Different genus of bacteria has been reported with the capacity to solubilize phosphorus from phosphate rock (PR). Pseudomonas sp., (A18) and Serratia sp., (C7) isolated from soils at the “ Departamento de Boyacá ” Colombia, where Allium cepa is cultivated. Bacteria were cultured in MT11B media and evaluated as a bio-fertilizer for A. cepa germination and growth during two months at greenhouse scale. Pseudomonas sp., and Serratia sp., cultured at 30 °C, 48 h in SMRS1 agar modified with PR, (as an inorganic source of phosphorus), presented a phosphate solubilization index (SI) of 2.1 ± 0.2 and 2.0 ± 0.3 mm, respectively. During interaction assays no inhibition halos were observed, demonstrating there was no antagonism between them. In MT11B media growth curve (12 h) demonstrated that co-culture can grow in the presence of PR and glucose concentrations 7.5-fold, lower than in SMRS1 media and brewer's yeast hydrolysate; producing phosphatase enzymes with a volumetric activity of 1.3 ± 0.03 PU at 6 h of culture and 0.8 ± 0.04 PU at 12 h. Moreover, co-culture released soluble phosphorus at a rate of 58.1 ± 0.28 mg L −1 at 8 h and 88.1 ± 0.32 mg L −1 at 12 h. After five days of evaluation it was observed that germination percentage was greater than 90 % of total evaluated seeds, when placing them in contact with the co-culture in a concentration of 1 × 10 8 CFU mL −1 . Furthermore, it was demonstrated that co-culture application (10 mL per experimental unit to complete 160 mL in two months) at 8.0 Log 10 CFU mL −1 twice a week for two months increased A. cepa total dry weight (69 ± 13 mg) compared with total dry weight (38 ± 5.0 mg) obtained with the control with water.

“…This indicated that there was no antibiosis, space competition or nutrient competition. 25 Pérez et al 26 isolated 130 strains capable of solubilizing Ca 3 (PO 4 ) 2 . None exhibited FePO 4 -or AlPO 4 -solubilizing activities, and so they are largely impractical for use in acidic soils.…”

BACKGROUND Phosphate‐solubilizing bacteria (PSB) can be an environment‐friendly strategy to improve crop production in low‐phosphorus (P) or P‐deficient soils. The effect of indigenous mixed inocula of PSB on Agave angustifolia Haw. growth was assessed. The four treatments evaluated were T1 (Pseudomonas luteola + Enterobacter sp.), T2 (Pseudomonas luteola + Bacillus sp.), T3 (Pseudomonas luteola + Acinetobacter sp.), and T4 (control); each was replicated 25 times using a completely randomized design during 12 months under rain‐fed conditions. Additionally, P solubilization in vitro of the mixed inocula with three different sources of inorganic P was tested. RESULTS The mixed inocula were able to solubilize more P from tricalcium phosphate Ca3(PO4)2 than from aluminum phosphate (AlPO4) and iron phosphate (FePO4). Relative to the control, T2 increased plant height by 22.9%, leaf dry weight by 391.4%, plant stem diameter by 49.6%, and root dry weight by 193.9%. The stem solid soluble content increased 50.0% with T1. Plant‐available soil P increased 94.6% with T3 and 77.3% with T1. Soil alkaline phosphatase activity increased 85.9% with T1. CONCLUSION T2 was the mixed inoculum that most improved Agave angustifolia plant growth. The indigenous mixed inocula of PSB evaluated appears to be a practical and efficient option for promoting field growth of Agave angustifolia plants. However, further research is necessary to achieve a deeper understanding of the relationships between different PSB species and their effects on agave, which may reveal some of the mechanisms of the synergistic interactions that are involved in the promotion of plant growth. © 2019 Society of Chemical Industry
