AATCC BACTERIOSTASIS BROTH (FDA BROTH)

AATCC Bacteriostasis Broth (FDA Broth) is useful for subcultures in phenol coefficient and dilution tests of bacteriostatic, germicidal, sporicidal activity and also as a base for the preparation of AATCC Bacteriostasis Agar. The test cultures of Escherichia coli and Staphylococcus aureus are grown in AATCC Bacteriostasis Broth for 24 hours. 1 ml of this culture is mixed with 150 ml of AATCC Bacteriostasis Agar and poured into the plate. After the agar solidifies, apply a circular sterile test fabric of 28.6 mm diameter onto the plate. Incubate at 35-37?C for 18-24 hours and observe the inhibition of growth around test fabric.

for routine antibacterial testing of antiseptics and disinfectants
