Abstract: Organic Liquid Fertilizer made from the decomposition of organic material such as plant residue and animal waste through anaerobic fermentation comprises number of growth substances, vitamins, antibiotics, amino acids and useful micro-organisms. The advantage of these fertilizers resolve a deficient of nutrient and provide the additionally faster nutrient supply. Thus, the present study was aimed to produce organic liquid fertilizer from cow manure and groundnut husks through aerob...
Abstract: Natural organic fertilizers used in plant cultivation are characterized by low efficiency and soil-applied in large quantities to obtain high yield. The bioorganic fertilizer obtained through anaerobic fermentation comprises number of growth substances, vitamins, antibiotics, amino acids and useful micro-organisms. Bioorganic liquid fertilizer not only increases bioorganic fertility of crops (in comparison to the control and prototype fertilizer), but also accelerates their maturat...
Abstract: Biogas is an eco-friendly renewable energy source through the anaerobic digestion of organic waste materials. In this study, biogas production from co-digestion of Bidens pilosa(BP) and poultry Manure (PM) in five mix ratios (100%BP, 75%BP:25%PM, 50%BP:50%PM, 25%BP:75%PM and 100%PM) were evaluated under at 38ºC using a batch mode digester over 21 days of fermentation. In all treatments, physico-chemical parameters such as pH, total solid, volatile solid, moisture content, organic ...
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...
