Abstract: Tella” is one of the important Ethiopian traditional beverages, which is prepared from different ingredients. Ingredients of tella are one of the major important sources of the isolation of dominant yeast from the local alcoholic beverages. Hence, this study was conducted to determine the major source of dominant yeast cells by identifying them in the ingredients of tellasuch as; gesho, bikil, tense, difdif and compared within that of bakery yeast. The collected samples were proc...
Abstract: Grapes (Vitis vinifera L.) are among the most widely consumed fruits for its asociated health benefits. Endophytic fungi are groups of fungi with very specific ecosystem inside plant tissues and produces varieties of secondary metabolites with medicinal and nutraceutical applications. The present study was undertaken to investigate production of bioactive extracts with antioxidant and antimicrobial potentials activities of endopytic fungi from red grape peel and seed. The antioxida...
Abstract: The brewery industry consumes daily a large volume of water and chemicals and generates a high amount of nutrient-rich wastewater. The discharge of this wastewater into the environment without proper treatment causes serious and prolonged ill consequences on the ecosystem. Thus, the objectives of this study were to assess the physicochemical characteristics of Harar Brewery effluent; to isolate, identify and determine the efficiency of the indigenous bacteria in removing or reducin...
Abstract: Non-Typhoidal Salmonella represents an important human and animal pathogen world-wide. Most human non-typhoidal Salmonella (NTS) cases are foodborne, but each year infections are also acquired through direct or indirect animal contact. Epidemiological information on the prevalence of Salmonella is a prerequisite to develop appropriate control strategies. A cross sectional study was conducted from July 2022 to January 2023 to isolate and perform Antimicrobial susceptibility test of ...
Abstract: This study was intended to investigate the antioxidant and antimicrobial activities of endophytic fungi isolates from coffee husks. The coffee husk sample was collected from the local processor in Nensebo district, Arsi Zone, Ethiopia. The samples were surface sterilized before used as endophytic fungal culture. The nutrient value was prepared as per manufacturer instructions. Fungal culturing and identifications of genera were made according to fungal identification manual. Then, ...
Abstract: Potato is one of the most staple food sources for many people worldwide. The inoculation of antagonism with potatoes plays a very important role in the worled due to its contribution for human consumption. The rhizosphere is an important source of microbial antagonistic against soilborne fungal pathogens Rhizoctonia solani.This study focuse on the assessment of microbial antagonism in rhizosphere and non-rhizosphere of potato through investigation of potential microbial antagonism ...
Abstract: The rising global population pressure generates challenges to fulfill food requirements for the coming generations in adequate amounts. This suggests that the human population cannot continue to be entirely dependent on crops, animal husbandry and fisheries for food. Instead, efforts should be made to enhance the production of other potential alternative sources of food. To this end the current study has been undertaken to evaluate the production of single cell protein (SCP) from A...
Abstract: Enzymes are biological catalysts, which initiate and speed up thousands of biochemical reactions in living cells. Among industrially important enzymes, amylases, protease and cellulases are getting more attention and importance because these enzymes have wide applications in many fields. For instance, amylases are used in various industries such as food, detergent, paper, textile, beverage, pharmaceutical and fine-chemical industries. Thermophiles are a potent source of thermos enz...
Abstract: The study was conducted to evaluate and characterize cultured Dhanaan (camel milk fermented using commercial starter cultures) with the following objectives; evaluation of the microbial safety of traditionally fermented Dhanaan, evaluation of the acidification activities of commercial starter cultures in camel milk, proteomic/peptidomics characterization of cultured Dhanaan and aromatic characterization of cultured Dhanaan. Shotgun metagenomic approach of 16S rRNA gene amplicon was...
Abstract: Most rural populations in developing countries use surface water which is turbid in appearance and contaminated with human feces which needs treatment. Even if there are synthetic chemicals that can reduce turbidity and pathogenic organisms from drinking water, they are neither cost effective nor eco-friendly. Instead, natural coagulants are eco-friendly solutions with minimum health risks if properly tested and promoted to be used by community dependent on such unsafe water source...
Abstract: Frequent use of antibiotics to stimulate growth and health of animals is becoming a common animal production practice. However, this leads to the development of antibiotic-resistant populations of microorganisms. In this context, alternatives like herbs and spices to antibiotics are of importance, as they are natural products. Therefore, the purpose of this study was to (1) evaluate the effects of Lepidium sativum (Garden cress, GC, Experiment I) and Capsicum frutescens (Hot red pe...
Abstract: The experiment was conducted at Haramaya University compound, to evaluate three beneficial local microorganism (BLM) harvesting protocols and the effect of application rate and ensiling period of barley straw (BS) with beneficial local microorganism solution on its silage quality. The three procedures Niva, Rodrigueze and Davenport were used for production of beneficial local microorganism solution with three replication in a completely randomized design for each treatment (procedu...
Abstract: The study was conducted in Selale-Addis, Ambo-Woliso, and Adama-Asela milk sheds in Ethiopia with the objective to investigate milk postharvest losses, their causes, mitigation strategies, physicochemical, compositional, microbial quality, and safety of raw milk, and their effects on household income and per capita milk consumption in the study area. The three milk sheds were purposively selected based on their potential for milk production, whereas households were selected randoml...
Abstract: Antibiotic resistance genes (ARGs) and antibiotic resistant bacteria (ARB) have been globally considered emerging environmental contaminants that pose a serious concern to human health and the ecosystem. The ubiquitous nature of ARB and ARGs among pathogens from wastewater effluents, indicate that wastewater treatment facilities are major reservoirs for antibiotic resistance determinants, thus contributing to the widespread dissemination of antibiotic resistance. The primary object...
Abstract: Antimicrobial resistance (AMR) is regarded as a global health threat, characterized by rising resistant bacteria and rapid development of resistance genes to existing antibiotics used in clinical and veterinary settings. AMR has negative impacts and affects human, animal, and the environment. In Botswana, Africa, AMR is not well understood, particularly in rural settings with poor sanitation. The misuse and overuse of commonly used antibiotics like ß-lactam antibiotics, combi...
