Editing Lactic acid fermentation (section)

== Major genera of lactose-fermenting bacteria==
{{Main|Lactic acid bacteria}}
Some major bacterial strains identified as being able to ferment lactose are in the [[Genus|genera]] ''Escherichia, Citrobacter, Enterobacter'' and ''Klebsiella .'' All four of these groups fall underneath the [[Family (biology)|family]] of ''[[Enterobacteriaceae]].'' These four genera are able to be separated from each other by using biochemical testing, and simple biological tests are readily available. Apart from whole-sequence [[genomics]], common tests include [[Hydrogen sulfide|H2S]] production, [[motility]] and [[Citric acid|citrate]] use, [[indole]], [[methyl red]] and [[Voges–Proskauer test|Voges-Proskauer tests]].<ref>{{cite journal | vauthors = Closs O, Digranes A | title = Rapid identification of prompt lactose-fermenting genera within the familyh Enterobacteriaceae | journal = Acta Pathologica et Microbiologica Scandinavica, Section B | volume = 79 | issue = 5 | pages = 673–8 |year = 1971 | pmid = 5286215 | doi = 10.1111/j.1699-0463.1971.tb00095.x }}</ref>
