Cottonseed peptone is widely used in microbiology and biotechnology as a nutrient source for the cultivation of microorganisms. It serves as an excellent protein supplement in culture media, promoting the growth of bacteria, yeast, and fungi. Its rich amino acid profile makes it particularly suitable for industrial fermentation processes, such as the production of enzymes, antibiotics, and other bioactive compounds. Additionally, cottonseed peptone is utilized in research laboratories for studying microbial physiology and optimizing growth conditions. Its cost-effectiveness and consistent quality make it a preferred choice in large-scale bioproduction and diagnostic applications.
