Phosphate solubilizing bacteria (PSB) have the potential to enhance phosphateinduced 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.
The synergistic interaction between arbuscular mycorrhizal fungi (AMF) and phosphate solubilizing bacteria (PSB) can enhance growth and phosphorous uptake in plants. Since PSBs are well known hyphal colonizers we sought to understand this physical interaction and exploit it in order to design strategies for the application of a combined ...
Phosphate solubilizing PGPR are included in the genera Arthrobacter, Bacillus, Beijerinckia, Burkholderia, Enterobacter, Microbacterium Pseudomonas, Erwinia, Rhizobium, Mesorhizobium, Flavobacterium, Rhodococcus, and Serratia and have attracted the attention of agriculturists as soil inoculate improve plant growth and yield (Oteino et al., 2015 ...
Phosphatesolubilizing bacteria (PSB) can convert insoluble rhizosphere phosphorus into forms that are absorbable by plants and thus enhance the growth of plants. Safflower is a cash crop that is a source of vegetable oils, food coloring and flavoring agents.
Jun 05, 2020· As important plant growthpromoting rhizobacteria, phosphatesolubilizing bacteria (PSB) fix nitrogen, dissolve potassium, promote growth, improve the soil microenvironment, and enhance soil fertility. A highefficiency PSB strain from the pine tree rhizosphere, Burkholderia multivorans WSFJ9, was screened in our laboratory. In this study, using a Bio Screener fully .

Phosphate solubilizing bacteria and their role in plant growth promotion. Biotchnol Adv. 1999; 17:319–339. doi: /S(99)000142.
The purpose of this study was to evaluate the capability of Aspergillus tubingensis and Talaromyces islandicus to solubilize inorganic phosphorus sources, their activity under abiotic stress, and the enhancement of P availability in soils and plant growth. The Psolubilizing capability and acidification mechanism of the strains were assessed in vitro using tricalcium phosphate and rock phosphate.
A biologically pure phosphate solubilizing plant growth promoting rhizobacteria (PGPR) XSB375 was isolated from canola rhizosphere and identified as Bacillus firmus is provided herein. The PGPR is capable to solubilize phosphate that enhance plant available phosphorous. The PGPR XSB375 enhances seed germination, early emergence, plant vigor, root and shoot growth, and higher crop yield.
Jun 01, 2017· The objective of this study was to investigate the ability of three phosphatesolubilizing bacteria (PSB), including Pantoea ananatis (), Rahnella aquatilis and Enterobacter sp. (), to release potassium (K) from mica and also to evaluate their effect in promoting the growth of rice (cv. ''Tarom Hashemi'') plants at an early stage of development.. These isolates .

phosphate was most effective in promoting the growth of sorghum seedlings over 4 weeks. Discussion The use of phosphatesolubilizing bacteria as inoculants increases both phosphorus uptake by the plant and crop yield. Azotobacters are routinely used as freeliving nitrogenfixing inoculants in agriculture and horticulture.
environmental pollution and increase the yield of tea oil. Keywords: phosphate solubilizing bacteria; nutrition; oil tea 1. Introduction Phosphorus (P) is an essential nutrient for plant growth and development. Although a large amount of P is present in soil, the majority of it is unavailable to plants [1]. In agroforestry practices,
