“…In addition to organic acids, certain PSMs can also produce phosphatases, which are significantly involved in phosphorus metabolism [16]. Currently, PSMs are widely employed to improve agricultural yields in a range of crops, such as wheat [15], soybeans [17], peanuts, and mung beans [18].…”

Phosphorus is one of the main nutrients necessary for plant growth and development. Phosphorus-dissolving microorganisms may convert insoluble phosphorus in soil into available phosphorus that plants can easily absorb and utilize. In this study, four phosphorus-solubilizing fungi (L3, L4, L5, and L12) were isolated from the rhizosphere soil of a poplar plantation in Dongtai, Jiangsu Province, China. Phylogenetic analysis based on the internal transcribed spacer (ITS) and large subunit (LSU) of the ribosomal DNA sequences showed that the ITS and 28S sequences of isolates were the most similar to those of Mortierella. Morphological observation showed that most colonies grew in concentric circles and produced spores under different culture conditions. These results and further microscopic observations showed that these isolated fungi belonged to the genus Mortierella. Pikovskaya (PKO) medium, in which tricalcium phosphate was the sole phosphorus source, was used to screen strain L4 with the best phosphorus-solubilizing effect for further study. When the carbon source was glucose, the nitrogen source was ammonium chloride, the pH was 5, and the available phosphorus content was the highest. By exploring the possible mechanism of phosphorus release by phosphorus-solubilizing fungi, it was found that strain L4 produces several organic acids, such as oxalic acid, lactic acid, acetic acid, succinic acid, tartaric acid, malic acid, and citric acid. At 24 h, the alkaline phosphatase and acid phosphatase activities reached 154.72 mol/(L·h) and 120.99 mol/(L·h), respectively.

“…The rhizosphere soil samples were collected at 10 -15cm depth of different medicinal plants from the dry deciduous forest of the Western Ghats regions of Shivamogga District. The collected soil samples were brought into the laboratory in sterile polythene bags aseptically and maintained at 4ºC for further use (Lokesh et al 2016;Chatli et al 2008).…”

In the present study, the phosphate-solubilizing fungus was isolated and identified as Aspergillus niger. Its 18S rRNA gene sequence was deposited at GenBank, NCBI (MN904862). For the study of the Phosphate solubilization capacity of the fungus, different rhizosphere soil samples were collected from medicinal plants. 40 fungal colonies were isolated after serial dilution and one fungal colony with high phosphate solubilization zone was selected and further tested. The fungus showed good results in different phosphate solubilization tests, SI (3.91), SE (290), and pH of the culture filtrate after the growth of the fungus decreased from 6.89 to 3.13 due to the production of organic acids. The colour changed from blue to yellow on the agar plate and red to yellow in the broth due to the acidic condition of the media during the growth of the fungus. Titrable acidity was measured at 32.8g/L and 420µg of P was estimated in culture broth by the Vanadomolybdate method. The fungus showed a positive result for siderophore production. 20µg of Indole Acetic Acid (IAA) was produced by the fungus and was estimated by the Salkowaski reagent method using a standard calibration curve. Due to the phosphate solubilization capacity and production of plant growth promoters of A. niger, can be recommended as a Phosphate solubilizer in an agricultural field.
