What is Freeze Fracture Technique? Principle of Freeze Fracture Technique The principle of the freeze-fracture technique is based on the physical separation of biological membranes at their hydrophobic core when the sample is frozen and then fractured. Here are the key aspects of this principle: Overall, the freeze-fracture technique provides valuable insights into the functional … Read more

Gram-staining used to differentiate between Gram-Positive and Gram-Negative Bacteria.
Acetoacetic acid and acetone react with an alkaline solution of sodium nitroprusside to form a purple-colored complex. This method can detect above 1-5 mg/dl of acetoacetic acid and 10-20 mg/dl of acetone. Beta-hydroxybutyrate is not detected.
An electron microscope is a type of microscope that uses a beam of electrons to create an image of a sample. Electron microscopes have a higher resolution than optical microscopes, which use light to form an image, and can be used to observe objects that are too small to be seen with an optical microscope. … Read more
Starch casein agar can be described as an nutrient-rich medium that is used for the cultivation and growth of the saccharolytic marine bacteria.
What is gas chromatography? Definition of Gas chromatography Gas chromatography (GC) is an analytical technique used to separate, identify, and quantify volatile compounds in a mixture by passing them through a column with a stationary phase and a carrier gas. Principle of Gas chromatography How does gas chromatography work? (Mechanism of Separation in Gas Chromatography) … Read more
Why we need to Validate an Autoclave? Validating an autoclave is crucial for ensuring the sterilization process is effective and reliable. Here’s why validation is necessary: Methods for Autoclave Validation Autoclave validation is a critical process in ensuring that sterilization procedures are effective and reliable. This is particularly important in the pharmaceutical industry, where sterility … Read more
When it comes to culturing bacteria, it is crucial to create the same environmental and nutritional conditions as those found in the natural environment. The majority of culture mediums contain water, which is a major source of carbon and energy and nitrogen. It also contains trace elements, as well as some growth factors. In addition, the pH as well as oxygen tension and Osmolarity must also be considered. Some of the components of media for culture include: Although tap water is appropriate for the use of culture media, it shouldn’t be used in the event that it contains a significant amounts of minerals. In these instances the use of demineralised or distillated water is recommended.
What is Simple Microscope? Definition of Simple Microscope A simple microscope is an optical device consisting of a single convex lens that magnifies objects by enlarging their image through light refraction. Principle of Simple Microscope Working Mechanism of Simple Microscope This ray diagram in below, explains how simple microscopes is working; Magnification of a simple … Read more
