Ammonium Sulfate: Nitrogen Source and Fermentation Nutrient
Ammonium sulfate is an inorganic salt widely used as a nitrogen source in fermentation media, agricultural fertilizers, and select industrial processes. In pharmaceutical and biotechnology contexts, it serves as a precipitating agent for protein purification (salting-out) and as a nutrient supplement in microbial fermentation. Its high water solubility and stable crystalline form make it a practical and cost-effective nitrogen source.

Formulation Applications
In biopharmaceutical manufacturing, ammonium sulfate is the standard reagent for fractional protein precipitation due to its high solubility and stabilizing effect on protein structure. It is used at varying saturation levels (typically 20–80%) to selectively precipitate target proteins. In fermentation, it provides both nitrogen and sulfur to microbial cultures. In the agrochemical sector, it is a widely used straight nitrogen fertilizer (21% N, 24% S) and serves as an adjuvant in herbicide spray solutions to improve efficacy in hard-water conditions.
