A hydroxide ion acting as a nucleophile in an S N 2 reaction, converting a haloalkane into an alcohol. In chemistry, a nucleophile is a chemical species that forms bonds by donating an electron pair. All molecules and ions with a free pair of electrons or at least one pi bond can act as nucleophiles. Because nucleophiles donate electrons, they ...
Endospore-forming bacteria can cause disease; for example, anthrax can be contracted by the inhalation of Bacillus anthracis endospores, and contamination of deep puncture wounds with Clostridium tetani endospores causes tetanus, which, like botulism, is caused by a toxin released by the bacteria that grow from the spores.

This list of sequenced eubacterial genomes contains most of the eubacteria known to have publicly available complete genome sequences.Most of these sequences have been placed in the International Nucleotide Sequence Database Collaboration, a public database which can be searched [1] on the web.
This article lists the orders of the Bacteria.The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) [1] and National Center for Biotechnology Information (NCBI) [2] and the phylogeny is based on 16S rRNA-based LTP release 132 by The All-Species Living Tree Project.
This is a list of bacteria that are significant in medicine. For viruses, see list of viruses A ...
Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota.Enterococci are Gram-positive cocci that often occur in pairs or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [2]
Bacteria (Cohn 1872 b) [27] Schizomycetaceae (DeToni and Trevisan 1889) [28] Furthermore, the families into which the class was subdivided changed from author to author and for some, such as Zipf, the names were in German and not in Latin. [29] The first edition of the Bacteriological Code in 1947 sorted out several problems. [30] [example needed]
