Streptococcus is a bacteria that is characteristic grouping of chains resembles a string of beads. Streptococcus lactis is used in commercial starters for the production of butter, cultured buttermilk and certain cheeses.
The oxidase test result for Lactococcus lactis ssp lactis is negative. This bacterium lacks the enzyme cytochrome c oxidase that is needed to produce a positive result in the oxidase test.
Lactobacillus lactis is a rod shape bacterium
Lactococcus lactis is commonly found in dairy products such as milk and cheese, where it plays a role in fermentation. It is also present in the digestive systems of some mammals, including cows and humans.
Yes is negative
Glace lactis.
Lactococcus lactis is a spherical-shaped bacterium that typically occurs in pairs or chains. It is a Gram-positive bacterium that does not form spores and is non-motile. The arrangement of L. lactis can vary depending on growth conditions and phase of growth.
Lactococcus lactis is a bacteria commonly used in the production of dairy products like cheese and yogurt, while Enterococcus faecalis is a bacteria that is often found in the intestines of animals and humans. L. lactis is generally considered safe, whereas E. faecalis can be a pathogen and cause infections in humans, particularly in hospital settings. Additionally, L. lactis is a lactic acid bacterium used in fermentation processes, while E. faecalis is a member of the Enterococcus genus known for its ability to survive in harsh environments.
Lactococcus lactis subspecies hordniae is commonly found in dairy environments, such as in raw milk and dairy products like cheese and yogurt. It thrives in the acidic conditions of these fermented products, playing a key role in their production.

It is used in souring dairy products, so it is mainly used in cheese making.
There are no good or bad bacteria. They are doing the jobs that their DNA has programed them to do. As far as B. lactis is concerned, we use it to make cheeses.It also has been associated with a disease in newborns. Sometimes bacteria cause problems if they are in the wrong place at the wrong time.
E.coli shows positive result for catalase test..staphylococcus aureus and serratia marcescens too..pseudomonas and klebsiella does not give any vigorous bubbling therefore, it shows negative result
