Production of Penicillin Murdoch University

Penicillin is a group of antibiotics, a secondary metabolite from the fungus Penicillium and is produced when growth of the fungus is inhibited by stress. Penicillin G is the most widely used form of penicillin. It is produced in a batch culture. It has a bacteriostatic effect on spore forming bacteria.

Free Biotechnology Notes: PENICILLIN PRODUCTION

This allows tweaking of the process to occur and difficulties to be examined. For example, there may not be enough oxygen getting to the culture and hence it will be oxygen starved. At this point, the cells should be showing filamentous morphology, as this is preferred for penicillin production. As before, cell growth is priority at this stage.
