Photoacoustic Approach to Direct Determination of the Total Phenolic Content in Red Sorghum Flours
DOKA, O.; BICANIC, D. D.; Mamoudou H. DICKO and Slingerland, M. A.
Photoacoustic (PA) spectroscopy in the ultraviolet and visible was demonstrated to be a suitable tool for direct determination of total phenolic content in red sorghum flours. The PA spectra obtained feature two characteristic peaks: the first centered at 285 nm is due to the aromatic amino acids, while the second one at 335 nm is associated w(...)

Antimalarial activity of Sida acuta Burm. f. (Malvaceae) and Pterocarpus erinaceus Poir. (Fabaceae)
KAROU, D., Mamoudou H. DICKO, Sanon, S., Jacques, SIMPORE, Traoré, A. S
Among strategies to combat malaria, the search for new antimalarial drugs appears to be a priority. Sheering for new antimalarial activities, four plants of the traditional medicine of Burkina Faso: Combretum micranthum, Khaya senegalensis, Pterocarpus erinaceus and Sida acuta, were tested in vitro on fresh clinical isolates of Plasmodium falc(...)

RIA systems were developed and used to measure pregnancy-associated Glycoprotein (PAG) concentrations during gestation and the postpartum period in Azawak Zebu cows. Twelve females were palpated per rectum and diagnosed as pregnant. Blood samples were taken at 5±10-day intervals from approximately Week 8 of gestation until Week 10 postpartum ((...)

Bosea minatitlanensis sp. nov., a strictly aerobic bacterium isolated from an anaerobic digester
Aboubakar S. Ouattara, Essokazi A. Assih, Sebastien Thierry, Jean-Luc Cayol, Marc Labat, Oscar Monroy and Herve´ Macarie
A strictly aerobic, mesophilic bacterium, strain AMX 51T, was isolated from anaerobic digester sludge. Cells were Gram-negative, motile, non-sporulating, straight to curved rods with one polar flagellum. The isolate had phenotypic traits of the genus Bosea, including cellular fatty acid and substrate utilization profiles. Physiological charact(...)

Zymography of Monophenolase and o-Diphenolase Activities of Polyphenol Oxidase
DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J
A new procedure for the zymography of monophenolase and o-diphenolase activities of polyphenol oxidase (PPO), and peroxidase (POX) is proposed using a highly sensitive, chromogenic nucleophile 3-methyl-2-benzothiazolinone hydrazone (MBTH), which traps quinones. The procedure allowed the distinction between PPO isoenzymes from sorghum and mushr(...)

Comparison of the content of phenolic compounds, polyphenol oxidase and peroxidase in grains of fifty sorghum varieties
140. DICKO Mamoudou. H., HILHORST, R., GRUPPEN, H., TRAORE, A. S., LAANE, C., van BERKEL, W. J. H. and VORAGEN, A. G. J.
Analysis of fifty sorghum [Sorghum bicolor (L.) Moench] varieties used in Burkina Faso showed that they have different contents of phenolic compounds, peroxidase (POX), and polyphenol oxidase (PPO). Most of the varieties (82%) had a tannin content less than 0.25% (w/w). POX specific activity was higher than the monophenolase and o-diphenolase(...)

Polysaccharide hydrolases from Boscia senegalensis: purification and characterization of endo-1,3-beta-glucanase
DICKO Mamoudou. H., Searle-van LEEUWEN, HILHORST, R., TRAORE, A. S. and Beldman, G.
The leaves of Boscia senegalensis are traditionally used in West Africa in cereal protection against pathogens, pharmacologic applications, and food processing. Activities of a-amylase, b-amylase, exo-(1®3, 1®4)-b-Dglucanase, and endo-(1®3)-b-D-glucanase were detected in these leaves. The endo-(1®3)-b-D-glucanase (EC 3.2.1.39) was purified 203(...)

Extraction, partial purification and characterization of beta-amylase from Gladiolus klattianus
DICKO Mamoudou. H., Searle-van LEEUWEN, HILHORST, R. and TRAORE, A. S.
The bulbs of Gladiolus klattianus are used in Burkina Faso in food processing. Activities of a-amylase and b-amylase were reported within those bulbs for the ®rst time. The puri®cation of the b-amylase involved bu€er extraction, ammonium sulfate precipitation and gel filtration chromatography. The enzyme was puri®ed 47 fold with 75% yield, giv(...)

A strictly anaerobic, gram-negative bacterium was isolated from rice field soils by using lactate as a sole
carbon and energy source. The cells were non-spore-forming, motile, curved rods. Optimal growth occurred
at 35°C and pH 6.8. No NaCl requirement was observed. Vitamins were required for growth. Our isolate,

The nutritional status of meat is tarnished by its association with the induced cooking contaminants. The aim of this study was to assess the heterocyclic aromatic amines profile and contents in processed chicken in Burkina Faso. Eight polar and apolar heterocyclic aromatic amines (HAAs) including 2-mino-3-methylimidazo[4,5-f]quinolone (IQ), 3(...)
