En Afrique, de nombreuses espèces végétales ne sont pas suffisamment exploitées, malgré leurs valeurs comestibles indéniables. Parmi ces plantes figurent les aubergines amères Solanum anguivi Lam et torvum communément appelées "gnagnan" en Côte d'Ivoire. Les baies légumes-fruits séchées analysées selon des méthodes standard conventionnelles. Le tri phytochimique a révélé que S. contient plus st...

dbstract. mis paper continues the description of an isothermal titration calorimeter already outlined in the previous paper. We have determined its thermal parameters and report here on the performance of the calorimeter and the method of measuring via electrical compensation of the thermal effect. We have also calculated the effective volume of the reaction vessel and the heat of stirring of t...

tiation of true dysentery bacilli from allied organisms described and named three species or groups of species of bacilli which though strongly resembling the true dysentery bacilli were not considered by him as causal agents of dysentery; one of these was Bacterium alkalescens. Andrewes described it as a Gram-negative non-motile bacillus which produced acid but no gas in glucose, maltose, mann...

Six selective media, namely xylose lysine desoxycholate agar (XLD), desoxycholate citrate agar (DCA), desoxycholate citrate lactose saccharose agar (DCLS), Salmonella Shigella agar (SS), bismuth sulphiteagar (BS) and brilliant green agar (BG), were compared for recovering Salmonella from pure cultures using the pour plate method. BS agar was superior to alt-the other agars in supporting growth ...

The presence of glucokinase (GK), a critical enzyme controlling glucose homeostasis and particularly liver glucose utilisation in mammals, has long been a matter of debate in avian species as a number of investigators failed to detect glucokinase activity in livers from the chicken and several other avian species. In this study we cloned a partial GK cDNA from mule duck livers and we measured G...
