To diagnose Enterococcus faecalis:
(Facultative anaerobic)
First, do the Gram stain: Gram positive cocci in chains
catalase test: negative
PYR disc: positive
From what I've found... Lactococcus lactis won't grow on a 6.5% plate while enterococcus faecalis will. Hope that helps!
-VE
in the broth they will be packed close together and more spread out in the slant
No it doesn't. Entercocci and members of the streptococcus group can.

Lactococcus lactis is used in the production of buttermilk and cheese. Lactococcus lactis is what is known as a gram positive bacteria.

Yes is negative

There may be a variety of molds that grow on milk. The usual ones are lactic acid bacteria, which includes lactococcus lactis and lactobacillus bulgaricus.

The streptococci occur in pairs or chains, and some species are pathogenic in humans. Streptococcal infections include strep throat, scarlet fever, tonsillitis, erysipelas, puerperal fever and some pneumonias. It is used in dairy products to create cheese, and it is related to the bacterium previously mentioned.

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
Lactobacillus lactis is a rod shape bacterium
