If colonies of Gram-damaging rods matching the description in Desk four are identified, continue with additional identification by transferring representative suspect colonies individually, by way of an inoculating wire, to some butt-slant tube of Triple Sugar&#one hundred fifty;Iron&#one hundred fifty;Agar Medium by first streaking the area with the slant after which you can stabbing the wire very well beneath the area.

The plates are going to be incubated for forty eight hrs. College students will then count colonies on plates with thirty-300 colonies and use these counts to determine CFU/ml for every first sample. Performing practical plate counts enables estimation of the number of feasible microorganisms in a very supplied sample.
