Description

Soybean-Casein Digest Agar: The Ideal Medium for Microbial Cultivation

Soybean-Casein Digest Agar serves as a highly effective medium for isolating and cultivating both nonfastidious and fastidious microorganisms. This nutrient-rich formulation supports diverse microbial growth, making it a staple in microbiology laboratories.

Key Features

  • Nutritional Composition: The unique blend of enzymatic digests of casein and soybean meal provides essential organic nitrogen, including amino acids and longer-chained peptides. These nutrients play a crucial role in promoting optimal microbial development.
  • Optimal pH Balance: With a final pH of 7.3 ± 0.2 at 25°C, Soybean-Casein Digest Agar maintains a stable environment that fosters robust microbial activity.
  • Versatile Usage: Researchers often use this medium to support a wide variety of microorganisms. However, it does not suit anaerobic bacteria.

Preparation Instructions

To prepare Soybean-Casein Digest Agar, follow these steps:

  1. Suspend 40.0 g of the medium in one liter of deionized or distilled water.
  2. Mix well and heat with frequent agitation.
  3. Boil for one minute, then dispense into tubes or flasks.
  4. Sterilize in the autoclave at 121°C (15 lbs.) for 15 minutes.

This straightforward process makes the medium convenient for laboratory use.

Storage Guidelines

For optimal performance, store the dehydrated medium in a tightly capped original container at temperatures ranging from 5-30°C. Ensure the product is used before its shelf life of three years from the manufacturing date. Additionally, keep prepared medium out of direct light at 2-8°C to maintain quality.

Quality Control Measures

Researchers should carefully observe cultural characteristics after incubating the medium at 25 ± 1°C for 48 hours. This practice ensures the medium meets established performance criteria and effectively supports microbial growth.

Approximate Formula for Soybean-Casein Digest

Ingredients (per liter):

  • Enzymatic Digest of Casein: 15.0 g
  • Enzymatic Digest of Soybean Meal: 5.0 g
  • Sodium Chloride: 5.0 g
  • Agar: 15.0 g

Final pH: 7.3 ± 0.2 at 25°C

Note: Researchers may adjust or supplement the formula as needed to meet specific performance criteria.

In summary, Soybean-Casein Digest Agar stands out as a highly nutritious and reliable medium for microbial research. Its balanced formulation allows for effective microbial isolation and cultivation, making it a trusted choice for researchers seeking consistent results in their experiments.
