Effect of penicillin irradiation on bacterial growth and penicillin resistance


, : Effect of penicillin irradiation on bacterial growth and penicillin resistance. ChemoTherapy 20(4): 227-234

Interaction between benzylpenicillin and the specific bacterial cell wall receptor is influenced in a non-continuous manner by irradiating the antibiotic with a wavelength of 546 nm. The growth of two B. subtilis strains, one sensitive and the other resistant to penicillin, showed a different response pattern to the irradiated antibiotic. For both strains the activity of the antibiotic was increased by irradiation of 25, and 45 seconds.
