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(...)

Isolation and characterization of Desulfovibrio burkinensis sp. nov. from an African ricefield, and phylogeny of Desulfovibrio alcoholivorans
A. S. Ouattara, B. K. C. Patel, J.-L. Cayol, N. Cuzin, A. S. Traore and J.-L. Garcia
A sulfate-reducing bacterium, strain HDvT (T¯type strain), was isolated from an anoxic ricefield soil. Cells were Gram-negative, non-sporulating curved rods motile by means of a single polar flagellum. Cytochrome c3 and desulfoviridin
were present. In the presence of sulfate, glycerol, 1,2- and 1,3-propanediol, dihydroxyacetone, pyruvate, lac(...)

Characterization of Anaerovibrio burkinabensis sp. nov., a Lactate- Fermenting Bacterium Isolated from Rice Field Soils
ABOUBAKAR S. OUATTARA,' ALFRED S. TRAORE,, AND JEAN-LOUIS GARCIA'"
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,
strain B4BoT (T = type stra(...)

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(...)
