Refrigerate the suspension if it is not applied within just 2 hours.] Decide the volume of cfu per mL in Each and every suspension, utilizing the conditions of media and microbial Restoration incubation times outlined in Table two to verify the Preliminary cfu for each mL estimate. This worth serves to calibrate the dimensions of inoculum Employed in the test. The bacterial and yeast suspensions are to be used in 24 hrs of harvest, although the fungal preparation may very well be saved less than refrigeration for nearly 7 times.

Manager Quality Control is accountable to make sure that procedure and formats are adopted fully as permitted.
