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: Biosorption is the most promising technique to decolorize, separate, and pre-concentrate liquid and gaseous mixtures to facilitate the removal of harmful chemicals because of its efficacy, easy operation, non-toxicity, and mild reaction condition. The present study was carried out to assess the efficacy of coffee husk in the biosorption of reactive Congo red dye. Coffee husk samples were collected from coffee shop in Harar City, Ethiopia. The biosorbent materials were prepared from...
Abstract: This study was to investigate medicinal plants used to treat Human Ailments by local community in Bedeno woreda,East Hararghe,Oromia,Ethiopia,The study was conducted in Bedeno Woreda, East Hararghe Zone of Oromia Regional State, Ethiopia. The data were collected from traditional medicine practitioners using group discussions, semi-structured interviews, and field observations and analyzed using informant consensus factor, preference Ranking and fidelity level. A total of 30 medicin...
Abstract: Biomaterials have been used as biosorbents either in raw or chemically modified forms. The main aim of the present research work was to synthesize activated biocarbon from leaves and seeds of Lantana camara as biosorbent of heavy metals from wastewater effluent. The biocarbon was functionally characterized by Fourier transform infrared (FT-IR). The biosorbent potential of the biocarbon material was determined based on removal of heavy metal contaminants. The florifarm water sample ...
Abstract: Deforestation and forest degradation affect livelihoods variously including diminished ability of forests for climate mitigation. This study aimed to estimate vegetation structures, species diversity and carbon stocks potential of Dzalanyama Forest reserve in Malawi. A forest inventory was conducted in 31 concentric cluster sample plots. Trees ≥ 5cm Diameter at Breast Height (DBH) were recorded and identified to species level. Floristic composition and diversity were evaluated. S...
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: In developing countries, the value of traditional medicinal plant species gaining popularity as it is inexpensive compared to the modern health services. Hence, the purpose of this study was to identify traditional medicinal plants and related indigenous knowledge of the study area. Ethnobotanical data was collected from February to March, 2022 using 86 ordinary and 14 key informants through semi-structured interviews, and guided field for field observations to select potential keb...
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: Heavy metal is a general collection term applying to the group of metals and metalloids with an atomic density greater than 6g/cm3 and are mainly associated with pollution problems.The purpose of this study was to conduct analysis of heavy metal accumulation in the edible muscles of Nile Tilapia and Ccurican carp fish species which are among the most common types of fish consumed by the local people and found widespread in the lake.The water and fish samples were purposively collec...
Abstract: There is a potential of medicinal and wild edible plants (WEP) species lore in the Dire district of Borana Zone, which was unexplored for scientific investigation, conservation and sustainable utilization. Therefore, this ethnobotanical study was conducted to explore these potential biodiversity resources in the study area. A total of 136 respondents were selected to collect ethnobotanical data on medicinal and WEP species from four sampled Kebele’s locally called Areda (the smal...
Abstract: This study was aimed to investigate the shelf-life and rheological properties of cottage cheese made from camel milk as physicochemical properties, microbial counts and texture. The experiment was laid out in completely randomized design (CRD) with eight treatments. The general chemical composition of milk including fat, solids-not-fat (SNF), protein, total solid, casein and lactose were determined using MilkoScan. Cheeses were made in the dairy technology laboratory of Haramaya Un...
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: Birds are among essential taxa in various ecosystems where their presence/absence and status indicate conditions of the habitats. Hence, a detailed understanding of species biogeography, diversity, and abundance is critical ecological information to evaluate or develop conservation strategies. The present study was conducted during dry and wet seasons from March 2021 to April 2021 and June 2021 to July 2021, respectively, to assess species diversity and abundance of avifauna as pot...
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 ...
