Sterilization Process in Microbiology- Part 02- Chemical. After using a broadscale, nonselective physical method such as flooding or tilling, revegetation may be necessary to reestablish desirable plant communities. Revegetation with desirable and competitive plant species is the best long term, sustainable method of suppressing or preventing the establishment of invasive plants (DiTomaso 2000)., The destruction of a microbial population subjected to a sterilization process follows a geometrical progression – to be 100% certain the article is sterile it would require infinite sterilisation..
