ABSTRACT Micro-fungi are microorganisms that can withstand very low water concentrations. This enables them to grow on substrates where most other microorganisms do not grow. Fish is sun dried to reduce post-harvest deterioration and to provide a microbiologically stable product. In humid climatic conditions like those found in Gucha South due to high amount of rainfall throughout the year, the growth of micro-fungi on sun dried Rastrineobola argentea (Omena) is accelerated due to absorption ...
Abstract: The multiple roles of fungal entomopathogens in host plants’ growth promotion, pest and pathogen management have drawn huge attention for investigation. Endophytic species are known to influence various activities of their associated host plants, and the endophyte-colonized plants have been demonstrated to gain huge benefits from these symbiotic associations. The potential application of fungal endophytes as alternative to inorganic fertilizers for crop improvement has often been...
Abstract: The spider mites Tetranychus urticae Koch and Tetranychus evansi Baker and Pritchard are important pests of horticultural crops. They are infected by entomopathogenic fungi naturally or experimentally. Fungal pathogens known to cause high infection in spider mite populations belong to the order Entomophthorales and include Neozygites spp. Studies are being carried out to develop some of these fungi as mycoacaricides, as standalone control measures in an inundative strategy to repla...
ABSTRACT This study involved isolation of compounds from the plant Monanthotaxis littoralis, screening and evaluating the activity of the compounds against mycotoxigenic fungi isolated from maize collected from LVB and structure elucidation of the bioactive compounds. The non volatile secondary metabolites were extracted from the plant using methanol. The methanol extract was suspended in water and extracted with ethyl acetate. Hydro-distillation was used in the extraction of essential oils....
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 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 ...
ABSTRACT Yogurt sold at different manufacturer, in Ilorin Kwara State was taken to the laboratory and examined, different bacteria and fungi were found in all the yoghurt tested using conventional methods. The implications of these micro organisms were discussed.
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: In the past few decades, the control of pests and diseases of cultivated plants using natural and biological measures has drawn increasing attention in the quest to reduce the level of dependence on chemical products for agricultural production. The use of living organisms, predators, parasitoids, and microorganisms, such as viruses, bacteria, and fungi, has proven to be a viable and sustainable pest management technique. Among the aforementioned, fungi, most importantly the insect...

ABSTRACT The effectiveness of cotton seed dextrose agar, groundnut seed dextrose agar and kernel dextrose agar in culturing fungi was studied by culturing fungi from yam rot (Dioscorea rotundata). The research demonstrated the choice of the isolated fungi to various media, and revealed that some of the isolated fungi showed the same occurrence in different media. Aspergillus flavus showed preference for kernel dextrose and groundnut seed dextrose agar than Sabouraud dextrose agar and cotton s...
Abstract: The pineapple fruit is a component of the traditional medicine, it is also known with excellent quality, special flavor, and nutritional richness, is favored by consumers worldwide. The pineapple fruit juice contributes to healthy living, because it is good source of vitamins, phenols, organic acids and carbohydrate. The aim of this research was to conduct study on antimicrobial and antioxidant activities of endophytic fungi from pineapple fruit using isolation method. The experime...
In Menoua Division, common bean (Phaseolus vulgaris L.) is amongst the legumes which are greatly cultivated with farmers growing different cultivar types. Upon harvest, these cultivars are stored to be used as food over the storage period or for sale. Unfortunately, appropriate facilities for storing the cultivars after harvest are not available hence predisposing the grains to fungi infection. The knowledge of cultivars resistant to damage by storage fungi would therefore have a consider...
In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...
ABSTRACT Various plant diseases (Fusarium ear rots, bean anthracnose and damping off of seedlings) caused by phytopathogenic agents are known to cause considerable crop losses to agricultural yield all over the world. The use of antagonistic microorganisms in controlling maize and bean pathogens is an area of great potential in order to increase yield, thereof mitigate food insecurity. The aim of this study was to characterize and screen selected tropical fungi and bacteria for antimicrobial ...
