Nitrogen Utilization Medium – Custom Base for Microbial Nitrogen Metabolism Studies (250g)
Defined Nitrogen Utilization Medium for Microbial Metabolic Profiling
This glucose-based minimal medium (10.0g/L dextrose) provides a standardized platform for evaluating microbial nitrogen source utilization. With balanced phosphate buffer (pH 7.2±0.2) and essential minerals, it enables precise comparison of different nitrogen sources’ effects on microbial growth kinetics and metabolic pathways.
Key Applications:
🔬 Nitrogen Metabolism Research: Study microbial preferences for organic/inorganic N sources
🧫 Industrial Strain Development: Optimize nitrogen utilization in fermentation processes
🧪 Environmental Microbiology: Characterize soil/water microbial N cycling
Technical Highlights:
✅ Nitrogen-Free Base: Contains no interfering nitrogen compounds
✅ Energy-Rich: 10.0g/L glucose supports growth during N source testing
✅ pH-Stabilized: Phosphate buffer maintains 7.2±0.2 through growth phases
✅ Trace Minerals: 0.02g/L FeSO₄ for metalloenzyme synthesis
