Phd Thesis (Doctorat De Spécialité): Université De Ouagadougou, 1999. Dr. Mamoudou H. Dicko. Purification Et Propriétés Physico-Chimiques Des Enzymes De Curculigo Pilosa, Gladiolus Klattianus Et Boscia Senegalensis Catalysant L'Hydrolyse Des Polysaccharides (Amidon Et Béta-Glucanes), Mamoudou H.

Pr. Mamoudou H. DICKO, PhD
The objective of this study was the research of novel and inexpensive sources of polysaccharides degrading enzymes such as amylases and glucanases from local plants in order to justify their biotechnological applications. The isolation of two l3-amylases and an endo-1,3-ß-D-glucanase was reached using common protein purification methods such as buffer extraction, ammonium sulfate fractionation, ionexchange and gel filtration chromatographies. The methods used were simple and easily reproducible, suggesting the possibilfty of large-scale production. ln the crude extract of Curculigo pilosa tuber, only ß-amylase was detected as starch degrading enzyme and its activity was approximately 282 Uig of fresh material. The …

Institutional Changes And Discretionary Value For Property Rights In Drylands’ Farming Of The Sudan, Professor Issam A.W. Mohamed
Professor Issam A.W. Mohamed
Research on land tenure and use control and the socioeconomic sets of regulations in the agricultural rainfed sub sector of Sudan, come to focus for many reasons. Anthropogenic pressure, expanding animal population and migration led to accelerated impacts on both the ecological systems and land yields. Conflicts between governmental regulations and indigenous rules contribute to generate inconsistencies on who have the right to till the land and hence own it. With such transformation logically, more intensive commercial farming took place and land intake exponentially increased. Private or collective property rights of land are procured through traditional tenure, prescription, settlement or …
