Lactobacillus delbrueckii subsp. cus (Lactobacillus cus) LB-G40

Strains introduction

Lactobacillus delbrueckii subsp. cus (L. cus), one of the three subspecies of L. delbrueckii, is a facultatively anaerobic, non-motile and non-spore-forming, rod-shaped member of Lactic Acid Bacteria. It is regarded as aciduric or acidophilic, since it requires a low pH (around 5.4~4.6) to grow effectively. The bacterium has complex nutritional requirements. L. cus acts synergistically with Streptococcus thermophilus as thermophilic starter cultures in the manufacturing of yoghurt. At an optimal temperature of approximately 42℃, these cultures grow fast and acidify quickly with desired organoleptic properties. L. cus and S. thermophilus work in synergy, with L. cus producing amino acids from milk proteins, which are then used by S. thermophilus. Both species produce lactic acid, which gives yoghurt its tart flavor and acts as a preservative. The resulting decrease in pH also partially coagulates the milk proteins, such as casein, resulting in yogurt's thickness. While fermenting milk, L. cus produces acetaldehyde, one of the main yogurt aroma components. Some strains of L. cus also produce bacteriocins, which have been shown to kill undesired bacteria in vitro. L. cus and S. thermophilus are not inhabitant in the human being gut, but due to their metabolism can produce the beneficial ingredients to support the human GI tract and already for hundreds years safe application history, hence it is also now popular to be regarded as the probiotic range.
