Production of antibiotics
Penicillins and cephalosporins are antibiotics derived from fungi

Antibiotics can also be derived from other bacteria. These include aminoglycosides and carbapenems

Newer antibiotics are synthetically made, usually by modifying the chemical structure of naturally occurring antibiotics

Chemically synthesised antibiotics include quinolones and sulfonamides
