Abstract: Fermentation is a metabolic process of microorganisms to obtain energy by breaking down organic compound. Potato peel waste was fermented with different concentration substrate (1gm, 2.5gm, 5gm, 10gm, 15gm, 20gm and 25gm) with 1% yeast and pH4.5 in different fermentation period (4th day, 8th day, 12th and 16 th days) with the aim of optimizing the substrate concentration for ethanol production. Among the different substrate concentration 10 gram of substrate produced more quantity ...
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: Fruit are very important for human being which contribute vital nutrients especially Vitamin C. However Fruit which are contaminated during harvesting and transporting. From different area. poor hygienic conditions, using of tap water for cleaning and unsafe environmental conditions of fruit resulting in different food borne illnesses. The study was aimed to assess bacteriological load of fruit served in cafes and restaurants of Chiro town. A cross sectional study was conducted fro...
ABSTRACT Cement is subject to degradation by aggressive media found in the environment. Durability tests are therefore necessary for any cementitious material in a given aggressive environment. This study investigated chloride and sulphate diffusivity in mortar made from selected Kenyan cements. The test cements included three brands of Ordinary Portland Cements (OPC) and three brands of Portland Pozzolana Cements (PPC). The test cements were used to make mortar prisms at different water / ce...
ABSTRACT Anopheles gambiae mosquitoes are vectors of malaria because of their ability to transmit Plasmodium falciparum parasites. The major impact of malaria is in sub-Saharan Africa where at least 90% of the deaths from malaria occur. In Kenya, malaria accounts for 30% of all outpatients and 19% of all admissions to health facilities. Malaria can also affect the quality of labour negatively and also can lead to low productivity through absenteeism. Anopheles gambiae is the vector associated...
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 Microbial diversity and function in agro-ecosystems is influenced by various aspects linked to soil and agronomic practices for example, tillage, irrigation, crop rotation and application of organic and inorganic inputs. Farming systems practices may affect the dynamic interactions existing between soil, plant and microorganisms in different agricultural biomes. Due to limitations associated with conventional microbial cultivation strategies, only a fractional number of cultivable sp...
This work concerns one of the most important tools to solve well-posed problems in the theory of evolution equations (e.g diusion equation, wave equations, ...) and in the theory of stochastic process, namely the semigroups of linear operators with application to dierential equations.
ABSTRACT Yersinia enterocolitica and Yersinia pseudotuberculosis are important food and water borne pathogens that has recently emerged world wide. This study was aimed at characterizing the prevalence of Yersinia enterocolitica and Yersinia pseudotuberculosis in human and selected animal populations in Jos and its environment. Three thousand stool samples from human and selected animal species from 5 different locations in Jos and its environs were surveyed over a period of three years. Huma...
Abstract Over the years, nomadic Fulani herdsmen have established different settlement camps outside the traditional villages of their indigenous host communities in Ebonyi State. With increasing concerns about the health condition of the nomads, this study was undertaken to investigate the prevalence and distribution of some microbial and parasitic infections amongst the spartially distributed population of the nomadic Fulani herdsmen in Ebonyi State. This investigation was carried out betwe...
Mature apple trees were sprayed using a Knapsack mistblower fitted with 3 different nozzle systems, one of which provided an induced electrostatic charge on the spray droplets. Spray distribution was assessed by examining fluorescent tracer deposits on Kromekote cards which had been positioned in different parts of the tree canopy. Subsequently, bioassays with codling moth (neonate larvae) and formulations of cypermethrin examined the biological effect of deposits. Small uncharged droplets (3...
A parasitological examination of 2,500 faecal samples of cattle was carried out in Plateau State, Nigeria, to determine prevalence, seasonal distribution and sources of various species of Eimeria in both sexes, age groups, breeds and husbandry systems. Effects of temperatures on sporulation of Eimeria oocysts and chemical analysis of the Eimeria oocysts were also determined. Out of 2500 samples examined, 1567 i.e 62.68% were positive for twelve species of Eimeria. E. alabamensis occurre...
ABSTRACT Acute lower respiratory tract infection (ALRTI) in children under five years is predominantly cause by Respiratory syncytial virus (RSV) but in recent times Human Metapneumovirus (HMPV) has also been implicated in ALRTI. In Ghana, the few studies on ALRTI have focused on the prevalence of RSV and the viral etiological agents causing acute bronchiolitis, bronchopneumonia and pneumonia. This cross sectional study sought to detect, characterize and genotype respiratory syncytial virus ...
ABSTRACT The emergence of multiple antibiotic resistance in bacteria and the indiscriminate use of antibiotics contribute to the dissemination of resistant pathogens in the environment which may cause problems in therapy and is a serious public health issue. This study was conducted to determine the incidence of Pseudomonas aeruginosa in clinical samples and their antibiotics resistant pattern. The organisms were isolated using standard microbiological techniques and the antibiotic susceptib...
ABSTRACTEucalyptus camaldulensis is an important medicinal herb in traditional healthcare practice and has been reported for various biological activities. The objective of the present study was to analyze the antibacterial potentials and toxicity study of E. camaldulensis leave extracts against clinical isolates of salmonella species. The E. camaldulensis leaves were extracted separately and successively with ethanol, water and methanol using percolation method. The extracts were tested in v...
