Relationship of Bacillus subtilis clades associated with strains 168 and W23: a proposal for Bacillus subtilis subsp. subtilis subsp. nov. and Bacillus subtilis subsp. spizizenii subsp. nov.
Earlier phylogenetic studies based on the inferred DNA sequences of the polC, rpoB and gyrA genes suggested that strains of the species Bacillus subtilis formed two clusters, indicating the presence two closely related taxa; one contained the laboratory strain 168 and the other the laboratory strain W23. Significant sexual isolation was found between strain 168 and members of the group containi...
متن کاملDeath of Bacillus subtilis Auxotrophs Due to Deprivation of Thymine, Tryptophan, or Uracil.
Pritikin, William B. (University of California, Los Angeles), and W. R. Romig. Death of Bacillus subtilis auxotrophs due to deprivation of thymine, tryptophan, or uracil, J. Bacteriol. 92:291-296. 1966.-Auxotrophic mutants of Bacillus subtilis 168 that require either tryptophan, uracil, or thymine died rapidly when deprived of any of these compounds. Phage PBS1 was produced by infected B. subti...
متن کاملIntroduction of host-controlled modification and restriction systems of Bacillus subtilis IAM1247 into Bacillus subtilis 168.
Bacillus subtilis IAM1247 had two modification and restriction systems (Bsu1247I and Bsu1247II), the former producing an isoschizomer of PstI endonuclease. A transformant clone was isolated which had Bsu 168, BsuR, and Bsu1247I systems coexisting within a genome.
متن کاملIsolation of a Bacillus subtilis 168 derivative sensitive to defective bacteriophage PBSX.
A derivative of Bacillus subtilis strain 168 sensitive to defective bacteriophages PBSX and PBSZ has been isolated. This particular strain, RUB824, carries the genetic information for defective bacteriophage PBSX.

ABSTRACr Plasmid pUB10 (-2.8 X 106 daltons), originally detected in Staphylococcus aureus, specifies resistance to neomycin and has been transformed into Bacillus subtilis 168. In B. subtifis, pUBllO is stably maintained at about 50 copies per chromosome and renders the host resistant to neomycin sulfate at 5 jg/ml. pUBlIO isolated from B. subtifis transforms Rec+ and recE4-containing strains o...
