Gram Negative Chemolithotrophic Bacteria

	Tabular Form of Bacterial Classification From David Bergey's Manual This part has two families Nitrobacteraceae and Siderocapsaceae. Members of the family Nitrobacteraceae are chemolithotrophs and oxidize NH4+ or NO2-, while bacteria belonging to family Siderocapsaceae deposit iron and/or manganese oxide. A third group of organisms metabolizing sulphur and sulphur compounds is also included.
In the family Nitrobacteraceae, cells are rod-shaped, ellipsoidal, spirillar, spherical or lobular. Flagella when present are either subpolar or peritrichous. These bacteria are commonly referred to as nitrifying bacteria and represent a physiological community of morophologically different organisms, both terrestrial and aquatic. Two physiological groups have been recognized. The first which oxidize NH4+ and the second which oxidize nitrite to nitrate. Except in one species namely Nitrobacter winogradskyi which has a polar type of cell growth and multiplies by budding, the others multiply by binary fission
Family Siderocapsaceae includes bacteria which are spherical ellipsoidal or rod shaped. May have thick or thin capsules and are able to deposit iron and/or manganese oxides in or on capsules when present. Mostly found in iron containing waters. The third group (not placed in a family) includes six genera which include bacteria that oxidize sulphur or sulphur compounds, such as Thiobacillus, Sulfolobus, Thiobacterium, Macrotnonas, Thiovulum and Thiospira.
