Physicochemical properties of gum Arabic are greatly affected by bacteria invasion before industrial processing. In this study, laboratory procedures as well as biochemical tests were used to assess the effect of some isolated bacterial species on the physicochemical aspects and main components of Acacia senegal var. Senegal gum Arabic. Degradation effects on the molecular weight of gum Arabic main components were remarkably affected in comparison to control. The arabinogalactan protein (AGP) was increased to six folds (from 3.80×106 to 22.69×106) by Penicllium notatum, and to three folds (11.03×106) by Corynebacterium xerosis, and to (7.08×106) by Fusarium moniliforme. Conversely, the AGP was decreased by Aspergillus niger from 3.80×106 to 1.36×106, whereas the bulk of the material corresponding to the protein-deficient arabinogalactan (AG) and galactoprotein (GP) component was decreased from 3.45×105 to 2.71×105. The results indicate that microorganisms have great impact on gum Arabic quality.
