Question

A research laboratory is investigating environmental factors that would inhibit the growth of Archaea. One question they have is whether adding the antibiotic penicillin would be effective in controlling their growth. What do you think the outcome would be if they tried this?

Answer 1

The penicillin wouldn't affect the Archaea because it prevents the cross linking of peptidoglycan- Archaea don't have this compound in their cell walls.
