Transduction in Bacillus subtilis by bacteriophage SPP1.
Lysates of the virulent bacteriophage SPP1 were shown to be capable of mediating generalized transduction. Suppressible mutants of this bacteriophage (sus) were capable of transduction at a lower multiplicity of infection than virulent SPP1. Linkage analysis demonstrated that bacteriophage SPP1 transduced segments of the genome equal in size to that transferred by SP10. This bacteriophage shoul...
متن کاملTransduction in Bacillus subtilis.
Thorne, Curtis B. (Fort Detrick, Frederick, Md.). Transduction in Bacillus subtilis. J. Bacteriol. 83:106-111. 1962.-A bacteriophage, SP-10, isolated from soil carries out general transduction in Bacillus subtilis. Phage propagated on a streptomycin-resistant mutant of the wild-type strain W-23 was capable of transducing to prototrophy strain 168 (indole(-)), as well as all of the auxotrophic m...
متن کاملSpecialized transduction of the ilvD-thyB-ilvA region mediated by Bacillus subtilis bacteriophage SP beta.
Specialized transducing SP beta particles were found that carried the Bacillus subtilis genes lying to the left of the prophage attachment site. Three classes of transducing particles were differentiated, depending upon whether they carried ilvA only, thyB and ilvA, or ilvD, thyB, and ilvA. Lysates prepared by the induction of strains that carried both a transducing phage and a plaque-forming p...
متن کاملPRODUCTION OF a-Amylase FROM BANANA PEEL BY Bacillus subtilis
We produced a-amylase from banana peel by Bacillus subtilis through solid state fermentation (SSF). Addition of yeast extract, corn steep liquor, sodium dodesyl sulphate (SDS) and Tween-80 enhanced the a-amylase production under preoptimized fermentation conditions. Maximum enzyme yield (10.25 U/mL) was observed at 35°C after 24 hours of SSF in growth medium containing 0.1% yeast extract, 1% co...
متن کاملBacteriophage Deoxyribonucleate Infection of Competent Bacillus Subtilis.
Reilly, Bernard E. (Western Reserve University, Cleveland, Ohio), and John Spizizen. Bacteriophage deoxyribonucleate infection of competent Bacillus subtilis. J. Bacteriol. 89:782-790. 1964.-Phenol extracts of the Bacillus subtilis bacteriophages phi1, phi25, and phi29 contained infectious deoxyribonucleic acid. The infectivity was destroyed by catalytic amounts of deoxyribonuclease but not by ...
