transduction of sporogenesis in bacillus subtilis.takahashi, i. (mcmaster university, hamilton, ontario, canada). transduction of sporogenesis in bacillus subtilis. j. bacteriol. 89:294-298. 1965.-a number of asporogenous mutants of bacillus subtilis were isolated and genetic analyses with these mutants were carried out by means of transduction mediated by bacteriophage pbs 1. the ability to form spores could be restored by transduction in all mutants examined, with the exception of sp(-)h12-3, although they were not transformable under my expe ...196514255693
localization of spore markers on the chromosome of bacillus subtilis.takahashi, i. (mcmaster university, hamilton, ontario, canada). localization of spore markers on the chromosome of bacillus subtilis. j. bacteriol. 89:1065-1067. 1965.-attempts were made to locate spore markers on the chromosome by determining the mapping distance of ery(r), str(r), phe, tyr, and ser markers to which the spore markers are closely linked. the results obtained indicated that locus sp n2-2 is located near the terminus and loci sp 170-2, sp h12-4, and sp 1 are distributed between th ...196514276096
disinfection of bacillus subtilis spores with chlorine dioxide: a bench-scale and pilot-scale study.chlorine dioxide (clo2) inactivation of bacillus subtilis atcc 19659 spores was examined at pilot-scale during periods representative of winter and summer temperature extremes at the britannia water treatment plant in ottawa, canada. in addition, bench-scale experiments using the same source water (ottawa river, ontario, canada), as well as buffered and unbuffered laboratory waters were conducted using b. subtilis spores. bench-scale inactivation of b. subtilis spores by clo2 was similar to repo ...200211996351
incorporation of bacteriophage genome by spores of bacillus subtilis.takahashi, i. (microbiology research institute, ottawa, ontario, canada). incorporation of bacteriophage genome by spores of bacillus subtilis. j. bacteriol. 87:1499-1502. 1964-the buoyant density in a cscl gradient of deoxyribonucleic acid (dna) extracted from spores of bacillus subtilis was found to be identical to that of dna from vegetative cells. density-gradient centrifugation of dna of spores derived from cultures infected with phage pbs 1 revealed the presence of a minor band whose densi ...196414188727
