Portfolio: SiliCycle's Probiotic Strains

> back to SiliCycle Probiotics main page

Lactococcus lactis MJC18 and Pediococcus acidilactici UL5 are SiliCycle's exclusive probiotic strains. These common lactic acid bacteria are well documented and characterized, and offer interesting features, including high survival rate in gastro-intestinal environment and very negligible impact on the natural gut microbiota.
But their most distinctive characteristic is that they can produce natural antimicrobial substances called bacteriocins.

Pediococcus acidilactici and Lactococcus lactis: Lactic Acid Bacteria

Pediococcus and Lactococcus are genera of lactic acid bacteria (LAB) commonly found in several human foods such as vegetables, cheese and meat. LAB are Gram+ bacteria that produce lactic acid when fermenting carbohydrates. In fact, LAB actively take part in the process of producing numerous fermented foods, for example in the making of cheese starting from milk or sauerkraut starting from cabbage. Fermented foods produced with LAB show many advantages like their ability to resist better to spoilage, which is due to the acidification caused by the lactic acid production, and their positive impact on human health resulting from a better assimilation of nutrients and vitamin production by LAB.

Pediococcus acidilactici is a species of Pediococcus that is starting more and more to attract interest in the probiotic world. In fact, not only is this species able to produce lactic acid that a direct antagonist effect against some human pathogens, but it is particularly tolerant to very acidic environments (low pH) and oxygen.

Lactococcus lactis, a species of the Lactococcus genus, is one of the most used bacteria in the dairy industry, particularly for cheese production. Lactococcus lactis is a facultative anaerobe microorganism, which means it can develop with or without oxygen, and tolerates highly acidic environments.

 

UL5 and MJC18: Because Strains Matter

Even though the different species of LAB all share some common properties (the main one being their lactic acid production), they have major differences in their metabolism and their ability to act as probiotics is extremely variable. This is no surprise when we know the fact that even different strains of the same species of bacteria (for example, different strains of Pediococcus acidilactici or Lactococcus lactis) can act in a very different way in a given context. As stated in the previous section, this is exactly why it is so important to always make sure that very specific strains of bacteria are used in probiotic products: it is the only way to guarantee the client will truly get the benefits he is looking for.

Pediococcus acidilactici UL5 and Lactococcus lactis MJC18 are two strains that have been isolated and precisely characterized in Laval University. Based on a very solid body of scientific research, these two strains have been selected for their characteristics allowing them to act as very interesting and unique probiotics. Scientific studies have showed that these two strains have a high survival rate in gastro-intestinal environment, that have the ability to colonize the gastro-intestinal tract and that they have a very negligible impact on the natural gut microbiota. But their most distinctive characteristic is that they can produce natural antimicrobial substances called bacteriocins.
