Question

You accidentally streaked E. coli onto a plate you were supposed to streak D. radiodurans. You have no extra plates and decide to fix your conundrum by exposing the plate to UV for 30min. You decide to leave the lid on during the exposure to prevent further contamination. You then streak the plate with D. radiodurans. What are the expected results after incubation

Answer 1

Answer:

Explanation:

The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.

As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.

As a result of incubation there will be growth of both of the organism in the petri dish.
