Ninhydrin is most commonly used to detect fingerprints in forensic cases, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin. [2] [3] Ninhydrin is a white solid that is soluble in ethanol and acetone. [1] Ninhydrin can be considered as the hydrate of indane-1,2,3-trione.

Nitrifying bacteria are present in distinct taxonomical groups and are found in highest numbers where considerable amounts of ammonia are present (such as areas with extensive protein decomposition, and sewage treatment plants). [3] Nitrifying bacteria thrive in lakes, streams, and rivers with high inputs and outputs of sewage, wastewater and ...
Protein production is the biotechnological process of generating a specific protein. It is typically achieved by the manipulation of gene expression in an organism such that it expresses large amounts of a recombinant gene .
Protein detection is used for clinical diagnosis, treatment and biological research. [1] Protein detection evaluates the concentration and amount of different proteins in a particular specimen. [2] There are different methods and techniques to detect protein in different organisms.
α-Hemolysin from S.aureus. Pore-forming proteins (PFTs, also known as pore-forming toxins) are usually produced by bacteria, and include a number of protein exotoxins but may also be produced by other organisms such as apple snails that produce perivitellin-2 [1] [2] or earthworms, who produce lysenin.
Tetracyclines are generally used in the treatment of infections of the urinary tract, respiratory tract, and the intestines and are also used in the treatment of chlamydia, especially in patients allergic to β-lactams and macrolides; however, their use for these indications is less popular than it once was due to widespread development of resistance in the causative organisms.
Antibiotic resistance tests: Bacteria are streaked on dishes with white disks, each impregnated with a different antibiotic. Clear rings, such as those on the left, show that bacteria have not grown—indicating that these bacteria are not resistant. The bacteria on the right are fully resistant to all but two of the seven antibiotics tested. [33]
