Abstract: Back ground.Water is the essence of life. A clean and safe drinking water supply may be the norm in European and North American countries, but in developing countries the assessment of both clean and safe drinking water (DW) is not the rule and hence waterborne illness outbreaks are common. Objective:This study was conducted to assess the microbiological quality of drinking water collected from different sites in Dhera town during July-December 2022.During this period a total of 42...
Abstract: Microbial proteases are hydrolytic enzymes that are widely used in many industrial processes. This study aimed to evaluate the production of alkaline protease (AP) from fungal isolates sourced from avocado (Persea americana Mill.) peel (AVP) and avocado seed (AS) under solid state fermentation (SSF). AVP and AS was collocated form Harar juice house into plastic bag and serial diltuion method was used for fungal isolatin. The isolates were subutured on potato dextrose agar (PDA) and...
Abstract: Biogas production is one of the technologies that can overcome the problems related to energy Crisis. Therefore, this research was conducted to investigate the biogas production potential of Xanthium strumarium leaves in combination with goat manure in anaerobic condition. Completely randomized experimental design was used under mesophilic condition (38ºC). Five batch fermentation treatments (T1=100% goat manure, T2=75% goat manure:25% Xanthium strumarium, T3=50% goat manure:50% X...
Abstract: Pectinase is a heterogeneous group of enzyme which hydrolyzes pectin. Fungi and actinomycetes have ability to produce a large amount of industrial enzymes. Therefore the present study was undertaken production of pectinolytic enzymes from barley (Hordeum vulgare Von. Bothmer) and wheat (Triticum turgidum L.Von) locally called (Garbu or Qamadi) hulls. Wheat and Barley Hulls samples were collected from homes. Isolation of the fungal species was done on czapek-dox-agar media. Fungal i...
Abstract: Energy is one of the most important factors for human development and global economic growth. Renewable energy techniques give a great opportunity for the reduction of greenhouse gas emissions and decreasing global warming via replacing traditional energy sources. Biogas is a clean, environmental friendly and renewable form of energy generated when micro organisms degrade organic materials in the absence of oxygen. This study was aimed to evaluate the biogas production potential of...
Abstract: Alkaline proteases are one of the classes of protease enzymes which are extensively used in detergent and tanning industries. Currently, there is an increasing demand for biocatalysts from extreme environments that are important sources of microorganisms routinely used in novel industrial enzyme production. In this research attempts were made to isolate and screen for an alternative alkaline protease producing fungal species from abattoir and food wastes. Hence, fungal species were...
Abstract: Lignocellulosic biomass is one of the most suitable alternative energy sources, whichcan be harnessed to meet the challenges of energy security. Energy resources such as petroleum and coal are being utilized at a rapid rate and eventually run out. Therefore, this research was initiated to find an alternative substrate for the production of ethanol from a cost-effective substrate. Parthenium leaf and stem were collected from Haramaya University. The collected Parthenium leaf and ste...
Abstract: Watermelon is one of the major utilized fruits grown in the warmer part of the world. The juice or pulp from watermelon is used for human utilization, while rind and seeds are major solid wastes. Endophytic microbes have been an important and potential resource of bioactive compounds. The present study was undertaken to assess phytochemical analysis, antioxidant and antimicrobial activities of endophytic fungal isolates from water melon seeds and fruit rind. The watermelon seed and...
Abstract: Laccase (EC 1.10.3.2, benzenediol oxygen, oxidoreductases) is typically extracellular monomeric glycoproteins that belong to the multicopper oxidase family. Laccase is widely distributed in higher plants, bacteria, fungi, and insects. Laccase play an important role in different industrial sectors, soil bioremediation and biodegradation of environmental phenolic pollutant and removal of endocrine disruptors. Laccase has been efficiently applied to nanobiotechnology due to their abil...
Abstract: Bioactive natural compounds isolated from fungal endophytes have been playing a promising role in the search for novel drugs and becoming an inspiring source for researchers due to their enormous structure diversity and complexity. Therefore, the present study was undertaken to assess antioxidant and antimicrobial activities of endophytic fungi from garlic bulbs and leek leaves. The study involved garlic (Allium sativum) bulb and leek (Alllium Ampeloprasum var. porrum) leaf samples...
Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative eco-friendly renewable energy source. Anaerobic digestion is a technology widely used for the treatment of organic waste for biogas production. Therefore, the study was conducted to investigate the production of biogas from Wild oats co-digested with goat manure through anaerobic digestion with five treatments. The treatments were made into five treatments by mixing substrates in dif...
Abstract: This research was conducted with the objective of developing yogurt from camel milk using exopolysaccharides producing lactic acid bacteria, starch and camel milk powder to improve the texture and other quality characteristics of the product and to evaluate the sensory values of consumer’s acceptability. The experiment was conducted as Completely Randomized Design with one way Analysis of Variance. Physicochemical properties of raw camel milk and yogurt, viscosity, syneresis, tex...
Abstract: Artificial insemination technology of dairy cattle is a popular technology to improve the performance of new breeds. But, the adoption and utilization of the technology by dairy cattle owners in Ethiopia in general and study area in particular is very low. This study was conducted in Bedele Woreda of Buno Bedele zone of Oromia National Regional State with the aim of assessing determinants of adoption decision and intensity use of artificial insemination technology of dairy cattle. ...
Abstract: A study on characterization of milk cattle production potential, milk processing, marketing and chemical composition analysis were conducted in Agarfa District of Bale Zone. For this study two rural and two peri-urban milk production potential kebeles and total of 150 respondents from study were purposively selected. Data were collected through interviewing selected farmers, from field visit, focal group discussions, monitoring and laboratory analysis supported with secondary infor...
Abstract: Tasmanian devils are the largest living carnivorous marsupial found in the wild of Tasmania. These species are being threatened by a cancerous tumour disease, the Devil Facial Tumour Disease (DFTD). The disease affects the facial areas and has led to a considerable popula tion decline. In this thesis, mathematical models for transmission of DFTD are developed and analysed to investigate the significance of feeding and mating related contact, optimal control and fractional-order cha...
