously isolated from certain species of marine plants and invertebrates are actually metabolites of marine-derived endophytic fungi. In this project, chemical screening of mangrove plantsConocarp...
ABSTRACT Over the years, natural products have played a major role in the search for novel drugs or drug candidates. Secondary metabolites from nature especially those of fungal origin exhibit unique biological activities and research continue to meet the keen interests which have potential pharmaceutical value. Fungi constitute an important source of secondary metabolites such as penicillin. The present study analyzed the biological activities of a variety of compound mixtures from wood deca...
ABSTRACT This study evaluated the protein fatty acid and mineral changes in sweet potato root iheal inoculated with two selected fungi by solid state fermentation procedure. The total protein content was raised from 4.95% to 11.83% and 6.69% within 48 hrs for Aspergillus oryzae and Aspergillus niger respectively. The total lipid dropped from 1.93% in thè control to 1.36 and 4.19% for A. niger and A. oryzae respectively. The fatty acids 0 6 : 0 and 0 8 :2 were preponderant over other fatty ac...
ABSTRACT The study was carried out to assess the influence of Colletotrichum dematium one of the major causes of pepper diseases on the declining yield of pepper in the Ajumako Enyan Essiam district of the Central Region and to find the extent of transmission through different inoculation methods. Three fruit types (riped, unriped and dropped) were collected from six farms across four locations (Akuamase, Nkodwo, Esikado and Mando) and another sample which was made up of only riped fruits was...
ABSTRACT Six species of known toxigenic and zoopathogenic fungi were isolated from Nigerian poultry feeds. These include Aspergillus flavus Link: Fr. (IMI 280819), A. fumiga tus Fres. (1M1 280822), ~ niger v. Tieghem (IM1 280823), A. oryzae (Ahlburg) Cohn (IM1 280831), Rhizopus arrhizus Fischer (1M1 280827) and Rhizomucor pusillus Lindt Schipper (1MI 280824). Growth-temperature range for the. fungi was between 15° and 45°C. Aspergillus fu~igatus and Rhizomucor pusillus are t he r mot o Le ...
Medicinal plants have provided a source of inspiration for novel drugs compounds since plant derived medicines have made large contributions to human health. The traditional healers make use of water primarily as solvent but extracts of these plants were certainly much better and powerful. This may be due to the better solubility of the active components in organic solvents (Umadevi, 2011). The phytochemical component of the ethanolic extracts of Basella alba leaf revealed the presence of tan...
ABSTRACT Hymenula cerealis, Neottiosporella radiata, Sphaerosporium lignatile, and Monilochaetes infuscans were isolated from soil of Botanical Garden, Obafemi Awolowo University, Ile-Ife. The soil sample was serially diluted and isolation was done using pour plate method. The organisms were then screened for cellulase production using carboxymethyl cellulase and Congo red. The screening result showed that Hymenula cerealis, Neottiosporella radiata, and Sphaerosporium lignatile are capable ...
ABSTRACTThe 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 and microscopic features in wet mount and Lactophenol Cotton Blue staining. All the isolates were screened for amylase and protease production by star...
ABSTRACTThis study was conducted to examine the fungi present in spoilt onion bulb. Five different sample of spoilt onion bulb were blended together and suspended in sterilized distilled water which was used to inoculate Sabouraud dextrose agar (SDA). Four different fungi were isolated from the sample and the morphological characteristics shows that the isolate belong to the following genera: Alternaria sp., Aspergillius sp., Penicillium sp., and Rhizopus sp. These fungi may have been respons...
