The study of the effect of Glycerol on survival of the E.coli shew Glycerol could protect E.coli and improve dry, vacuum and implantational survival rate during ion beam implanting the E.coli. The whole survival rate of protected the E.coli implanted by 30keV N+ was 530-10000 times higher than unprotect ones. Glycerol changed bacteria outer color and survival rate curve. At the same doses, the color of the E.coli protected by five and one percent Glycerol was white or yellow, lighter than unprotected.
