Alternatively, the inventory lifestyle organisms could be developed in a suitable liquid medium (i.e., Soybean&#one hundred fifty;Casein Digest Broth or Sabouraud Dextrose Broth) as well as the cells harvested by centrifugation, then washed and resuspended in sterile saline TS to obtain a microbial count of about one × 108 cfu for each mL. [Observe—The estimate of inoculum focus can be performed by turbidimetric measurements for the challenge microorganisms.
Resulting from pour plates demanding lengthier incubation intervals and also the variability of colony sizes, the usage of a backlit colony counter is suggested.
