What is the Natural habitat for lactococcus lactis subspecies hordniae?
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.
What is the difference between lactococcus lactis and enterococcus faecalis?
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.
What is the test that separates enterococcus faecalis and lactococcus lactis?
To diagnose Enterococcus faecalis: (Facultative anaerobic) First, do the Gram stain: Gram positive cocci in chains catalase test: negative PYR disc: positive
How does lactococcus lactis appear on nutrient broth culture?
Lactococcus lactis typically appears as small, smooth, white or cream-colored colonies on nutrient broth culture. It is non-motile, non-spore forming, and has a characteristic round or oval shape. Under a microscope, it may appear as individual or pairs of cocci (spherical-shaped cells).
Does lactococcus lactis grow in bile esculin?
Lactococcus lactis is a lactic acid bacteria commonly found in dairy products and does not typically grow in high levels in bile esculin. This medium is mainly used to differentiate enterococci, Streptococcus bovis, and Group D Streptococcus based on their ability to hydrolyze esculin in the presence of bile.
