Bacterial endospores appear as refractile bodies under the light microscope. When we say that endospores appear refractile, it means that they scatter light in a way that makes them look shiny or bright under a microscope. In simple terms, refractile…
In the fascinating world of microbiology, even the smallest living things can greatly affect our health and scientific studies. Scientists use sterilization to completely destroy all germs – including bacteria, viruses, fungi, and tough spores. This powerful method keeps laboratories…
There are different methods for the preservation of microbial cultures. Bacteria preservation in glycerol is one of the common method for maintaining bacterial strains over long periods of time. This method involves adding glycerol to a bacterial culture and freezing…
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…
Our life is full of microorganisms. We daily come into contact with thousands of microbes. The water, air, food, soil all contain a wide variety of microbial populations. A microbial population having two or more species of microorganism is a mixed…
