Participation of oxygen in the bacterial transformation of 2,4,6-trinitrotoluene

Biochemistry (Moscow), 2008
The exposure of Bacillus cereus ZS18 cell suspensions to 2,4,6-trinitrotoluene (TNT) in the absence of other oxidizable substrates increases oxygen uptake, exceeding the basal level of respiration of the bacterium 1.5- and 2-fold with 50 and 100 mg/liter of TNT, respectively.

Role of a Deoxyribonuclease in Bacterial Transformation

1974
In the genetic transformation of Diplococcus pneumoniae, donor DNA is converted to single strands either during or just after its uptake by the cell (Lacks, 1962). This conversion may be regarded as the first step in preparation of the DNA for recombination, since a single-strand segment of donor DNA is ultimately inserted into recipient cell DNA (Fox ...

4 Bacterial Transformation with Plasmid DNA

1988
Publisher Summary In general, bacteria that can be transformed by chromosomal DNA can also be transformed by plasmid DNA. However, there are notable differences in the efficiency with which plasmid and chromosomal markers transform competent cells, largely because of the differential processing of various topological forms of DNA.

Molecular Cloning of cDNA: Bacterial Transformation and Screening of Transformants

1983
Once a DNA fragment (or a mixture of DNA fragments) has been ligated into a suitable vector (see Chapter 11), the next step towards the cloning of that DNA fragment is the introduction of the hybrid vector DNA into an appropriate host, usually Escherichia coli. A cell which has acquired a heritable change in its genotype by taking up naked DNA from its
