replication and recombination in ligase-deficient rii bacteriophage t4d.deoxyribonucleic acid replication and genetic recombination were investigated after infection of escherichia coli with ligase-deficient rii bacteriophage t4d. the major observations are: (i) deoxyribonucleic acid synthesis is discontinuous, (ii) the discontinuities are more slowly repaired than in wild-type infection, (iii) host ligase is required for viability, and (iv) genetic recombination is increased.19714939386

monitoring of low-level virus in natural waters.the insoluble polyelectrolyte technique for concentrating virus is extended to extremely low virus levels. the effectiveness of this method employing a coliphage t2 model is a constant 20% over a range of virus levels from 10(3) to 10(-4) plaque-forming units/ml. the efficiency of the method is dependent upon ph control during the concentration phase. although the study was initiated to develop a method for quantitating the effectiveness of water and wastewater treatment methods for the removal ...19714940873
effect of plate size and location of disc on zone diameter in the disc antimicrobial susceptibility established standard antimicrobial disc susceptibility test recommends the use of a 150-mm petri dish. many workers substitute 100-mm plates and use various types of mechanical dispensers. a comparison of zone diameters was made by testing staphylococcus aureus and escherichia coli against penicillin and chloramphenicol with the use of these different sized plates and dispensers. zone diameters were consistently smaller at the edges of plates than in the center (0.4 to 1.2 mm). significant sm ...19714940875

localized mutagenesis of any specific small region of the bacterial chromosome.a method, which we call localized mutagenesis, is described for the isolation of temperature-sensitive and other types of mutations in any specific small region (about 1%) of the bacterial chromosome. the principle of this method is to mutate the transducing dna rather than the bacterial dna. one can select for the introduction of this mutated dna into any particular region of the bacterial chromosome by transducing an auxotrophic marker in that region to prototrophy, thereby introducing new mut ...19714943557
kinetic studies on klebsiella pneumoniae nitrogenase.purified cell-free extracts of klebsiella pneumoniae reduce n(2), n(3) (-), cn(-), or c(2)h(2) in the absence of an atp-generating system when substrate concentrations of atp are used. the optimum mg(++)/atp ratio is 0.5. michaelis constants for the reduction of substrates calculated from kinetic studies of k. pneumoniae nitrogenase were similar to those that have been reported for azotobacter vinelandii and clostridium pasteurianum. hill plots of the kinetic data are consistent with the view th ...19714943781
purification and in vitro transcription of a transfer rna gene.a gene specifying tyrosine transfer rna has been purified and transcribed in vitro. the purification procedure made use of two specialized transducing phages carrying the trna(tyr) gene of escherichia coli inserted into their dna in opposite orientations. the separated heavy strands of the two phages were annealed and the single-stranded tails of the resulting hybrid were removed by digestion with neurospora endonuclease. the size of the purified double-stranded structures was determined by elec ...19714943795
the presence and possible role of zinc in rna polymerase obtained from escherichia coli.highly purified preparations of the dna-dependent rna polymerase obtained from escherichia coli contain about 2 g-atoms of tightly bound zinc per mol (molecular weight 370,000) of enzyme. when the purified enzyme is fractionated on sephadex g-150 or g-200, correlation is observed between the zinc and enzymic activity. although some of the preparations examined also contain iron, copper, and magnesium, the content of these metal ions show no consistent correlation with rna polymerase activity. in ...19714944629

transduction of the nitrogen-fixation genes in klebsiella pneumoniae.the bacteriophage p1 infects and functions as a generalized transducing phage for nitrogen-fixing strains of the coliform bacterium klebsiella pneumoniae. bacterial mutants (nif(-)) unable to grow on molecular nitrogen as a nitrogen source were found to be deficient in nitrogenase activity as assayed by the conversion of acetylene to ethylene. these mutants regained normal nitrogenase activity and the ability to grow on n(2) after transduction with lysates of p1 phage prepared from wild-type bac ...19715288365
