Summary
1. Cells ofL. casei grown in presence of penicillin are found to contain decreased amounts of PNA, DNA being unaffected.
2. PGA by itself and, more effectively, in presence of vitamin B12 exerts protection against the inhibitory action of the antibiotic on growth as well as on PNA formation.
