Application
- Isolation and identification of milk-clotting proteases from Prinsepia utilis Royle and its application in cheese processing.: This research highlights the use of ammonium sulfate in precipitating specific enzymes during cheese production, optimizing the isolation of milk-clotting proteases which are crucial for improving cheese yield and quality (Zhang L et al., 2024).
- Diffusion-driven fed-batch fermentation in perforated ring flasks.: Demonstrates an innovative application of ammonium sulfate in fermentation processes, where it serves as a nitrogen source to sustain microbial growth and enhance biotechnological production efficiencies (Lüchtrath C et al., 2024).
- Extraction of Protein and Bioactive Compounds from Mediterranean Red Algae (Sphaerococcus coronopifolius and Gelidium spinosum) Using Various Innovative Pretreatment Strategies.: This study utilizes ammonium sulfate in a salting-out process to efficiently extract valuable proteins and bioactive compounds from red algae, contributing to advancements in nutritional supplements and pharmaceuticals (Dhaouafi J et al., 2024).
