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...
INTRODUCTION Jock itch gets its name because it is common in people who sweat a lot, majorly the athletes. It is also more likely to occur in people who are overweight. Although often uncomfortable and bothersome, jock itch usually is not serious. Jock itch (tinea cruris) is a fungal infection that affects the skin of the genitals, inner thighs and buttocks. Jock itch causes an itchy, red, often ring-shaped rash in these warm, moist areas of the body. groin area clean and dry and applying t...
Abstract: Globally, orange is one of the major fruit crops contributing to nutrition and monetary income. False codling moth (FCM), Thaumatotibia leucotreta, is one of the major constraints of orange production. Before this study, little was known regarding the bioecology of FCM in orange and vegetables in Kenya and Tanzania and the potential use of dry conidia of entomopathogenic fungi for control of T. leucotreta moths has not been tested. There is also no IPM strategy available for FCM in...
Abstract: Banana is an edible fruit and herbaceous flowering plant belonging to genus musa and family musaceae.Banana is a source of natural antioxidants and has good antimicrobial potential. Banana Peel is nutritional and rich in phytochemical compounds than its pulp. Characterization of the antioxidant and antimicrobial activities of endophytic fungi extracted from banana peel and pulp is the main purpose of this study.The banana fruit sample was collected from dingete locality Gemechis di...
Abstract: Pectinases are the group of enzymes that degrade pectin. This study was conducted with the aim of isolation of efficient pectinase producing pectinoloytic fungi from the decaying vegetable and fruit soil containing decomposing mango peels using extracted mango peels pectin as a growth substrate under submerged fermentation, determining optimum pectinase production conditions and characterizing of ammonium sulphate precipitated pectinase activity with regards to some physicochemical...
ABSTRACT Microorganismsare essential players in the very existence of all living thing. They play avery important part in the production and biodegradation of organic foodsubstances in which Manihot esculentais an important player. This project evaluated the mycoflora and bacterialflora of steep cassava with the view of identifying those fungi and bacteriaspecies found with steeped cassava. This research work employed gram stainingreaction or technique and Lactophenol Cotton Blue Stain to...
ABSTRACT The growing global understanding of ecological footprints and environmental pollution invented by humans is gainfully affecting our material design practice, pushing the search for more sustainable alternatives, and development of natural biocomposites. In this research, the natural ability of saprophytic fungi to digest and bind lingo-cellulose is utilized to develop natural biocomposite materials for novel applications in design and architecture. This study aims to provide an insi...
Mushroom is a macro fungus with a distinctive fruiting body which can be either epigeous or hypogeous and large enough to be seen with the naked eye and can be picked with hand (Chang and Milles.19920). Mushrooms derive all of their energy and growth materials from their growth medium, through biochemical decomposition processes (Chang, Shu-Ting, et al. 2004).
BACKGROUND OF THE STUDY All microorganisms are ubiquitous in nature and their interactions with plants, and animals and humans has been recognized for centuries. Some of these interactions are beneficial to the host as in the case of biotransformation such as fermentation and the production of antibiotics. Penicillin, which is one the most famous antibiotics drugs in the world, derived from a common fungus known as Penicillium and it is used to control disease in human and animal population...
ABSTRACT Maize, Zea mays is extensively cultivated in Nigeria with estimated total grain yield of 1.37 million tonnes per year. The maize by-product which includes the cob is readily available. This project was designed to convert maize cob to value-added products in broiler feed through microbial degradation using batch fermentation. One hundred and fifty kilogrammes of maize cob samples were collected from four dump sites in a farmers’ market in Oyo town. Bacteria and fungi were isolate...
Abstract The aim of this study was to identify the occurrence of fungal contamination in different samples of corn (zea mayes) grains in Narok Town. A total of 30 samples were analyzed by direct plating method on a quarter strength potato dextrose agar and focusing on mycotoxigenic fungi.pure cultures of Aspergillus isolates were sub cultured and transferred onto differential media; malt extract agar, czapek yeast extract and czapek dox agar for species identification. The colony were purifie...
Abstract: Anopheles mosquitoes are colonized by diverse microorganisms that may influence hosts‟ biology and vectorial capacity. Resident Anopheles bacterial symbionts isolated from these hosts are known to influence traits such as generational fitness, survival, host seeking,and infectivity of pathogens such asPlasmodium falciparum.Eukaryotic symbionts such as fungi residing in the gut of Anopheles gambiaecould confer similar phenotypes, but are undexplored. It was hypothesized that fungi...
ABSTRACT A laboratory evaluation of cashew nut shell liquid (CNSL) as wood preservative on sapwood of Triplochiton scleroxylon test blocks sawn into 20mm x 20mm x 300mm sizes against Trametes cingulata and Lentinus lepideus was studied using crushing method. The crude extract was diluted with n-hexane, volume for volume. Four levels of CNSL concentration were tested at 4%, 8%, 12% and 16%. The treated test blocks and control test blocks were exposed to the infection regions of the pathogens i...
Abstract: Enset (Ensete ventricosum (Welw.) Cheesman) belongs to the family Musaceae, and is one of the oldest cultivated herbaceous and monocarpic banana-like food security crops in Ethiopia. Microbes which colonize living internal tissues of plants without causing any harm to their host can be used for testing their antioxidant potential under controlled conditions. These microbes protect their hosts from adverse conditions by secreting bioactive secondary metabolites. Therefor, the presen...
ABSTRACT Seven Aspergillus species, A. clavatus, A. flavus, A. Lutn i qe tus, A. niger, A. ochraceus, A. sulphureus and A. ustus have been used to investigate the role of three Coleopteran insect pests, namely, Cal.1osobrochus macula tus, st tophiJ. us zeamais and 'rribo tium castaneum in the persistance and spread of contaminant fungi among grains of maize (Zea mays) and rice (Oryza sativa) and seeds of bambara groundnut (Vigna subterranea) a nd cowpea (Vigna unguiculata). The Aspergi11us sp...
