Antibiotic

The culture media products from Ensenmi offer distinct advantages in the development and application of Antibiotic production. We can tailor specific fermentation culture media products to meet customer needs by considering differences in strains and fermentation processes. Below, we summarize the fermentation durations of different Antibiotic production, their nitrogen requirements, and the key advantages of Ensenmi fermentation culture media products.

Fermentation Duration for Different Antibiotic

Antibiotics are mostly secondary metabolites, so their fermentation time is usually longer than that of ordinary fermentation products. Approximate fermentation durations for different types of antibiotics are listed below:

Penicillin: about 5-7 days

Tetracyclines: about 5-8 days

Chlortetracycline: about 5-8 days

Gentamicin: about 4-6 days

Streptomycin: about 4-7 days

Some macrolides: about 5-8 days

This means antibiotic fermentation requires a continuous supply of nitrogen sources. Considering cost, many factories choose inactive yeast powder as the nitrogen source.

Nitrogen Requirements of Microalgae

In industrial antibiotic fermentation, sufficient nitrogen is needed in the early stage to support cell growth. Organic nitrogen sources can provide amino acids, peptides, vitamins, and growth factors, thereby accelerating fermentation. During the product synthesis stage, however, nitrogen levels in the fermenter must be controlled, because excessive nitrogen often inhibits secondary metabolism and causes the cells to favor growth rather than antibiotic production.

Therefore, most processes use fed-batch feeding: relatively abundant nitrogen is supplied in the early stage, and the feed rate is slowed later to control the concentration of available nitrogen. In processes without fed-batch feeding, inactive yeast powder is often used as the organic nitrogen source. This not only reduces production cost, but also provides a continuous and stable nitrogen supply.

Why Choose Ensenmi Culture Media Products?

The vitamin B complex and nucleotides in Ensenmi fermentation media products can provide antibiotic-producing microorganisms with essential coenzyme precursors and raw materials for nucleic acid synthesis. This helps promote cell growth, enhance metabolic activity, improve the initiation of secondary metabolism, and increase antibiotic yield and batch-to-batch consistency.
