GENETIC RELATEDNESS OF SPORE BEARING BACILLI STUDIED BY THE DNA AGAR METHOD

Abstract

The DNA-DNA hybridization was studied by the DNA-agar method using ³²P-labelled DNA of Bacillus subtilis Marburg and unlabelled DNA of eighteen strains of Bacilli. DNA's of several strains of B. natto and B. megaterium made hybrids with DNA of B. subtilis and the extent of hybridization correlated well with the genetic relatedness that had been studied by the interspecific transformation and phage-susceptibility.
