Summary: The adsorption of Acacia gums onto latex particles is a complex mechanism influenced by the charges and hydration status of the gums, as well as the protein moiety and electrostatic interactions. The structural accessibility and viscoelastic properties of the gums also play a crucial role in the adsorption process.

Summary: This study thoroughly investigated the adsorption of five different hyperbranched arabinogalactan-protein (AGP) fractions from Acacia senegal gum at the solid-liquid interface using various techniques. The results showed that the adsorption capacity was influenced by the protein moiety and high-molecular-weight AGP content, as well as other parameters such as protein structural accessibility and molecular weight distribution.

Summary: The study showed that Acacia senegal (AS) gum aqueous extract (ASE) has potent antioxidant and anti-inflammatory effects, alleviating oxidative and necroinflammatory stress induced by CCl4. ASE improved toxicity in liver, lung, brain, and spleen by regulating the ROS/NF-kappa B signaling pathway and enhancing antioxidant capacity in these organs.

Summary: Acacia Senegal Gum hydrogel (HASG) with dimensions less than 50 μm were chemically modified with diethylenetriamine (D-amine) to remove negatively charged metal ions, such as chromate (Cr(III)), dichromate (Cr(VI)), and arsenate (As(V)) from aqueous media. The modified hydrogels (m-HASG) exhibited a positively charged surface and showed high adsorption efficiency towards the targeted analytes. The adsorption isotherms indicated that the modified Freundlich isotherm provided the best fit for the pollutants, with a maximum adsorption capacity of 217-271 mg g-1. In conclusion, m-HASG is a promising material for environmental applications in removing toxic metal ions.

Summary: The study evaluated the effects of Gum Arabic on the performance, immune system, visceral organs, and histological changes in the ileum, liver, and kidneys of broiler chickens. The results showed that Gum Arabic improved growth performance and feed conversion ratio, had no effect on the relative weight of lymphoid and visceral organs, and showed potential to decrease serum uric acid, creatinine, and alanine aminotransferase levels. Histological changes in the intestine, liver, and kidneys also improved. These findings suggest that Gum Arabic may be used as a natural prebiotic to improve broiler chicken performance and intestinal, liver, and kidney health.

Summary: The study aimed to assess the changes in hormonal and metabolic profiles in PCOS patients after the ingestion of gum arabic. The results showed that continuous ingestion of gum arabic for eight weeks can decrease luteinizing hormone and LH/FSH ratio, and improve metabolic profiles by reducing cholesterol levels.

Summary: The study found that ingestion of gum arabic for eight weeks resulted in a significant decrease in luteinizing hormone level and FSH/LH ratio, along with an improvement in the metabolic profile by reducing cholesterol level in PCOS patients. However, there were no significant changes observed in testosterone, insulin, or HBA1c levels.

Summary: This study evaluated the effects of provenance on seed morphology, germination characteristics, and seedling growth performance of Acacia senegal variety senegal. The results showed significant differences in seed morphological and germination characteristics among provenances, but no difference in seedling growth parameters. Provenances differed significantly in terms of total germination, days required for 50% germination, and germination speed. The findings of this study are important for selecting suitable seed sources for gum production in afforestation and reforestation programs.

Summary: This study investigated the molecular mechanism of seed dormancy breaking at cold temperatures in Fritillaria taipaiensis and explored the genetic regulation of germination initiated by exposure to cold temperature. The results showed that stratification at 4 degrees Celsius induced an upregulation of gene expression involved in gibberellic acid and auxin biosynthesis, promoting embryo development and seed germination. This study provides valuable insights into the regulation of seed germination in F. taipaiensis and other non-model plant species.

Summary: Adsorption isotherms of pectin from citrus peel, apple pomace, and creeping fig seeds onto wheat starch granules were determined, showing that pectin molecules penetrated into the granules and reduced starch leaching. The gelatinization process was slightly affected by the presence and degree of pectin interpenetration. The viscosity of starch-pectin dispersions increased with pectin concentration, while the final viscosity of starch pastes decreased with pectin molar mass.

Summary: The objective of this study was to identify native bacterial strains that can alleviate abiotic stress caused by herbicide application and promote plant growth. The researchers isolated bacteria from the rhizosphere of field-grown alfalfa and screened them for various growth-promoting traits. Serratia rubidaea, Pseudomonas putida, and Serratia sp. were found to have the highest potential, with S. rubidaea being the only strain capable of producing auxin. Inoculation of these bacterial strains in alfalfa plants showed beneficial effects in terms of growth and development, especially when combined with Sinorhizobium meliloti.
