Creating the right environment for growth was the first step in producing enough penicillin to be used as a drug. In Oxford, experiments showed that Penicillium notatum grew best in small shallow containers on a broth of nutrients. Penicillium need lots of air.
  Without fully explaining how the penicillin antibitic works: yes, archaea are resistant to penicillin. This is because they don't have peptidoglycan in their cell wall. â¦ Penicillin works by lowering the newly formed peptidoglycan in multiplying bacteria.It also does other things.The reason it works (this is natural penicillin G) only on Gr+ is because the can't get through the GR-cell wall.his is because they don't have peptidoglycan in their cell wall. â¦ Penicillin works by lowering the newly formed peptidoglycan in multiplying bacteria. It also does other things.
