Biogas Production from CO-digestion of cow dung and Barley straw

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...

IN VITRO EVALUATION OF ANTIMICROBIAL ACTIVITIES OF ALOE VERA (L.) LEAF EXTRACT ON SELECTED HUMAN SKIN PATHOGENS

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...

ISOLATION AND CHARACTERIZATION OF LACTIC ACID BACTERIA FROM THE GASTROINTESTINAL TRACT OF HONEY BEE (Apis mellifera yementica) FOR PROBIOTIC APPLICATION

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...
