Identification of Catechin as One of the Flavonoids from Combretum albiflorum Bark Extract That Reduces the Production of Quorum-Sensing-Controlled Virulence Factors in Pseudomonas aeruginosa PAO1
Quorum-sensing (QS) regulates the production of key virulence factors in Pseudomonas aeruginosa and other
important pathogenic bacteria. In this report, extracts of leaves and bark of Combretum albiflorum (Tul.)
Jongkind (Combretaceae) were found to quench the production of QS-dependent factors in P. aeruginosa PAO1.

The impact of pond depth and environmental conditions on sunlight inactivation of Escherichia coli and enterococci in wastewater in a warm climate
MAIGA Ynoussa, WETHE Joseph , DENYIGBA Kokou , OUATTARA Aboubakar Sidiki
Microcosm experiments were carried out under dark and real sunlight conditions in Ouagadougou (Burkina Faso) to investigate the survival of faecal indicators (Escherichia coli and enterococci) in secondary wastewater. Light damage was estimated by loss of bacterial culturability. The results clearly show that sunlight has a deleterious effect(...)

Biodepollution of wastewater containing phenolic compounds from leather industry by plant peroxidases
Mamounata Diao • Nafisse´tou Oue´draogo • Lamine Baba-Moussa • Paul W. Savadogo • Amani G. N’Guessan • Imael H. N. Bassole´ • Mamoudou H. Dicko
This study deals with the use of peroxidases (POXs) from Allium sativum, Ipomoea batatas, Raphanus sativus and Sorghum bicolor to catalyze the degradation of free phenolic compounds as well as phenolic compounds contained in wastewater from leather industry. Secretory plant POXs were able to catalyze the oxidation of gallic acid, f(...)

In Vitro Antiplasmodial and Antibacterial Activities of Canthium multiflorum Schum & Thonn (Rubiacea) Extracts
Akomo EF, Zongo C, Karou SD, Obame LC, Savadogo A, Atteke C, Traore AS
Because of the resistance of pathogens to actually available drugs, there is a continuous need for new agents to cure several diseases such as malaria and microbial infections. In the establishment of new drugs, plant are often a source of new leads, indeed aqueous, acetone and methanol extracts of Canthium multiflorum were tested for antiplas(...)

Sunlight inactivation of Escherichia coli in waste stabilization microcosms in a sahelian region (Ouagadougou, Burkina Faso)
MAIGA Ynoussa , DENYIGBA Kokou, WETHE Joseph, OUATTARA Aboubakar Sidiki
Experiments on sunlight inactivation of Escherichia coli were conducted from November 2006 to June
2007 in eight outdoors microcosms with different depths filled with maturation pond wastewater in
order to determine pond depth influence on sunlight inactivation of E. coli. The long-term aim was to
maximize sunlight inactivation of waterborn(...)

Mutualism between euryhaline tilapia Sarotherodon melanotheron heudelotii and Chlorella sp. Implications for nano-algal production in warmwater phytoplankton-based recirculating systems
Gilles S.; Lacroix G., Corbin D., Bâ N’G., Luna C I., Nandjui J., Ouattara A., Ouédraogo O., and Lazzaro X.
The West-African euryhaline tilapia, Sarotherodon melanotheron heudelotii shift from visually feeding on
zooplankton when juveniles to mostly filter feeding on phytoplankton when adults. When reared using
an appropriate ration in intensive aquaculture systems, S. m. heudelotii also consume algal-based detritus,
and contribute to sediment mi(...)
