Summary Introduction
To tell:
The ability of disinfectants and antiseptic in denaturing proteins and the effect of denaturation in killing of cells.
Introduction:
The term aseptic refers to condition completely devoid of microbes. The sterilization, disinfectant, sanitization, and radiation are some of physical and chemical methods used to get rid of microbes.
