Enterococcus/ Pediococcus spp.

The culture media products from Ensenmi offer distinct advantages in the development and application of Enterococcus and Pediococcus spp. fermentation. 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 Enterococcus and Pediococcus spp. for different target products, their nitrogen requirements, and the key advantages of Ensenmi fermentation culture media products.

Fermentation Duration for Different Target Products

Enterococcus includes Enterococcus faecalis and Enterococcus faecium. The fermentation products from Enterococcus and Pediococcus spp. are mainly used in probiotics, functional metabolites, cell-based preparations, and selected bioactive compounds. Typical fermentation durations are as follows:

Probiotic / live powder production: 18-36 h

Postbiotic production: 24-48 h

Bacteriocin- antimicrobial peptide production: 18-30 h

 
When producing the above target products by fermentation, the overall fermentation cycle is typically 1-2 days. This requires a rapid and reliable nitrogen supply, making our yeast extract products an ideal nitrogen source supplement for these applications.

Nitrogen Requirements of Enterococcus and Pediococcus spp.

For probiotic production, the goal is to obtain a high viable cell count with strong survival, which requires an adequate supply of high-quality nitrogen sources.

For bacteriocin production, a sufficient amount of high-quality nitrogen is needed in the early and middle stages to support biomass accumulation, followed by efficient expression to enhance antimicrobial peptide yield.

For postbiotic production, the target is not live cells, but rather the culture supernatant, metabolites, cell lysates, and functional components generated during fermentation. In this case, a suitable high-quality nitrogen source can guide the cells toward the production of specific metabolites rather than simply maximizing biomass.

Advantages of Ensenmi Culture Media Products

For probiotic production, Ensenmi yeast extract supports fast fermentation initiation and a short lag phase. Its rich B vitamins help promote carbohydrate metabolism, amino acid metabolism, and energy generation, accelerating cell growth. In addition, its nucleotides support DNA/RNA synthesis and rapid cell proliferation, further reducing the lag phase.

For bacteriocin production, the B vitamins in Ensenmi yeast extract support protein synthesis, energy supply, and product expression, thereby promoting bacteriocin formation. The nucleotides also help reduce the metabolic burden of biosynthesis, improving production efficiency and yield.

For postbiotic production, the B vitamins in Ensenmi yeast extract help optimize metabolic flux and enhance metabolic activity, supporting the formation of functional compounds. The nucleotides further strengthen metabolic activity and promote the accumulation of functional ingredients in the culture supernatant.
