Does Lactococcus lactis have a capsule?

The exopolysaccharide (EPS) capsule-forming strain SMQ-461 of Lactococcus lactis subsp. cremoris, isolated from raw milk, produces EPS with an apparent molecular mass of >1.6 × 106 Da.

Accordingly, does lactococcus lactis produce gas?

Lactic acid bacteria that produce CO2 are used in the dairy industry to favor the formation of openings in some types of cheeses. This work was undertaken to characterize the gas producing activity of Lactococcus lactis strains that over-produce CO2 as a result of their attenuated lactate dehydrogenase activity. What is Streptococcus Cremoris? cremoris, as now known, is a rather dis- tinct type of lactic acid streptococcus, the species has not been so clearly defined as is necessary. The differences between S. cremoris and S. lactis appear to be relative or quantitative ones rather than definitive.

What is the difference between Streptococcus and Lactococcus?

Lactococcus is a genus of lactic acid bacteria that were formerly included in the genus Streptococcus Group N1. They are known as homofermenters meaning that they produce a single product, lactic acid in this case, as the major or only product of glucose fermentation. Does L. lactis ferment mannitol? Mannitol, a low calorie sweetener and antioxidant, is believed to have several health- promoting and protective properties. In situ mannitol production by Lactococcus lactis, a lactic acid bacterium extensively used in the dairy industry, may therefore result in fermented food products with extra value.

Is Lactococcus lactis a lactic acid bacteria?

Introduction. Lactococcus lactis is a non-motile, non-spore-forming, low G+C, Gram-positive lactic acid bacterium. It is used as a starter culture in the production of a wide range of fermented dairy products where it contributes to food preservation, flavor and texture formation (Smid and Kleerebezem, 2014).
