My undergraduate lab had pretty "mint green" agar slants with waxy, orange colonies of M. tuberculosis. Handled with much care under the vent hood and with a nice electric incinerator for the needles in place of flaming in a Bunsen burner.

I am unfamiliar with “mint green” and slants.
I also need to quit calling it agar agar. People think I came from a primitive society where plural expression is a little more well, primitive.
