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.

Microorganisms are used for many commercial and industrial purposes, including the production of chemicals, enzymes and other bioactive molecules, often through protein engineering. For example, acetic acid is produced by the bacterium Acetobacter aceti, while citric acid is produced by the fungus Aspergillus niger. Microorganisms are used to ...
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.
The non-pathogenic and gram-negative bacteria, Pseudomonas fluorescens, is used for high level production of recombinant proteins; commonly for the development bio-therapeutics and vaccines. P. fluorescens is a metabolically versatile organism, allowing for high throughput screening and rapid development of complex proteins.
Design of engineered live bacterial therapeutics [1]. Bacterial therapy is the therapeutic use of bacteria to treat diseases.Bacterial therapeutics are living medicines, and may be wild type bacteria (often in the form of probiotics) or bacteria that have been genetically engineered to possess therapeutic properties that is injected into a patient.
Atlantic horseshoe crab Limulus polyphemus. Limulus amebocyte lysate (LAL) is an aqueous extract of motile blood cells from the Atlantic horseshoe crab Limulus polyphemus.LAL reacts with bacterial endotoxins such as lipopolysaccharides (LPS), which are components of the bacterial capsule, the outermost membrane of cell envelope of gram-negative bacteria.
Below is a list of differential techniques and results that can help to identify Bacillus licheniformis from other bacteria and Bacillus species. [27] Anaerobic Growth: Positive; Voges Proskauer test: Positive; Acid produced from D-glucose: Positive; L-arabinose: Positive; D-mannitol: Positive; Starch hydrolysis: Positive; Nitrate reduction ...
