“…The limited bioavailability of phosphorus in the soil limits agricultural productivity requiring replacing this element to meet the needs of the crops. However, in contact with soil, a percentage of the bioavailable phosphorus is immobilized by sorption and precipitation (AWAIS et al, 2017;LI. ;WHELAN, 2018).…”

Isolation of phosphate-solubilizing bacteria from subtropical soils with different fertilization histories

Phosphorus is one of the most abundant chemical elements but has a low bioavailability index. Therefore, microrganisms play a fundamental role in providing insoluble phosphorus to plants. The objective of this study was to evaluate the capacity of bacteria to solubilize inorganic phosphates in soils with different fertilization histories. Soil and rhizosphere samples were collected from a Red Distroferric Latosol, including a control without mineral or organic fertilizer (C), treatment with mineral fertilizer (MF) according to the needs of each crop, and treatment with organic fertilizer [300 m3 ha-1 of swine wastewater (SW)]. The medium containing calcium phytate presented more colony-forming units (CFU) for all fertilization histories, and growth in treatments C and MF was 50% higher than treatment with SW. CFU values in soils treated with SW were lower than those in the other treatments, and the diversity of insoluble phosphate-solubilizing bacteria (PSB) was higher in treatment C. These results indicate a negative relationship between phosphorus concentrations and the number of PSB.

“…An evaluation of potential phosphate solubilizers of 20 rice root isolates, grown in the Brazilian savanna region, verified that 75% presented solubilizing ability in Pikovskaya medium, and the 16S rRNA gene sequencing analysis revealed that all evaluated isolates showed high similarity with the Bacillus genus (Braga et al, 2018). Phosphorus solubilizing activity is determined by the microbial ability to produce and release organic acids, which through their carboxylic groups chelate the cations bound to phosphorus or decrease the pH, converting phosphorus into soluble forms (Gupta et al, 2012;Awais et al, 2017). Chen et al(2006) used high performance liquid chromatography (HPLC) analysis to detect citric, gluconic, lactic, succinic, propionic acid and three other unknown organic acids produced from the culture of Bacillus, Rhodococcus, Arthobacter, Serratia, Chryseobacterium, Delftia, Gordonia and Phyllombacterium.…”

Beneficial bacteria belong to a group of microorganisms that are able to enhance plant growth by several mechanisms. In this study, phosphorus and zinc solubilizing, nitrogen-fixing and indole acetic acid (IAA) producing bacteria associated with C. brasiliensis were screened to develop microbial inoculants (MI) for use in agriculture. Characterization and identification of screened bacteria were also performed. A total of thirty-one nitrogen-fixing bacteria isolates were obtained, of which 28 showed the ability to solubilize phosphorus and 25 to solubilize zinc. The isolate AP-JNFb-3-2, belonging to the genus Pseudomonas, presented the highest value of solubilized phosphorus (100.4 µg mL-1). The isolates AP-JNFb-3-2 and RHI-JMVL-3-1, associated with the genera Pseudomonas and Enterobacter, respectively, showed the highest values for zinc solubilization (147.8 and 147.7 µg mL-1). Isolate RO-LGI.P-3-2, belonging to the genus Pseudomonas, was the most promising for IAA production (0.52 µg mL-1). The results obtained showed the presence of a large diversity of beneficial bacteria associated with C. brasiliensis, which may be explored as MI in agriculture.

“…The four isolates showed different ability in solubilizing phosphate as shown in Table 2. The formation of halo zones around colonies indicated the synthesis of extracellular organic acids which are able to bind ion Ca 3+ bound into insoluble form of Ca 3 (PO 4 ) 2 and free the ion H 2 PO 4 , forming a more clear zone than surrounding zone with bound P element in agar medium (Awais et al, 2017). Another mechanism to solubilize bound P element is by producing extracellular phosphatase that enzymatically hydrolyze P from its bound compounds (Parhamfar et al, 2016).…”

One problem faced by chrysant farmer in North sumatera, indonesia is to control fungal disease caused by Fusarium oxysproum. The aims of this study were to know antagonistic bacterial isolates to reduce fungal disease caused by F. oxysporum and to know the isolates ability in producing plant growth hormon such as indole acetic acid and in solubilizing phosphate. Eight bacterial strains, collection of laboratory of Microbiology, Universitas sumatera Utara were tested against F. oxysporum in dual culture assay. two bacterial isolates, sP1, closely related to Bacillus amyloliquefaciens strain MPA 1034 and sP7R, closely related to Pseudomonas versuta strain l10.10 showed to reduce fusarium wilt in chrysant along with production of indole acetic acid and phosphate solubilizing properties in vitro. Application of the two antagonistic bacterial isolates resulted in considerably decrease of disease intensity caused by F. oxysporum. The results showed that utilization of bacterial isolate to promote chrysant performance is promising in the next future.
