Bacteria

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.

Methanotrophs (sometimes called methanophiles) are prokaryotes that are able to metabolize methane as their only source of carbon and energy.

Coliform bacteria are a commonly used indicator of sanitary quality of foods and water.

Biogenic sulfide corrosion is a bacterially mediated process of forming hydrogen sulfide gas and the subsequent conversion to sulfuric acid that attacks concrete and steel within wastewater environments.

In microbiology, pleomorphism (from greek πλέω- more, and -μορφή form) is the ability of some bacteria to alter their shape or size in response to environmental conditions.

'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.

Bacterial cellulose is an organic compound with the formula (C6H10O5)n) produced by certain types of bacteria.

In medicine, bacteriuria denotes the presence of bacteria in urine (but not if the bacteria's presence is due to contamination from urine sample collection.)

Methicillin-resistant Staphylococcus epidermidis is a bacterium responsible for difficult-to-treat infections in humans.

Multidrug tolerance or antibiotic tolerance is the ability of a disease-causing microorganism to resist killing by antibiotics or other antimicrobials.

Microbial corrosion, also called bacterial corrosion, bio-corrosion, microbiologically influenced corrosion, or microbially induced corrosion (MIC), is corrosion caused or promoted by microorganisms, usually chemoautotrophs.

DD-transpeptidase (EC 3.4.16.4, DD-peptidase, DD-transpeptidase, DD-carboxypeptidase, D-alanyl-D-alanine carboxypeptidase, D-alanyl-D-alanine-cleaving-peptidase, D-alanine carboxypeptidase, D-alanyl carboxypeptidase, and serine-type D-Ala-D-Ala carboxypeptidase.) is a bacterial enzyme that catalyzes the transfer of the R-Laca-D-alanyl moiety of R-L-aca-D-alanyl-D-alanine carbonyl donors to the γ-OH of their active-site serine and from this to a final acceptor.

Small intestinal bacterial overgrowth (SIBO), also termed bacterial overgrowths, or small bowel bacterial overgrowth syndrome (SBBOS), is a disorder of excessive bacterial growth in the small intestine.
