When it comes to survival, bacteria have one impressive trick up their sleeve — endospores. These microscopic structures are some of the toughest biological entities on Earth, capable of withstanding heat, radiation, chemicals, and even the vacuum of space. But…
Heat is widely recognized as one of the most effective sterilizing agents due to its ability to inactivate or kill microorganisms, including bacteria, viruses, and spores. There are two main types of heat sterilization: moist heat and dry heat. Both…
Microorganisms can cause diseases, spoil food, and contaminate laboratory samples. To control microorganisms, physical, chemical, and biological methods are used. Physical methods include heat, radiation, and filtration. Chemical methods include disinfectants, antiseptics, and antibiotics. Biological methods include beneficial microorganisms, such…
Tyndallization is an alternative sterilization method. It is a physical method of sterilization that uses moist heat (steam) for sterilization. It is also known as fractional sterilization and intermittent sterilization. Physicist Dr. John Tyndall invented this technique of tyndallization in…
