The increasing global demand for sustainable energy sources has directed attention to biofuel production from renewable resources. This study focuses on the synthesis and characterization of bioethanol from sawdust, an abundant lignocellulosic by-product, using microbial fermentation. Sawdust was pretreated with 0.5 M suphlfuric acid (H2S04) and subjected to microbial fermentation using Saccharomyces cerevisiae. After a week of fermentation at 30°C, the resulting bioethanol was extracted thr...
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: The citrus peel which is almost one half of the total fruit mass is a rich source of phenolic compounds such as flavanones, flavonols and many polymethoxylated flavones. The growing interest of shifting from the synthetic antimicrobial agents to natural ones has encouraged research on screening of plant material and other vegetable sources to identify new compounds. On account of such justification the present study was aimed to examine physicochemical properties, antioxidant and a...
Abstract: Turmeric (Curcuma longa) rhizomes, has been widely used for centuries as indigenous medicine for the treatment of a variety of anti-inflammatory conditions and other diseases. Turmeric and its active components (volatile oil and curcuminoids) have unique antioxidant, antitumorigenic, anticarcinogenic, antiinflammatory, antimutagenic, antiarthritic and antimicrobial properties. This study was aimed to determine the physicochemical properties, antioxidant and antimicrobial activities...
Abstract: Water quality is one of the basic requirements for human health, development and wellbeing. The study was conducted from December 2021 to March 2022 to determine the physicochemical and microbial quality of drinking water in Addis Ababa city. A total of 1353 water samples were collected from eleven sub city drinking-water sources in three rounds such as 825 from tap water, 132 from well water, and 396 from reservoirs water sources. All the collected data were processed and compared...
Abstract: Plectranthus amboinicus is knowns us traditional plant medicine in dif erent rural and urban community. However, production and usage of this traditional medicines require a scientific techniques and supports for the appropriate development of antibacterial drugs. The current study was intended to investigate phytochemical screening and antibacterial activities of Plectranthus amboinicus crude extracts, against pathogenic bacteria using the disc dif usion method. The minimum inhibi...
Abstract: Many smallholder farmers in the developing world live in adverse poverty, and rely on agriculture as their primary source of income and household food. In Zambia agriculture production is the main activity for people in rural areas of the country. The study evaluated the effects of climate-smart practices; Gliricidia sepium Alley cropping, conservation agriculture Basin, Ripping and conventional agriculture cropland on selected physicochemical properties of soil and crop productivi...
Abstract: This dissertation work was aimed to investigate the biochemical and functional properties of soft brined cheese made from camel milk and it is composed of four different papers. The papers are a review article on camel proteins technological functionalities and three experimental papers. In the first experiment, operating parameters for camel milk gelation kinetics (i.e. pH, temperature, coagulant (camel chymosin) concentration and CaCl2 addition) to optimize the recipe for cheese ...
Abstract: A total of 180 Cobb 500 day old broiler chicks were randomly distributed into 15 pens. Five different rations consisting different inclusion levels of Tomato Waste Meal (TWM) were prepared and randomly assigned to treatments to evaluate the growth performances, carcass characteristics and selected hematological and serum biochemical parameters of the chicks. The inclusion levels of TWM were 0% (T1), 3% (T2), 6% (T3), 9% (T4) and 12% (T5). The experiment was conducted for a period o...
