Rhizobia are bacteria that fix nitrogen (diazotrophs) after becoming established inside root nodules of legumes. To express genes for nitrogen fixation, rhizobia require a plant host; they cannot independently fix nitrogen. In general, they are Gramnegative, motile, nonsporulating rods.

On culture, colonies are round, white, and translucent. Range and environment Edit. The presence of A. vitis has been confirmed in Germany, France, Austria, Hungary, South Africa, and the United States.

Bradyrhizobium is a genus of Gramnegative soil bacteria, many of which fix nitrogen. Nitrogen fixation is an important part of the nitrogen cycle. Plants cannot use atmospheric nitrogen (N 2 ); they must use nitrogen compounds such as nitrates. rhizobium culture wikipedia Dec 05, 2013  Rhizobium is a genus of gramnegative, motile bacteria whose members are most notable for their ability to establish a symbiotic relationship with leguminous plants, such as peas, soybeans, and alfalfa. This relationship leads to the establishment of specialized structures called The Rhizobium culture strains are antigenically very selective and require particular host or nodulation. The surface antigen on the Rhizobial cells recognizes the binding sites (specific root exudates) on the roots of the leguminous plants. This characteristic makes them hostspecific.
