If a lot more than 5 organisms outlined in Desk-I then conduct the Growth Promotion test with minimum amount 5 organisms which include bare minimum 1 fungus.

TYMC is by definition yeasts and molds count so growth promotion with germs is not really vital. SDA with antibiotics might be applied as a substitute if the TYMC is predicted to exceed the acceptance criterion due to bacterial growth.

1. The standard quantity of colonies on the new batch of the medium have to be “equivalent” to the typical amount of colonies over the Earlier authorised batch. A quantitative definition of “equivalent” is just not founded by the USP, Ph. Eur. or JP.
