“…Considering the threat that herbicide adversely affects the production of legumes on one hand and herbicide tolerant soil microflora may enhance the legume production even under herbicide stressed soil, on the other hand, the current research was designed. Although, B. cepacia is a known pathogen, yet, it also has some agronomic importance and have previously been used as a PGPR due largely to its nitrogen fixing, phosphate solubilizing and ACC deaminase activity (Sandanakirouchenane et al 2017;Rahman et al 2017;Arthee and Marimuthu 2017) for enhancing the production of crops. For instance, B. cepacia as biofertilizer have been applied to protect crops from damaging impact of fungal pathogens leading eventually to the increase in crop yields (Holmes et al 1998).…”

In this study, strain PSBB1 isolated from rhizosphere was identified as, by 16S rDNA sequence analysis and characterized. Strain PSBB1 tolerated glyphosate up to 3200 μg ml and produced IAA (81.6 μg ml), ACC deaminase (69.3 mg protein h), SA (39.3 μg ml) and 2,3-DHBA (26.6 μg ml), solubilized insoluble P (50.8 μg ml) and secreted 29.4 μg ml exopolysaccharides, which decreased with increasing concentrations of glyphosate. Cell damage following glyphosate application was visible under SEM and CLSM. The phytotoxicity of glyphosate on chickpea was variable but significant. . mitigated toxicity and enhanced the size, dry matter, symbiosis, seed attributes and nutritional contents of chickpea. Further, strain PSBB1 declined the levels of CAT, POD, APX and GPX and MDA contents at 4332 μg kg soil glyphosate. Proline also increased under glyphosate stress but declined in inoculated plants. The ability to tolerate higher concentration of glyphosate, the capacity to secrete plant growth regulators even under herbicide stress and potential to reduce the level of proline and antioxidant enzymes makes as an interesting choice for enhancing chickpea production in soils contaminated even with herbicides.

“…Tagele et al (2018) showed that Burkholderia contaminans isolated from rhizospheric soil of maize in South Korea can also produce ammonia (Tagele et al, 2018). Different species of the Burkholderia genera isolated from rice, sugarcane, maize, and black gram also produce ammonia (Paungfoo-Lonhienne et al, 2014;Van and Cao, 2014;Sandanakirouchenane et al, 2017). These studies confirm the capacity for ammonia production among Burkholderia genera with respect to different plant species.…”

Aims: Endophytic bacteria (EB) living inside plant tissues possess different beneficial traits including siderophore production and other plant growth-promoting (PGP) activities. Siderophore-producing EB promote host plant growth by secreting ferrum in iron-deficient conditions. This study screened 19 siderophore producers in vitro, isolated from upland rice roots grown in mountain farms of Tung Village, Nậm Có Commune, Mù Cang Chải District, Yên Bái Province, Vietnam, for PGP traits, including phosphate solubilisation, indole-3-acetic acid (IAA), ammonia, gelatinase, amylase and catalase production. Methodology and results:The bacteria were identified by Matrix assisted Laser Desorption Ionization Time of Flight mass spectrometry (MALDI-TOF MS). All 19 isolates were identified as genera Pseudomonas, Enterobacter, Pantoe, Bacillus, Burkholderia, Staphylococcus, Ralstonia and Cronotacter. The isolates produced catalase and ammonia. The amount of ammonia ranged from 60.74 ± 0.14 to 466.72 ± 0.18 mg/L. Out of the 19 siderophore producers, 17 (89.47%) were able to solubilise phosphate with solubilisation index (PSI) ranging from 1.12 ± 0.07 to 2.14 ± 0.15. The qualitative assays identified 12 isolates (63.15%) positive for IAA production with a tryptophan concentration of 5 mM, whereas 15 (78.94%) and 17 (89.47%) isolates were positive for gelatin and starch hydrolysis, respectively. Especially, 7 isolates were found to be positive for all tested assays in vitro including Pseudomonas rhodesiae (NC2), Enterobacter asburiae (NC50), Pantoea ananatis (NC63), Bacillus cereus (NC64), Burkholderia cenocepacia (NC110), Staphylococcus sciuri (NC112) and Ralstonia pickettii (NC122). Conclusion, significance and impact of study:This study serves as crucial findings of multi-trait plant growthpromoting endophytic bacteria isolated from upland rice root in north-western Vietnam. The seven potential isolates positive for all tested assays could be effective PGP bacteria for bio-inoculants.

“…To date the virulent capacity of B. ubonensis has not been demonstrated (Price et al, 2017) and B. vietnamiensis is frequently isolated as diazotrophic bacterial in different cultures (Govindarajan et al, 2008;Tang et al, 2010;Shinjo et al, 2018). Authors such as Baldani et al (2000), Prasertsincharoen et al (2015) and Sandanakirouchenane et al (2017), reported the promotion of rice growth through the inoculation of rhizospheric diazotrophic strains of B. vietnamiensis. Although diazotrophy is intrinsic in B. vietnamiensis (Eberl and Vandamme, 2016), B. ubonensis la3c3 was able to reduce ethylene in acetylene, its diazotrophic capacity being reported for the first time.…”
