Criblage d’enzymes polysaccharidasiques dans les extraits d’amandes des noyaux de six variétés de mangues (Mangifera indica L.) cultivées à DALOA (Centre Ouest, Côte d’Ivoire)

Résumé

Screening of polysaccharide enzymes in extracts from the seeds of six mango varieties (Mangifera indica L.) cultivated in DALOA (Central West, Côte d'Ivoire)

The objective of this work was to detect the presence of polysaccharidases in kernel almonds of six varieties of mango (Mangifera indica L.) cultivated in the region of DALOA (Côte d'Ivoire) to select new sources of original activities biocatalysts. To achieve this, the analyses were carried out on raw enzymatic extracts made from almonds of the varieties Brooks, Kent, Cameroon, Amélie, Keitt and Zill. Specific activities were identified and compared. The polysaccharidasic activities characterized are successively xylanase, cellulase, amylase and inulinasic activities. The Brooks variety has the highest xylanase and cellulase specific activity values. The varieties Kent, Cameroun, Amélie and Zill have low values of polysaccharidasic activities. Comparing all values of specific activities, the Keitt variety has average specific amylase and inuline activity. The study shows that these almonds have biomolecules that could be important enzyme tools in the development of biotechnology for the food industry, health, nutrition and many other fields.
