Frequently Asked Questions
โ
What is beef extract powder used for in microbiology?
Beef extract powder is widely used as a nitrogen source in culture media for microbial growth. It compensates for the nutritional deficiencies of peptone by supplying peptides, amino acids, and natural growth factors that support efficient microbial cultivation and fermentation.
โ
Can the physicochemical specifications be customized?
Yes. While the listed physicochemical index represents the general specification, we can customize the product parameters โ including nitrogen content, moisture, ash level, and pH โ according to specific customer requirements.
โ
How should beef extract powder be prepared before use?
The product must be fully dissolved in the appropriate solvent and sterilized before use. This ensures the integrity of the culture medium and prevents contamination during microbial cultivation.
โ
What packaging options are available?
Beef extract powder is available in compound paper bags (25 kg/bag), cardboard buckets for bulk use, and 250 g plastic bottles for reagent-grade applications. Custom packaging sizes and OEM packaging are also supported upon request.
โ
What is the minimum total nitrogen content in this product?
The minimum total nitrogen content (on dry matter basis) is ≥14.0%, and the amino nitrogen content is ≥2.5%. These values ensure the product provides sufficient nutritional support for microbial growth and fermentation processes.
โ
Is this product suitable for large-scale industrial fermentation?
Yes. Beef extract powder is suitable for both biological laboratory applications and large-scale microbial fermentation industries. Its rich composition of peptides, amino acids, and growth factors makes it a high-grade raw material for optimizing cultivation efficiency and strain activity.
