It is shown that the solutions of 2.8 mL distilled water and 0.1 mL LB and 0.1 mL PBS is the best,because it not only supplies good living condition but also has less effect on the spectra of E.coli. And it was found that UV in spectrophotometer has no effect on the mensuration result. On the basis of these studies the absorption spectra of E.coli irradiated by different doses UV were investigated. It is shown that there is a declining-rising-declining phenomenon in the spectra of E.coli with the dose increasing. This reflects the wound healing process of E.coli. Spectroscopic technique is helpful for the study of cell’s wound healing.
