Bacteriology

A biofilm is any group of microorganisms in which cells stick to each other and often these cells adhere to a surface.

Gram staining, also called Gram's method, is a method of staining used to differentiate bacterial species into two large groups (gram-positive and gram-negative).

The human microbiota is the aggregate of microorganisms, a microbiome that resides on or within a number of tissues and biofluids, including the skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, and gastrointestinal tracts.

Probiotics are microorganisms that are believed to provide health benefits when consumed.

Phycobilisomes are light harvesting antennae of photosystem II in cyanobacteria, red algae and glaucophytes.

Optochin (or ethylhydrocupreine hydrochloride) is a derivative of hydroquinine introduced in 1911 by Morgenroth and Levy with the intention to treat pneumococci infection.

Bacterial growth is the asexual reproduction, or cell division, of a bacterium into two daughter cells, in a process called binary fission.

The gut–brain axis is the biochemical signaling that takes place between the gastrointestinal tract and the central nervous system.

Adhesins are cell-surface components or appendages of bacteria that facilitate adhesion or adherence to other cells or to surfaces.

'The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of Bacteria and Archaea.

Microcystins (or cyanoginosins) are a class of toxins produced by certain freshwater cyanobacteria; primarily Microcystis aeruginosa but also other Microcystis, as well as members of the Planktothrix, Anabaena, Oscillatoria and Nostoc genera.

The hok/sok system is a postsegregational killing mechanism employed by the R1 plasmid in Escherichia coli.

Reuterin is a potent antimicrobial multi-compound produced by Lactobacillus reuteri, during the metabolism of glycerol to 1,3-propanediol catalysed by the coenzyme B12-dependent diol dehydrase.
