Tryptose Phosphate Broth is used for the cultivation of a wide variety of fastidious microorganisms and is not intended for use in the diagnosis of disease or other conditions in humans. This is a versatile, nutritionally rich buffered glucose broth.
Does LSL broth inhibit the growth of non coliforms?
Inhibits non-coliform from growing. What happens in confirmed test? A loopful of LSL broth from a tube showing gas production is transferred into a tube of BGLB broth to confirm presence of coliforms.
What is BGLB Broth?
BGBLB (Brilliant Green Bile Lactose Broth) contains both ox bile and brilliant green dye, which suppress the growth of gram-positive bacteria as well as many gram-negative bacteria. Coliforms are resistant to these inhibitors. Further, the formation of gas indicates that lactose fermentation is occurring.
