“…Variations in the frequency of isolates of rhizospheric bacteria observed among different legumes are likely due to the unique root exudate profile of each plant. These profiles attract distinct microbial communities, turning the rhizosphere into an “exclusive” zone of feeding and interaction that influences plant growth [ 30 ]. This work constitutes the first report on the isolation of rhizospheric bacteria capable of solubilizing insoluble phosphates from the rhizosphere of cover legumes in degraded acidic soils of the tropical region of Peru.…”

Due to its adsorption with aluminum and iron hydroxides, phosphorus viability is low in acidic soils; thus, the aim of this study was to isolate and identify bacteria from the rhizosphere of four legumes growing in acidic soils of the Cumbaza Sub-basin, San Martín, Peru, as well as to characterize their ability to solubilize aluminum phosphate and iron phosphate. The isolation process was conducted on TSA medium and the isolates were classified based on their origin and morphocolonial characteristics, with the bacillary shape being the most frequent, followed by cocci. To assess the solubilization of aluminum and iron phosphates, the liquid medium GELP was employed. Sixteen strains were selected, among which three stood out for their effectiveness in solubilizing AlPO4 (Sfcv-098-02, 22.65 mg L−1; Sfc-093-04, 26.50 mg L−1; and Sfcv-041-01-2, 55.98 mg L−1) and one for its ability to solubilize FePO4 (Sfcr-043-02, 32.61 mg L−1). These four strains were molecularly characterized, being identified as Enterobacter sp., Pseudomonas sp., and Staphylococcus sp. Additionally, a decrease in pH was observed in the reactions, with values ranging from 5.23 to 3.29, which enhanced the phosphate of solubilization. This suggests that the selected bacteria could be used to improve phosphorus availability in agricultural soils.

“…Rhizosphere engineering, an increasingly popular field of research, strives to comprehend and regulate plant and microbial interactions in order to boost plant growth, productivity in agriculture, and sustainability concerns ( Ahkami et al., 2017 ). New approaches are being developed to solve the worldwide food crisis and promote sustainable agricultural practices by leveraging the power of the rhizosphere ( Sharma et al., 2021 ) ( Figure 1 ). Plant-microbe interactions in the rhizosphere are relatively complex and mutually beneficial ( Schenk et al., 2012 ).…”

Turmeric (Curcuma longa L.), a significant commercial crop of the Indian subcontinent is widely used as a condiment, natural dye, and as a cure for different ailments. Various bioactive compounds such as turmerones and curcuminoids have been isolated from C. longa that have shown remarkable medicinal activity against various ailments. However, reduced soil fertility, climatic variations, rapid urbanization, and enhanced food demand, pose a multifaceted challenge to the current agricultural practices of C. longa. Plant growth-promoting microbes play a vital role in plant growth and development by regulating primary and secondary metabolite production. Rhizospheric associations are complex species-specific interconnections of different microbiota with a plant that sustain soil health and promote plant growth through nutrient acquisition, nitrogen fixation, phosphate availability, phytohormone production, and antimicrobial activities. An elaborative study of microbiota associated with the roots of C. longa is essential for rhizospheric engineering as there is a huge potential to develop novel products based on microbial consortium formulations and elicitors to improve plant health, stress tolerance, and the production of secondary metabolites such as curcumin. Primarily, the purpose of this review is to implicate the rhizospheric microbial flora as probiotics influencing overall C. longa health, development, and survival for an increase in biomass, enhanced yield of secondary metabolites, and sustainable crop production.
