Common Name: Nutrient Agar
English name: Nutrient Agar
Used for colony counting in the inspection of food and other items.
Culture medium is a mixed nutritional product prepared by artificial methods, specifically for microbial cultivation, separation, identification, research, and preservation. The peptone and beef extract contained in nutrient agar provide nitrogen, vitamins, amino acids, and carbon sources; Sodium chloride can maintain a balanced osmotic pressure; Agar is a coagulant for culture medium.
Peptone, beef extract powder, sodium chloride, agar powder and other culture medium materials are milled and packaged.
After pre-treatment according to GB standards, the samples were inoculated into a culture medium at 30-35 ℃ for 24-48 hours, and the results were observed.
Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa all grew well.
1. This culture medium is only used for scientific research and research
2. The collected specimens must be inoculated and cultured as soon as possible to ensure accurate results.
3. The specimens used and their cultivation waste should be considered as potentially infectious substances and should be disposed of in accordance with the operating standards of infectious disease laboratories.
4~30 ℃, stored away from light.
【Period of validity】
The validity period is 3 years.
