GENETIC MAPPING OF A BACTERIOCINOGENIC FACTOR IN PSEUDOMONAS AERUGINOSA

II. MAPPING OF PYOCIN R2 FACTOR BY TRANSDUCTION WITH PHAGE F116

Abstract

A pyocinogenic factor responsible for the production of pyocin R2 was analyzed by transduction with phage F116. The pyocin factor could be transferred linked to a tryptophan marker. The pyocin-less character could also be transduced. It is concluded that the pyocinogenic factor is incorporated into the bacterial chromosome close to a str-trp-1 region. The relationship between pyocins and bacteriophages is discussed.
