    Abstract: The objective of this study is to improve the preparation of a biosorbent from the cocoa pod shell by an experimental plan. The shells underwent drying and grinding followed by chemical impregnation with sodium hypochlorite. The process was optimized based on the analysis of the methylene blue index as a function of four factors: the drying tempera... Show More

    Abstract: The objective of this work is to characterize and determine the fatty acid composition of Pellonula leonensis oil from the Congo River and Nianga Lake, in order to determine the bioavailability of docosahexaenoic (DHA) and eicosapentaenoic (EPA) acids. Pellonula leonensis fish were caught in the Congo River in southern Congo–Brazzaville in the loca... Show More
