Phosphate solubilizing bacteria (PSB) have the potential to enhance phosphate-induced immobilization of metals to remediate contaminated soil. However, there is a limit on the amount of phosphate which can be added to the environment due to the issue of eutrophication. [5]
Phosphate solubilizing rhizobacteria are the most common MHB that aids in phosphorus uptake. [13] The bacteria are involved in this process by releasing phosphate-degrading compounds in the soil to break down organic and inorganic phosphate. [14] As a result, the MHB create a pool of phosphate that the mycorrhiza then use.
The plant, in turn, provides the bacteria with organic compounds made by photosynthesis. This mutually beneficial relationship is true of all of the rhizobia, of which the genus Rhizobium is a typical example. [4] Rhizobium is also capable of solubilizing phosphate. [5]
Phosphate solubilization is the process by which organic acids are secreted into the environment, this lowers the pH and dissolves phosphate bonds therefore leaving the phosphate solubilized. Phosphate-solubilizing bacteria (PBS) (ex. Bacillus subtilis and Bacillus circulans ) are responsible for upwards of 50% of microbial phosphate ...
It can also provide protection against drought and some soil-borne diseases. It has also been shown that to produce a larger quantity of crops, biofertilizers with the ability of nitrogen fixation and phosphorus solubilizing would lead to the greatest possible effect. [23] They advance shoot and root growth of many crops versus control groups. [24]
Rhizobium mongolense is a Gram negative root nodule bacteria, ... Phosphate solubilizing rhizobia originating from Medicago, Melilotus and Trigonella grown in a ...
Kushneria phosphatilytica is a Gram-negative, phosphate-solubilizing, aerobic, rod-shaped, non-endospore-forming, halophilic and motile bacterium from the genus of Kushneria which has been isolated from sediments from the Jimo-Daqiao saltern in China. [1] [2]
Mesorhizobium mediterraneum is a bacterium from the genus Mesorhizobium, which was isolated from root nodule of the Chickpea (Cicer arietinum) in Spain. [4] [5] The species Rhizobium mediterraneum was subsequently transferred to Mesorhizobium mediterraneum. [6]
