Penicillin G is a natural penicillin that is produced directly from fermentation of Penicillium crysogenum. Penicillin V is a derivative of penicillin G and because of similarities in spectrum of activity, is considered a natural penicillin.
Is penicillin G the same as penicillin?
Penicillin G and penicillin V (phenoxymethylpenicillin) are “natural” penicillins, with a narrow-spectrum of activity due to the development of penicillinases (β-lactamases active against penicillins). Staphylococci, initially sensitive to penicillin G, are now considered highly resistant.
Why some penicillins are called penicillin G and penicillin V?
The two so-called natural penicillins are both produced biosynthetically from Penicillium chrysogenum by fermentation. Benzylpenicillin (penicillin G) is formed if phenylacetic acid is added to the culture medium and Phenoxymethylpenicillin (penicillin V) is formed when phenoxyacetic acid is added.

Benzathine benzylpenicillin, also known as benzathine penicillin G, is an antibiotic medication useful for the treatment of a number of bacterial infections.
Is penicillin gram-positive or negative?
Gram-positive bacteria have a peptidoglycan layer on the outside of the cell wall. Gram-negative bacteria have peptidoglycan between membranes. Penicillin works best on gram-positive bacteria by inhibiting peptidoglycan production, making the cells leaky and fragile.

Which is stronger amoxicillin or Flucloxacillin?
Although both antibiotics are effective against Group A beta haemolytic streptococci, the minimum inhibitory concentration for amoxicillin is lower than that for flucloxacillin (≤0.03µg/ml for amoxicillin versus and 0.1 µg/ml for flucloxacillin) (Istre el at 1981, Medsafe, accessed 19.02. 2010).
