[Effect of microwaves on the vegetative and spore forms of Bacillus stearothermophilus].
Microwave irradiation provides a rapid and effective method for sterilization of stainless steel scalpel blades or cover glasses contaminated by B. stearothermophilus. A study by SEM of vegetative forms showed that microwave irradiation induce a progressive series of alterations and finally the complete destruction of the microorganism. On the contrary there were no significant morphological variations of the spores after lethal irradiation by microwaves.
