Originally formulated by Zobell, Marine Agar (also known as Zobell Marine Agar 2216) contains all the nutrients and minerals required by marine flora. Bacteriological Peptone and Yeast Extract serve as the primary sources of nitrogen, vitamins, amino acids, and minerals. The high mineral content, achieved through a complex blend of salts including Sodium Chloride, Magnesium Chloride, Sodium Sulfate, and Calcium Chloride, replicates the osmotic pressure and ionic strength of natural seawater. This specific mineral balance is crucial, as many marine bacteria are halophilic and require these salts for metabolic activity and cell wall stability. The medium is widely used for the microbiological analysis of seawater, marine sediments, and seafood products.
Advantages
- Optimized for Marine Life: Specifically balanced to support the growth of species that fail to develop on standard laboratory media like Nutrient Agar.
- High Sensitivity: Capable of recovering diverse heterotrophic marine bacteria from environmental samples with high efficiency.
- Standard Research Tool: The world-standard formulation for marine microbiology research and environmental monitoring.
- Mineral Rich: Provides essential trace elements (Strontium, Boric Acid, Fluoride, Silica) that are vital for the enzymatic processes of marine microbes.
- Excellent Colony Visualization: The clear agar base allows for the easy observation of colony morphology and pigmentation.
