Gram Negative Anerobic Bacteria

Gram Negative Anerobic Bacteria
Bacteria belonging to this part are pleomorphic, rod shaped, non­motile or motile with peritrichous flagella. Mostly chemoorganotrophs present in natural cavities of man and other animals and intestinal tract of insects. Some are pathogenic. Important members include Bacteriodes, Desulfovibrio and Butyrivibrio.

Members of the genus Desulfovibrio are chemoorganotrophs and obtain energy by anaerobic respiration reducing sulphates or other  reducible sulphur compounds to H2S. These contain C3-cytochromes and desulfoviridin which is responsible for the characteristic red fluorescence at 365 nm
