Abstract: Biogas can be produced from any biodegradable feedstock that is suitable for anaerobic digestion. In present day biogas production from barley straw and cow dung was investigated using the number of small reactors. Barley straw was codigested with Cow dung with the aim of biogas production. Five treatment mixtures of Barley straw and Cow dung in ratio of 100% Barley straw(BS), 70% Barley straw(BS) and 30% Cow dung(CD) , 50% Barley straw(BS) and 50% Cow dung(CD) , 30% Barley straw a...
Abstract: Aloe vera is one of a medicinal plant that used traditionally to treat a number of diseases. Hence, this study was conducted to evaluate antimicrobial activities of Aloe vera (L.) leaf and gel extract in different solvents like Ethanol, Petroleum ether and Distilled water (aqueous) against selected human skin pathogens namely; Streptococcus pyogenes, Streptococcus agalactiae and Aspergillus flavus. Disc diffusion method was used to achieve antimicrobial assay. Minimum inhibitory, b...
Abstract: Lactic acid bacteria are widely used as probiotics. Probiotics are beneficial components of the microbiota that have been used for centuries throughout the world because of the health benefits they confer to the host. Isolation and characterization of probiotic lactic acid bacteria is essential not only for understanding their individual contribution to fermentation processes but also to reveal their roles in industrial applications. The aim of this study was to isolate and charact...

The banana peel is nutritional and rich in phytochemical compounds than its pulp. Characterization of the physicochemical; antioxidant and antimicrobial activities of oil extracted from unripe green and yellow ripen banana fruit peels and pulps and appraisal of its viability is the main purpose of this study. In this work, In this work,In this work,In this work, In this work...
Abstract: Soil- transmitted helminth parasite infections constitute major public health challenges among school children in developing tropical and sub-tropical countries. The objective of the present study was to determine the prevalence and factors associated with soil transmitted helminth parasite infections among school children in Meti Primary School of Oromiya Region, Ethiopia. The study was school based cross sectional survey, involving 408 participants (203 males and 205 females, age...
Abstract: Medicinal plants have been used for centuries to treat diseases. Differences in antimicrobial activities may affected by geographical area and other conditions.This study was carried out to screen the phytochemical composition and antimicrobial activities of leaf,friut and root extracts of U.dioca against pathogenic bacteria and fungus. U.dioca is a medicinal plant which belongs to the family Urticaceae.The Leaf,friut and root of this plant were collected. The phytochemical screeni...
Abstract: Biogas technology, which is meant to produce methane rich gas through anaerobic digestion of biological materials, is an environmentally friendly technology that decreases environmental pollution through decomposing organic wastes and positively impacts the socio-economy of the society. Therefore, the research was conducted to investigate the production of biogas from corn Stover co-digested with goat manure through anaerobic digestion. In this study, five different proportions of ...
Abstract: Carica papaya (L.) is a monoecious, dioecious or hermaphrodite tree; it belongs to the family Caricaceae. It is widely cultivated throughout the world and is used as food and traditional medicine, particularly as an antiseptic and contraceptive. Papaya contains many biologically active compounds. Fruits, leaves, latex and stems are used to treat indigestion, diarrhoea, stoppage of urination, blindness and alopecia. The aim of this work was to assess the physicochemical properties, ...
Abstract: The study was conducted in Dabal forest to investigate the floristic composition, population structure and regeneration status of woody plant species (WS) in the forest. 52 nested quadrats of the size 20m × 20m, 10m x 10m and 5m × 5m for tree/shrub, sapling and seedling respectively, were laid systematically along seven line transects. For each quadrat, variables such as altitude, longitude and latitudes were recorded by using Garmin 62 GPS. A metermarked stick was used to measur...
Abstract: In most cases invasive plants have allelopathic effects on crops and other indigenous associated plants. Allelochemicals from such plants may also have negative impact on soils. This study was carried out to investigate the allelopathic effect of leaf extracts of Lantana camara and soils invaded by it on Lepidium sativum. Leaf extracts of Lantana camara were prepared in 5, 10, 15 and 20% concentration levels while distilled water was used as control to evaluate germination paramete...
Abstract: Parasite infections are a disease conditions associated with the presence of parasite in a host’s body. And It is believed that infections caused by parasites have an effect on hematological parameters. Hence this study was designed to investigate the effect of intestinal parasites infections on Packed Read Cell Volume (PCV), Hemoglobin (Hb) concentration, and blood groups frequencies as well as to investigate the intestinal parasite prevalence among school children. Stool and bl...
Abstract: Fermentation is a metabolic process of microorganisms to obtain energy by breaking down organic compound. Potato peel waste was fermented with different concentration substrate (1gm, 2.5gm, 5gm, 10gm, 15gm, 20gm and 25gm) with 1% yeast and pH4.5 in different fermentation period (4th day, 8th day, 12th and 16 th days) with the aim of optimizing the substrate concentration for ethanol production. Among the different substrate concentration 10 gram of substrate produced more quantity ...
Abstract: Irish Potato (Solanum tuberosum L.) is one of the world’s most economically important tuber crops belonging to the family Solanaceae. It is a versatile vegetable that is eaten all around the year. The objective of this study was to establish a protocol for in vitro micropropagation of Gudene and Belete Irish potato varieties from lateral bud explants. For shoot induction lateral buds of Gudene and Belete were cultured on MS basal medium that contained 30 g/l sucrose, 6 g/l agar, ...
Abstract: This study evaluated the antimicrobial activities and the physicochemical characteristics of five honey samples (White, Red, Yellow, Black, and Mixed) from Wollayta, Ethiopia. The agar dilution method was used to assess the antibacterial activities of honey against S.Typhimurium and E.coli strains. Microbial growth inhibition was determined by measuring the diameter of clear zone of microbial growth around the well in the agar. The mean inhibition zone diameters (mm) for White, Red...
