To be used as one of many bases for measuring the sanitation volume of The entire technique of drug generation
Dilute parts of each from the cultures working with Buffered Sodium Chloride-Peptone Answer, or Phosphate Buffer to prepare test suspensions containing about fifty to two hundred feasible microorganisms per mL. Progress-selling attributes are tested by inoculating 1 mL of every microorganism into each medium. The test media are satisfactory if apparent evidence of expansion appears in all inoculated media immediately after incubation at indicated temperature for five days.
