“…Studies dealing with the mobilization of insoluble phosphates by PSM in harsh environments have been conducted by only a few research groups (Goldstein et al, 1999;Johri et al, 1999;Va´zquez et al, 2000;Puente et al, 2004;Son et al, 2006). However, to our knowledge no studies concerning this topic have been conducted in ferriciron-rich, acidic and P-deficient soils, despite the fact that almost 80% of tropical soils in Latin America share these characteristics (Lo´pez-Herna´ndez, 1977).…”

With the aim to explore the possible role of mineral phosphate-solubilizing bacteria (PSB) in phosphorus (P) cycling in iron-rich, acidic soils, we conducted a survey of PSB naturally colonizing a limonitic crust in the south-east region of Venezuela (Bolı´var State). A total of 130 heterotrophic bacterial isolates showing different degrees of mineral tri-calcium phosphate (Ca 3 (PO 4 ) 2 )-solubilizing activities were isolated from NBRIP plates. In contrast, no isolates showing iron phosphate (FePO 4 )-or aluminum phosphate (AlPO 4 )-solubilizing activities were detected by this experimental approach. The 10 best Ca 3 (PO 4 ) 2 -solubilizers were selected for further characterization. These isolates were shown to belong to the genera Burkholderia, Serratia, Ralstonia and Pantoea by partial sequencing analysis of their respective 16S rRNA genes. All the PSB isolates were able to mediate almost complete solubilization of Ca 3 (PO 4 ) 2 in liquid cultures; in contrast, the PSB isolates were less effective when solubilizing FePO 4 . Two groups of PSB isolates were clearly differentiated on the basis of their Ca 3 (PO 4 ) 2 solubilization kinetics. Acidification of culture supernatants seemed to be the main mechanism for P solubilization. Indeed, gluconic acid was shown to be present in the supernatant of five isolates. Furthermore, detection of genes involved in the production of this organic acid was possible in three isolates by means of a PCR protocol. r

Phosphates solubilizing bacterial strains belong to Pantoea, Burkholderia and Enterobacter were isolated and employed in assessing their solubilization ability of Ca phosphate and ER phosphate (Eppawala Rock Phosphate). Among the bacterial strains used, PSB-13 (Pantoea rodasii) showed higher Ca-phosphate solubilization (1100 µg ml -1 ) as well as rock phosphate solubilization (168 µg ml -1 ). The strain was then immobilized in agar to further assess its phosphate solubilization ability. According to the results, agar encapsulated strain solubilized 0.3%, 7.31%, 20.24%, and 20.62% more Ca-phosphate and 11.53%, 15.29%, 28.48%, 36.55% (respectively in 4 cycles) more ER-phosphate than free cells. The reuse efficiency of agar entrapped bacterial cells for Ca-phosphate and ER-phosphate solubilization was greater than that by freely suspended bacterial cells. In conclusion, immobilization could enhance the phosphate solubilization capacity of the strains and thus could be used effectively in enhancing solubilization of ER phosphate.Key words: Pantoea rodasii, Immobilization, Phosphate solubilization, Eppawala rock phosphate

Palabras clave: solubilización de fosfatos, producción de auxinas, microorganismos, crecimiento de plántula, Serratia RESUMENEn el cultivo de chile se usan altas dosis de fertilizantes que al no ser aprovechadas totalmente por las plantas ejercen efectos negativos en el ambiente. El uso de microorganismos benéficos puede ser una alternativa para disminuir las dosis de fertilizantes. En el presente trabajo se aislaron cepas de rizobacterias de la región de la Sierra Nevada, Puebla, México, con el objetivo de evaluar su potencial para promover el crecimiento de plántulas en chile poblano. Las cepas se caracterizaron por su capacidad de solubilizar fosfatos, fijar nitrógeno y producir auxinas. Las diez mejores cepas se evaluaron por su capacidad de promover el crecimiento en plántulas de chile poblano y finalmente éstas se identificaron a nivel molecular. Se aislaron un total de 215 cepas, de las cuales 74 fueron solubilizadoras de fosfatos que liberaron entre 10 y 881 µg/mL de fosfato soluble, 70 cepas tuvieron habilidad de crecer en medio libre de nitrógeno y 71 cepas produjeron entre 20 y 27 µg/mL de indoles. Las cepas inoculadas causaron efecto significativo en el crecimiento (Tukey, p < 0.05), siendo las mejores Serratia plymuthica CPPC55 y Rhizobium nepotum CPAC35, que incrementaron el peso de la parte aérea en más de 20 %. Ambas cepas pueden ser usadas para aumentar la calidad de plántulas de chile poblano, lo cual podría garantizar un mejor establecimiento y sanidad de éstas en campo. Las áreas cultivadas de chile poblano son una fuente de microorganismos que pueden ser utilizados como promotores del crecimiento en especies de importancia agrícola.Key words: phosphate solubilization, auxin production, soil microorganisms, seedling growth, Serratia ABSTRACTThe use of high doses of fertilizers is common in chilli pepper grown, which if are not fully utilized by plants, exerts negative effects on the environment.
