Lactobacillus delbrueckii

What is Lactobacillus Delbrueckii?

Lactobacillus delbrueckii (L. delbrueckii) is a species bacteria belonging to the Lactobacillaceae family and is naturally found within the human gut. It is a thermophilic probiotic meaning that it thrives at higher temperatures and is ideal for surviving industrial food processing, such as in fermented dairy (yogurt) and bakery products. There are various benefits associated with L. delbrueckii making it a key contributor to the maintenance of good health.

Health Benefits:

Supports Digestive Health

L. delbrueckii can provide digestive health support by supporting the maintenance of a healthy gut microbiota through the production of lactic acid which lowers the pH of the gut making it less habitable for harmful pathogens. Moreover, L. delbrueckii is believed to help maintain intestinal barrier integrity which also helps to protect the body from pathogens. Through these benefits, L. delbrueckii may help alleviate symptoms of digestive discomfort, particularly those linked to inflammation such as cramping and irregular bowel movements.

Boosts Immune System

Research indicates that L. delbrueckii may boost immune system function. For instance, one study found that oral supplementation with a subspecies of L. delbrueckii was highly beneficial for the immune system of elderly individuals, and led to an increase in Natural Killer cells, an increase in T cell subsets and decreased concentrations of the pro-inflammatory cytokine IL-8. Gut health and immune system function are deeply connected and so the immune boosting properties of L. delbrueckii may in part be due to the probiotic's positive effects on the digestive system.

Typical Use:

L. delbrueckii is primarily used as a starter culture for the production of fermented products such as yogurt and cheese due to its production of lactic acid which lowers pH and coagulates milk. Beyond this, the various health benefits of L. delbrueckii has led to it being increasingly used in probiotic supplements, both in single strain and multi-strain formulations alongside other probiotics.
