Sudano-Sahelian domain is the poorest in biodiversity because of climate which unfavourable compared to equatorial climate. The unsustainable agricultural practices associated with this climatic roughness are among main factors habitat destruction, hence destruction phytogeographic environment. In order valorize and conserve sudano-sahelian plant resources, a study was carried out seasonal agro...

A preliminary experimental study was carried out to examine the ability of a chemically modified Acacia spp. to resist biodegradation. The modifications of Acacia mangium and Acacia hybrid were carried out by propionic anhydride and succinic anhydride in the presence of sodium formate as a catalyst. The treated samples were found resistant to microbial attack, while the untreated ones were dama...

Removal of blood plasma by plasmapheresis from dogs made hypoproteinemic by injections of gum acacia over long periods of time, has resulted in the removal of more gum acacia than was originally present in the plasma. Gum acacia injections had been discontinued previous to the start of the experiments, and hence it must be concluded that the excess amounts of acacia were derived from deposits i...
