can we use streaking within the floor of slective media as selective media use only or qualitative analysis?

), inoculating Just about every plate with a little variety (not much more than a hundred cfu) of the right microorganism. Incubate at the desired temperature for not a lot more than the shortest timeframe laid out in the test. Growth on the microorganism akin to that previously acquired using a Formerly tested and authorised batch of medium occurs.
