Currently, pollution caused by petroleum products remains a critical concern. Among the various methods employed, bioremediation is most widely utilized technique to address this issue. To implement technique, we must continue research and identify strains of microorganisms capable degrading these pollutants. Thus, study aimed test biodegradation capacity two bacterial strains. For this, morphological biochemical characterization was done using standard methods. Then, genetic performed...

Cells were Gram-stain-negative, motile rods with single polar flagellum and type II intracytoplasmic membrane arrangement. The grew on methane or methanol as the sole carbon energy source. It at 15–37 °C (optimum 25–30 °C), pH 6.0–9.0 7.0–8.0) 0–0.1 % (w/w) NaCl (no growth 0.5 above). formed cysts, but not exospores. results sequence analysis 16S rRNA gene indicated that...

Dans la vallée du Sourou, des enquêtes parasitologiques portant sur prévalence parasitoses intestinales ont été menées entre 2000 et 2002 dans les villages traditionnels de Wèrè, Toma-île, Yayo, Touroukoro, Di, Oué Sono situés respectivement le cours d'eau au bord lac pour cinq premiers, à une dixaine kilomètres deux derniers. Les également concerné sites aménagés Débé, Guiédougou Niassan. Afin déterminer l'intensité concernés, selles 1142 enfants âgés 0 16 ans examinées. résultats...

Safe drinking water access for rural populations in developing countries remains a challenge sustainable development. The study aims to investigate the quality and factors affecting this Sourou valley Burkina Faso. A total of 135 samples were collected sterile glass bottles during dry seasons 2007, 2008, 2012 from 10 drillings 5 wells. Fifteen physicochemical parameters two fecal pollution indicators (Escherichia coli Coliforms) monitored based on laboratory standard methods. Datas analyzed,...

Biomethane potential production from cashew nut hulls, an agricultural waste, was carried out using old and fresh hulls as substrates. Samples were taken (around 8 years old) produced in scale transformation units at Bobo Dioulasso/Burkina Faso. Physicochemical parameters showed that can be a good candidate for anaerobic digestion. But high acidity, total phenols lignin tenor could constraint bacteria. Theoretical biochemical methane value of 666.937 CH4 L. (Kg VS)-1 526.206 crushed powdered...

Despite great progress in schistosomiasis control over the past decade Burkina Faso, this disease remains a public health problem. This study analyzes parasitologic data from investigations of Schistosoma haematobium, S. mansoni, and mollusks. The prevalence rate haematobium varies 3.3% to 50.4%; that for mansoni (tested only western part country) 39.1%. Prevalence rates are higher school-aged boys than girls, but reverse is true among adults. Studies mussels showed presence Biomphalaria...

Iron toxicity is one of the main edaphic constraints that hamper rice production in West African savanna and forest lowlands. Although chemical reduction processes various types pedogenic iron oxides could not be underestimated, bulk these can ascribed to specific activity Iron-Reducing Bacteria (IRB). The reducing conditions waterlogged lowland soils boost through almost all into ferrous form (Fe2+), which cause disorder plant crop yield losses. Aiming contribute at improvement Africa, an...
