Description

Application

A. C. Broth is recommended to cultivate a wide variety of microorganisms and may be used as an unofficial sterility test medium.

Preparation Note

Suspend 34.2 grams in 1000 ml of distilled water and heat to boiling to dissolve the medium completely. Distribute in tubes or bottles to give the desired depth. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes. If the medium is not used on the same day, it is advisable to drive off dissolved gases by boiling or steaming in the autoclave & cool without agitation.

The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
