Which one is better D or E

E in my opinion.

Look at "which includes" in the option D. It should have been used with a singular noun. But here we are talking of "effects" which 'include'.

E correctly uses the colon to list out the different effects.

I think we are not talking of effects here, instead we are talking of bacterial deterioration.

I think after : which includes is not needed at at all.
You can consider : similar to namely
It almost always helps.
