An exoenzyme, or extracellular enzyme, is an enzyme that is secreted by a cell and functions outside that cell. Exoenzymes are produced by both prokaryotic and eukaryotic cells and have been shown to be a crucial component of many biological processes .
NETs formed in blood vessels can catch circulating bacteria as they pass through the vessels. Trapping of bacteria under flow has been imaged directly in flow chambers in vitro and intravital microscopy demonstrated that bacterial trapping occurs in the liver sinusoids and lung capillaries (sites where platelets bind neutrophils).

Calymmatobacterium granulomatis; Campylobacter. Campylobacter coli; Campylobacter fetus; Campylobacter jejuni; Campylobacter pylori; Capnocytophaga canimorsus
While exoelectrogen is the predominant name, other terms have been used: electrochemically active bacteria, anode respiring bacteria, and electricigens. [1] Electrons exocytosed in this fashion are produced following ATP production using an electron transport chain (ETC) during oxidative phosphorylation .
The viridans streptococci are a large group of commensal streptococcal Gram-positive bacteria species that are α-hemolytic, producing a green coloration on blood agar plates (hence the name "viridans", from Latin "vĭrĭdis", green), although some species in this group are actually γ-hemolytic, meaning they produce no change on blood agar.

A sample may be taken from the site of a suspected infection; such as a blood culture sample when bacteria are suspected to be present in the bloodstream (bacteraemia), a sputum sample in the case of a pneumonia, or a urine sample in the case of a urinary tract infection. Sometimes multiple samples may be taken if the source of an infection is ...
Test Strips: The system consists of a plastic strip containing 20 small reaction tubes (microtubes), each containing different dehydrated substrates. Rehydration and Inoculation: To perform the test, the microtubes are rehydrated with a bacterial suspension. Each microtube is designed to detect specific enzymatic activities or carbohydrate ...
Bacterial cellulose is a versatile structural material, allowing it to be shaped in a variety of ways to accommodate different uses. A number of patents have been issued for processes involving this material. [41] Bacterial cellulose pellicles were proposed as a temporary skin substitute in case of human burns and other dermal injuries. [42]
