Abstract: Sustaining fossil fuel and the formation of a sizeable environment are trials maintained through the production of renewable energy as a biofuel. Bioethanol is one of the mainly important alternative sources of energy, which is produced from the several of cheapest materials includes starch, lignocellulose, celluloses, and other different waste materials especially agro waste. Dilute sulphuric acid pretreatment of lignocellulosic material is the main process in ethanol production d...
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: Production of bio-ethanol from Lingocellulosic materials is naturally abundunt renewable resources that can potentially provide a long-term sustainable fuel supply. Prosopis juliflora, an invasive plant is one source of lignocellosic materials to serve as feedstock for bio-ethanol production. With the objective of evaluating its potential for bio-ethanol production, differen concentrations (10g, 20g, 30g, and 40g) of P. juliflora leaves treated with dilute sulfuric acid and untreat...
Abstract: Natural products, especially those of spices origin, have always been an important source of therapeutic agents against chronic oxidative stress-related diseases. This study was aimed to analyse polyphenolic metabolites and antioxidant activity of Ethiopian Clove or kirunfud (Syzygium aromaticum (L.) Merr.) and Fennel or ensilal (Foeniculum vulgare Mill.) extracts. Seeds of fennel and flower of clove were purchased and extraction was done using chloroform, ethyl acetate, methanol a...
Abstract: The present study was intended to investigate phytochemical analysis and antioxidant activities of endophytic fungi isolates from red beetroot (Beta vulgaris L. )Leaf and Root peels . The red beet leaf and root samples were as potential source of endophytic fungi. The surface of samples were disinfectant. Fungal culturing and identifications of genera were made according to fungal identification manual. The phytochemical screening of methanolic extracts of Endophytic fungal isolate...
Abstract: Endophytes demonstrate great potential sources for new bio active compounds. Therefore, the present study was undertaken to assess biological activities including antioxidant and antimicrobial potentials of endophytic fungal extracts from coriander leaves and seeds. The samples were surface sterilized before used as endophytic fungal culture. The result of macroscopic and microscopic characterization of the fungal isolates demonstrated the presence of three genera of endophytic fun...
Abstract: Organic liquid fertilizer not only increases the growth medium ofcrops, but also accelerates the maturation and nutrient quality of the crops. Thus, the present study was aimed at producingorganic liquid fertilizer from banana peels and groundnut husks through aerobic fermentation in open containers. The design of the experment was complete randomized design (CRD) in two replications.Theresults indicated that pH,7.05,EC,0.8,Carbon(C),49.5%,Nitrogen(N),3.62%,C:N,13.71,Phosphorus(P),...
Abstract: A series of ester and ether bridged compounds bearing the nitro and amino moieties were synthesized and characterized, in order to assess their ability to potentially serve as antibacterial agents against drug resistant bacteria. All the compounds were obtained at considerable yields while characterization techniques confirmed their successful synthesis. Furthermore, their antimicrobial assessments showed that all the compounds exhibited antibacterial activity against the Gram-nega...
Abstract: The S2 state produces two basic electron paramagnetic resonance signal types due to the manganese cluster in oxygen-evolving complex, which are influenced by the solvents, and cryoprotectant added to the photosystem II samples. It is presumed that a single manganese center oxidation occurs on S1 → S2 state transition. The S2 state has readily visible multiline and g4.1 electron paramagnetic resonance signals and hence it has been the most studied of all the Kok cycle intermediate...

Abstract: Trypanosomes are protozoans causing African trypanosomiasis, a neglected tropical disease in Africa affecting humans and animals. Despite advancement in African Trypanosomiasis research, the disease continues to threaten millions of people and animals in Sub-Saharan Africa. Control methods have focused on the use of drugs which have adverse effects and vector control methods which have proved to be ecologically unsustainable while vaccines are still not available due to antigenic v...
Abstract: Manduca sexta vitellogenin is a phosphoglycolipoprotein (Mr - 500,000) that contains two copies of the apoproteins (apovitellogenin-1, Mr 180,000 and apovitellogenin-11, Mr 45,000), 13 percent lipids, 3 percent carbohydrates and 0.6 percent phosphorus. The two apoproteins are immunologically distinct polypeptides and apovitellogenin-11 is not completely accessible to the aqueous environment in the intact molecule. The carbohydrate moiety located on apovitellogenin-1 has a high mann...
Abstract: Midgut trypanolysin from Glossina morsitans morsitans was isolated by a combination of an anion-exchange and gel permeation chromatography. The trypanolysin activity was recovered in the bound fraction. The native molecular weight of trypanolysin was determined -669kDa. Analysis oftrypanolysin by SDS-PAGE recovered a single sub-unit ofMr-14kDa. The induction of trypanolysin activity by bloodmeal increased gradually reaching a peak at 72-120 h after the bloodmeal, and then decreased...
Abstract: Trypanosomiasis continues to be a serious problem in sub-Saharan Africa. The inadequacies of existing control strategies necessitate the development of alternative control measures. In most cases, the causative agents of African trypanosomiasis, Trypanosoma spp., require an obligatory passage through the tsetse, Glossina spp (Diptera; Glossinidae ), vector. This developmental step of the parasite leads to vector-parasite interactions, especially within the midgut. Among the vector ...
Abstract: Glossina brevipalpis is a vector of trypanosomes that cause Animal African Trypanosomiasis. Chemoreception in tsetse flies is critical for identifying larvipositioning sites, hosts and mates. Odorant binding proteins (OBPs) are thought to mediate insect chemoreception by shuttling odours to receptors on olfactory sensory neurons. Little is known about the roles of OBPs in tsetse fly chemoreception. The genome of G. brevipalpis has been sequenced and 28 OBPs identified. This study a...
