Shape of rhizobium
Did you know?
WebbRhizobia are rod shaped bacteria, 0.8 um in diameter and 2 um in length, often with flagellae. They assume a different shape when inside their host, being irregularly shaped … WebbThe Rhizobiaceae are, like all Pseudomonadota, Gram-negative. They are aerobic, and the cells are usually rod-shaped. [3] Many species of the Rhizobiaceae are diazotrophs …
Rhizobia are a paraphyletic group that fall into two classes of Pseudomonadota—the alphaproteobacteria and betaproteobacteria. As shown below, most belong to the order Hyphomicrobiales, but several rhizobia occur in distinct bacterial orders of the Pseudomonadota. These groups include a variety of non-symbiotic bacteria. For instance, the plant pathogen Agrobacterium is a closer relative of Rhizobium than the Bradyrhizobium that nodulate soybean. WebbThe rhizobial concentration was adjusted to 5 × 10 9 CFU mL −1, starting from the known initial concentration. This was determined by the serial dilution method (10 −4 –10 −5 ), which was cultured in Petri dishes with solid LM medium and incubated for 48 h at 30 °C. An inoculation assay was carried out on river sand previously washed and sieved.

PGPB have shown potential to promote vegetative growth when they are used to inoculate row or horticultural crops [ 58, 59 ].
