Transferring Bacteria Using an Inoculation Loop
After the inoculation wand is sterilized and given a moment to cool, the wire end with the loop is gently touched to a bacterial colony on a source plate, or dipped into a test tube of liquid inoculate, and then that sample is smeared onto a new sterile plate, typically using streak plate technique.
Inoculation Loop to Transfer Bacteria - P2
There are typically two ways to sterilize an inoculation wand in a microbiology laboratory--by using an open flame, such as a Bunsen burner, or, a safer and more convenient way, to use a microincinerator.

The freshly inoculated plate is then incubated for at least 24 hours, after which time many types of bacterial colonies should be visible.
