Some members of the genus produce penicillin, a molecule used as an antibiotic that kills or stops the growth of certain kinds of bacteria inside the body.

Penicillin works best on gram-positive bacteria by inhibiting peptidoglycan production, making the cells leaky and fragile. The cells burst open and are much easier for the immune system to break down, which helps the sick person heal more quickly.

Is Penicillium a parasite?

Penicillium belongs to the ascomycetes group of fungi which feed on dead and decay material, they produce mycotoxins which cause food poisoning. Hence, all these share the same type of mode of nutrition which is the Saprophytic mode as all of them feed on decay and dead source. The correct option is B) Saprophytic.

What does penicillin do to bacteria?

Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall (Figure 8). When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.

Tetracyclines (e.g. doxycycline), quinolones (e.g. ciprofloxacin), macrolides (e.g. clarithromycin), aminoglycosides (e.g. gentamicin) and glycopeptides (e.g. vancomycin) are all unrelated to penicillins and are safe to use in the penicillin allergic patient.
