Alternatively, the inventory culture organisms might be grown in a suitable liquid medium (i.e., Soybean–Casein Digest Broth or Sabouraud Dextrose Broth) as well as the cells harvested by centrifugation, then washed and resuspended in sterile saline TS to acquire a microbial count of about 1 × 108 cfu per mL. [Notice—The estimate of inoculum concentration can be done by turbidimetric measurements to the problem microorganisms.), inoculating Each individual plate with a small number (not a lot more than a hundred cfu) of the right microorganism. Incubate at the desired temperature for any stretch of time inside the array specified in the test. Colonies are similar in overall look and sign reactions to Individuals Earlier received by using a Beforehand tested and accredited batch of medium.
