Adsorption capability determines phage plaque size on<i>Streptomyces antibioticus</i>producing endodeoxyribonuclease

Abstract

Differences in plaque size of phages developing in Streptomyces antibiotics on several media were mainly determined by their adsorption ability to mycelium obtained at different stages of the bacterial growth-curve. This is due to the exposure of phages to the exocytoplasmic endodeoxyribonuclease produced by this bacterium at the middle-end of the exponential phase.
