S. epidermidis thrives in warm, moist environments and is a common bacteria of the human microbiome; [18] it is thus primarily responsible for foot odor as feet have more sweat glands than any other part of the body and thus are often moist, which creates an ideal environment for S. epidermidis to thrive.
The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis. [1] The epidermal layer provides a barrier to infection from environmental pathogens [2] and regulates the amount of water released from the body into the atmosphere through transepidermal water loss.
Potential probiotic treatment includes the use of Staphylococcus epidermidis to inhibit C. acnes growth. S. epidermidis produces succinic acid which has been shown to inhibit C. acnes growth. [42] Lactobacillus plantarum has also been shown to act as an anti-inflammatory and improve antimicrobial properties of the skin when applied topically ...
Voges–Proskauer / ˈ f oʊ ɡ ə s ˈ p r ɒ s k aʊ. ər / or VP is a test used to detect acetoin in a bacterial broth culture. The test is performed by adding alpha-naphthol and potassium hydroxide to the Voges-Proskauer broth, which is a glucose-phosphate broth that has been inoculated with bacteria. A cherry red color indicates a positive ...
If 'negative', the plasma remains a liquid. The negative result may be S. epidermidis but only a more detailed identification test can confirm this, using biochemical tests as in analytical profile index tests methods. A false negative can be perceived if the sample is not allowed to cool for about 30 minutes at room temperature or 10 minutes ...
Pie charts of typical human body composition by percent of mass, and by percent of atomic composition (atomic percent) Body composition may be analyzed in various ways. This can be done in terms of the chemical elements present, or by molecular structure e.g., water , protein , fats (or lipids ), hydroxyapatite (in bones), carbohydrates (such ...
In molecular biology, bacterial DNA binding proteins are a family of small, usually basic proteins of about 90 residues that bind DNA and are known as histone-like proteins. [ 1 ] [ 2 ] Since bacterial binding proteins have a diversity of functions, it has been difficult to develop a common function for all of them.
A biomolecule or biological molecule is loosely defined as a molecule produced by a living organism and essential to one or more typically biological processes. [1] Biomolecules include large macromolecules such as proteins , carbohydrates , lipids , and nucleic acids , as well as small molecules such as vitamins and hormones.
