Fermentation of carbohydrates

Fermentation of carbohydrates during the formation of acid can be used to identify bacteria and here is a table of carbohydrates, which are often used for identification, and whether the current bacterium can ferment one or several of them.

Lactose + indicates that the bacterium ferments lactose under acid production.
Note that glucose(gas) - indicates that the bacterium does not ferment glucose under gas formation.

V (or v) means variable, i.e. that some strains of the bacterial species in question ferment carbohydrates, while other strains do not. W (or w) stands for weak, which means that it takes time before the pH change takes place or that the pH change is not so strong.

The revised taxonomy of the mollicutes

The revised taxonomy of mollicutes (mycoplasmas) has now been introduced on VetBact, which means that many of the species have been given new genus names or moved to another higher taxon.
