TL;DR: Gum Arabic (Acacia senegal ) from Kordofan (Central Sudan) and Damazin (Blue Nile, Western Sudan) were used in this paper to study physicochemical properties of gum samples.
Abstract: Gum Arabic (Acacia senegal ) from Kordofan (Central Sudan) and Damazin (Blue Nile, Western Sudan) were used in this study. Physicochemical properties of gum samples were studied (moisture, ash, nitrogen, total soluble fiber, specific rotation, relative viscosity, refractive index and pH). Results show significant differences in moisture content, protein content and relative viscosity between Kordofan and Damazin gums. Damazin gum contained higher protein (3%) and characterized by higher viscosity (24.81) compared to Kordofan gum. Stability of Acacia gum emulsion in regard to type of refined oil (sesame, groundnut, cotton seed, sunflower and corn), temperature, stirring time, concentration and gum grade was also investigated. Results revealed that emulsion stability is significantly affected by the type of oil used. Cotton seed oil gave the most stable emulsion while groundnut resulted in the lowest stable emulsion. Increase in the length of the stirring time is significantly increased stability of the emulsion. Also emulsion stability was affected by gum grades. Other factors of concentration and temperature did not significantly influence emulsion stability.

TL;DR: In this paper, pre-and post-exposure characterization of copper thin films on germanium substrates were done by Auger electron spectroscopy and x-ray photoelectron spectrography.
Abstract: Thin films (3.4 nm) of copper on germanium substrates were exposed to 10% gum arabic aqueous solution, 1% bacterial culture supernatant (BCS) (aqueous and simulated sea water solutions) and 0.5% Pseudomonas atlantica exopolymer (aqueous and simulated sea water solutions). Pre- and post-exposure characterization were done by Auger electron spectroscopy and x-ray photoelectron spectroscopy. Ancillary graphite furnace atomic absorption spectroscopy was used to monitor the removal process of the copper thin film from the germanium substrate. Results indicate that the copper was oxidized by the gum arabic and BCS, and some was removed from the Cu/Ge interface by all three polymers and incorporated into the polymer matrix. Thus, biocorrosion of copper was exhibited by the gum arabic, BCS and Pseudomonas atlantica exopolymer.
