Evaluation of Escherichia coli cells damages induced by ultraviolet and proton beam radiation

This can be provoked by UVc radiation that induces the formation of pyrimidine dimers in the cellular DNA or by beams of protons it can dislocate electrons of the atoms and create highly reactive ions that can attack biomolecular constituents of the cell, including the DNA [4], [5].

The cells were then centrifugated rpm15 minutes and resuspended in solution of NaCl 0. At the present work possible transformations on E.


The biochemical test carried out was the following: By microscopic observations it was noticed that the E. Loewenstein WR, Mendelson M.

Some mutations are undesirable and even lethal, however, some can be interesting for the survival of a species [1], [2], [4].

How to cite this article. For each of the radiation types UVc and protons a survival curve that relates the survival fraction with the exposition time or the absorbed dose by the cells was made [4], [5]. The prokaryotes compose an interesting group of microorganisms, which can be used as instruments of scientific investigation.

The existence of the so called hormesis phenomenon is also registered, with stimulated or benefic effect, induced by low doses of a radioactive agent. A cellular survival curve versus exposition time and absorbed dose was built for each case. Morphological and physiological alterations occurred in Escherichia coli E.
