I know both are antibiotics resistance but we are using just ampicillin for e.coli culture. I need the information about what is the difference and which is the good result of the culture of e.coli agar media.
Hi, ampicillin is cell wall inhibitor while kanamycin inhibits protein synthesis. To know more about the antibiotics, you can google and you will need to know why you need the antibiotics in your agar media? Does it serve to inhibit the bacteria growth or what?
The ampicillin is working on inhibition of cell wall in gram negative bacteria . Kanamycin is working on stopping the protein synthesis in gram positive and negative bacteria.
Precisely, ampicillin is an irreversible inhibitor of transpeptidase that involved in the cross-linkage of petptidoglycan layer in cell wall synthesis. The inhibition blocks the binary fission and leads to cell lysis, ampicillin is a BACTERICIDAL agent. On the other side kanamycin inhibits the protein synthesis by blocking the 30s subunit of the ribosome. Kanamycin acts as an BACTERISTATIC agent it arrests the growth and proliferation of cells.
