Alternatively, the stock society organisms could be developed in an appropriate liquid medium (i.e., Soybean–Casein Digest Broth or Sabouraud Dextrose Broth) plus the cells harvested by centrifugation, then washed and resuspended in sterile saline TS to acquire a microbial count of about one × 108 cfu for each mL. [NOTE—The estimate of inoculum focus could possibly be performed by turbidimetric measurements with the obstacle microorganisms.
One of several key techniques in preventing the Peter Principle is fostering self-consciousness among staff members.
