PROCEDURE The test might be performed both in 5 unique containers if adequate quantity of product is accessible in Each and every container along with the product or service container is usually entered aseptically (i.e., needle and syringe through an elastomeric rubber stopper), or in five sterile, capped bacteriological containers of appropriate dimension into which a ample volume of product or service has long been transferred. Inoculate Each individual container with one of many ready and standardized inoculum, and blend.
Refrigerate the suspension if It's not necessarily used within just two several hours.] Figure out the quantity of cfu for every mL in Every suspension, utilizing the circumstances of media and microbial recovery incubation situations shown in Table 2 to substantiate the initial cfu for every mL estimate. This benefit serves to calibrate the size of inoculum used in the test. The bacterial and yeast suspensions are to be used in just 24 several hours of harvest, but the fungal planning might be stored less than refrigeration for as many as seven days.
11. Test strains need to be inoculated separately using a variety of micro-organisms similar to not a lot more than one hundred CFU, could you explain if Which means only the precise micro-organism less than detection in the test method is inoculated into the growth medium or if Each and every of your four microorganisms are extra independently to the growth medium for every of the specific test methods?
