Penicilloic V acid is a chromatographic isomer that belongs to the group of β-lactams. It is produced by fungi in the genus Penicillium, and has been shown to be an extracellular metabolite with linear growth at acidic pH values. Penicilloic V acid inhibits bacterial growth by binding to enzymes in the cell wall synthesis, including β-lactamase, which are responsible for breaking down penicillin. This compound also has a linear response in a variety of different solvents, including water, methanol, and acetonitrile.
