Introduction Citrate Utilization Test is a commonly used test in bacteriology to determine the ability of bacteria to use citrate as the sole carbon source for their growth. This test is an important tool for the identification and classification of…
Introduction The Indole test was first introduced by Nirenberg and Mattei in 1958. Since then, it has become a widely used test in microbiology laboratories for bacterial identification. The test is simple, rapid, and reliable and can provide valuable information…
Introduction The coagulase test is a laboratory technique used to identify Staphylococcus aureus, a gram-positive bacterium that is commonly found on the skin and mucous membranes of humans and animals. The test is based on the detection of the enzyme…
Introduction Fungi are eukaryotic, heterotrophic, non-photosynthetic organisms in their own kingdom. The majority is made up of microscopic filaments known as hyphae, and the network of filaments is known as mycelium. They exist as parasites or saprophytes, absorbing organic material…
Introduction The catalase test is a laboratory diagnostic test that is used to identify the presence of catalase enzymes in bacterial cells. The catalase enzyme helps in breaking down hydrogen peroxide (H2O2) into water and oxygen, which is an essential…
Principle of the Semi-Solid agar Method The semi-solid agar method is a widely used technique in microbiology for determining bacterial motility. The method involves inoculating a bacterial culture into a semi-solid agar medium with a reduced agar concentration (0.2-0.5%) that…
History of digital microscope 1986 saw the creation of an early digital microscope by the now-known Hirox Co. LTD company, which was based in Tokyo, Japan. It had a lens attached to a computer and a control box. Initially, an…
Principle The motility test by hanging drop method is a laboratory technique used to observe the motility of bacteria. The principle behind the hanging drop method is based on the fact that the movement of bacteria can be observed by…
Introduction Bacterial motility testing refers to the ability of bacteria to move from one location to another through self-propulsion. This movement can be observed under the microscope and is important for many aspects of bacterial behavior, such as finding nutrients,…
Introduction Yeast is a type of fungus that belongs to the kingdom of Fungi. It is a unicellular microorganism that is commonly found in soil, water, and on plant surfaces. Yeast is an important organism in various industries, including baking,…
