    1. Make drawings of the 5 plates from the ultraviolet light experiment.

    3 second UV exposure; lid off

    5 second UV exposure; lid off

    30 second UV exposure; lid on

    Conclusions:

    2. Observe the plates exposed to UV light for any non-pigmented colonies. Aseptically pick-off one of these nonpigmented colonies and streak it in a plate of Trypticase Soy agar. Incubate at room temperature until the next lab period.

    3. After incubation, observe the plate you streaked with the nonpigmented colony.

    Does the organism still lack chromogenicity?

    What would account for this?
