If any new media obtaining for The 1st time, then inoculated microorganism shall be taken for calculation.
You might establish a turbidimetric calibration curve or use another suited method and Then you certainly can get an estimate in the concentration of the inoculum.
can we use streaking within the surface area of slective media as selective media use only or qualitative Examination?
This is confirmed by identification tests. The products complies Together with the test if colonies of the kinds described will not be existing or When the confirmatory identification tests are detrimental.
