Cicera rietinum Increase in fresh weight, dry weight, total soluble sugars and protein contents Increase soil aggregation and biofilm formation [82]
Rhizobium meliloti Tomato EPS with high succinoglycan and galactoglucon [67]
Bacillus sp., (B. licheniformis, B. pumilus, B. coagulans, and B. insolitus) Paenibacillus sp., (P. macerans) Microbacterium sp. Burkholderia cepacia Enterobacter sp. Wheat Rhizospheric soil aggregation Decrease Na+ uptake and root biofilm formation [12]
Pseudomonas anguilliseptica SAW 24 Faba bean Enhance plant height and fresh/dry weight [81]
Rhizobium and Pseudomonas Zea Mays Increase proline production Decrease electrolyte leakage along with maintenance of leaf relative water content and uptake of K+ [106]
Bacillus isolates and Mesorhizobium Cicer arietinum L. (Chickpea) Reduce concentration of Na+ in soil [104]
Azotobacter chroococcum Vicia faba L. Enhanced N, P, and K concentrations, the proline content, RWC%, and the K+/Na+ ratio [99]
Aeromonas spp. SAL-17 and SAL-21 Wheat Increase in leaf proline content, nitrate reductase activity, chlorophyll a/b, stomatal conductance, transpiration rate, root length, and shoot length [108]
Aeromonas hydrophila/caviae MAS765, Bacillus insolitus MAS17, and Bacillus sp. MAS617, MAS620, and MAS820 Wheat Restricted passive flow of Na+ from the roots to stele in wheat crop and large root surface covered with soil [107]
Marinobacter lipolyticus SM19 and B. subtilis subsp. inaquosorum Wheat Shoot and root dry weight Restricted Na+ uptake [94] [83]
Pseudomonas aeruginosa PF07 Hellianthus annuus Enhance Root Adhering Soil to Root Tissue ratio (RAS/RT)) and texture of the soil Increase porosity Improve uptake of nutrients [84]
Enterobacter sp. MN17 and Bacillus sp. MN54 Quinoa (Chenopodium quinoa) Improved plant-water relations [105]
Rhodopseudomonas palustris TN114 and PP803 - Chelate Na +cations from aqueous environment [100]
