Genome sequencing of the Lactobacillus johnsonii bacterium.


Lactobacillus johnsonii (La1), the lactic acid bacteria used in Nestlé’s LC1 range of dairy products, offers consumers myriad health benefits through probiotics. Scientists at NRC have successfully identified the genome sequence of this bacterium.

Big benefits in a small package

The human intestine contains many bacteria, some of these are beneficial and some are not. Probiotics are bacteria that exhibit beneficial effects for digestive health and immunity when consumed. Lactobacillus johnsonii, for example, is a probiotic bacteria that adheres strongly to the gut mucosa, competing with certain pathogens that cause disease, thus preventing the inhabitation of dangerous bacteria in the gastrointestinal system.

Deepening our understanding of probiotics

Nestlé is a leader in probiotic genomics. Sequencing of the La1 genome by Nestlé Research Center scientists is a breakthrough technology. Prior to this discovery, there was little knowledge regarding probiotic function at the molecular level. Sequencing the entire probiotic La1 genome provides researchers valuable insights into the symbiotic relationship of humans and probiotic bacteria.

Pioneers in probiotics

Nestlé has pioneered the development of probiotics and their use in dairy products. Nestlé LC1 yogurt, which contains La1 probiotics, has documented health promoting results and is part of a healthful, balanced diet.
