Application


  • Isolation and identification of milk-clotting proteases from Prinsepia utilis Royle and its application in cheese processing.: This study utilized ammonium sulfate for the isolation of milk-clotting proteases, which were then applied in cheese processing, enhancing the efficiency and quality of cheese production (Zhang et al., 2024).

  • Diffusion-driven fed-batch fermentation in perforated ring flasks.: The research used ammonium sulfate in fed-batch fermentation processes to enhance microbial growth and product yield, demonstrating its utility in optimizing industrial fermentation techniques (Lüchtrath et al., 2024).

  • Ammonium Sulfate to Modulate Crystallization for High-Performance Rigid and Flexible Perovskite Solar Cells.: This research investigates the role of ammonium sulfate in modulating the crystallization process of perovskite solar cells, significantly improving their performance and stability (Zou et al., 2024).

  • Effectiveness of three nitrification inhibitors on mitigating trace gas emissions from different soil textures under surface and subsurface drip irrigation.: The study utilized ammonium sulfate in combination with nitrification inhibitors to reduce trace gas emissions in agricultural settings, highlighting its environmental benefits (Ribeiro et al., 2024).
