“…The genus of Chryseobacterium has been widely reported for IAA production and a growth-promoting effect on crops, and most of them were tryptophan-dependent [5,31]. In addition, the genera of Microbacterium (ST25, ST49, ST144, ST43) [25], Arthrobacter (ST7, S21) [32], Variovorax (ST98) [33], Agromyces (ST139) [34], Cellulomonas (ST118) [35], Cupriavidus (ST9) [36], Cellulosimicrobium (ST85) [37] and Ensifer (ST46) [38] were also reported to possess the ability to secrete IAA, while the species V. soli (ST98) and C. biazotea (ST118) were first found to be capable of that in the present study.…”

Root-associated microorganisms, which can be recruited specially by plants to cope with environmental stress under extreme conditions, are one of the major mediators of nutrient exchange between plants and the environment. To obtain more crop-beneficial microbes, rhizosphere bacteria of Désirée potatoes cultivated in poor and alkaline soil have been studied. The screening of 83 strains with incomplete identical 16S rDNA sequences showed that 47 strains produced indole acetic acid (IAA), with contents ranging from 0.2 to 42 mg/L, and seven strains were phosphorus-solubilizing, among which six strains significantly increased the growth rate of potato plants. Thirty-seven strains produced siderophore and four strains were zinc-solubilizing, among which three strains significantly alleviated the chlorosis of potato plants. In all of the isolates, the species Variovorax soli (ST98) and Cellulomonas biazotea (ST118) were first found to possess an IAA-secreting ability; the species Leifsonia aquatica (ST172) and Leifsonia naganoensis (ST177) and the genus Sutcliffiella (ST11) were first discovered to be capable of phosphorus solubilization; the species Chryseobacterium daecheongense (ST32) was the first reported to be capable of zinc solubilization; and the species V. soli (ST98), C. biazotea (ST118) and L. naganoensis (ST177) were first found to be capable of plant growth promotion. The discovery of multiple functional bacteria enriched the resources of plant growth-promoting bacteria and provided a foundation for biofertilizer production to improve soil conditions and crop production.

Wheat is the second most important staple crop grown and consumed worldwide. Temperature fluctuations especially the cold stress during the winter season reduces wheat growth and grain yield. Psychrotolerant plant growth-promoting rhizobacteria (PGPR) may improve plant stress-tolerance in addition to serve as biofertilizer. The present study aimed to isolate and identify PGPR, with the potential to tolerate cold stress for subsequent use in supporting wheat growth under cold stress. Ten psychrotolerant bacteria were isolated from the wheat rhizosphere at 4 °C and tested for their ability to grow at wide range of temperature ranging from −8 °C to 36 °C and multiple plant beneficial traits. All bacteria were able to grow at 4 °C to 32 °C temperature range and solubilized phosphorus except WR23 at 4 °C, whereas all the bacteria solubilized phosphorus at 28 °C. Seven bacteria produced indole-3-acetic acid at 4 °C, whereas all produced indole-3-acetic acid at 28 °C. Seven bacteria showed the ability to fix nitrogen at 4 °C, while all the bacteria fixed nitrogen at 28 °C. Only one bacterium showed the potential to produce cellulase at 4 °C, whereas four bacteria showed the potential to produce cellulase at 28 °C. Seven bacteria produced pectinase at 4 °C, while one bacterium produced pectinase at 28 °C. Only one bacterium solubilized the zinc at 4 °C, whereas six bacteria solubilized the zinc at 28 °C using ZnO as the primary zinc source. Five bacteria solubilized the zinc at 4 °C, while seven bacteria solubilized the zinc at 28 °C using ZnCO3 as the primary zinc source. All the bacteria produced biofilm at 4 °C and 28 °C. In general, we noticed behavior of higher production of plant growth-promoting substances at 28 °C, except pectinase assay. Overall, in vitro testing confirms that microbes perform their inherent properties efficiently at optimum temperatures rather than the low temperatures due to high metabolic rate. Five potential rhizobacteria were selected based on the in vitro testing and evaluated for plant growth-promoting potential on wheat under controlled conditions. WR22 and WR24 significantly improved wheat growth, specifically increasing plant dry weight by 42% and 58%, respectively. 16S rRNA sequence analysis of WR22 showed 99.78% similarity with Cupriavidus campinensis and WR24 showed 99.9% similarity with Enterobacter ludwigii. This is the first report highlighting the association of C. campinensis and E. ludwigii with wheat rhizosphere. These bacteria can serve as potential candidates for biofertilizer to mitigate the chilling effect and improve wheat production after field-testing.

“…We observed that inoculated jack bean plants were more e cient in accumulating Zn in the root system than plants that did not receive inoculation. The presence of bacteria in the soil has likely altered the rhizosphere of plants, modifying the solubility of heavy metals (Boechat et al, 2017;Zheng et al, 2023); however, more targeted studies of the rhizosphere of plants are needed to elucidate the immobilization of metals in roots. Plant-associated bacteria may also have in uenced the Zn translocation in the plant, as they can aid phytoextraction by increasing the transport of heavy metals in plants (Boechat et al, 2017).…”

Metal-polluted soils can pose a severe threat to the environment and need remediation. We assessed the potential of jack bean and mucuna inoculated with rhizobial strains on the phytoremediation of soils contaminated by lead (Pb) smelting activities in Santo Amaro, Bahia state, the most severe case of Pb contamination in Brazil. Plants were grown in pots containing soils with three contamination levels for Pb, cadmium (Cd), and zinc (Zn) based on the distance from the chimney of the abandoned Pb smelter plant. Legumes and inoculated strains were tolerant to soil contamination. The BR 2811 strain is potentially indicated to increase jack bean biomass. The Cd, Pb, and Zn concentrations in plants were highest when grown on the soil with the highest contamination level. We found significant interactions between strains and soil contamination levels for phytoextraction efficiency. However, soil's very high metal contents can make phytoextraction unfeasible due to the time required to bring the metals to regulatory concentrations. The Cd, Pb, and Zn net removal from soil was proportional to increased contamination levels. The legumes did not show potential for Pb phytoextraction, but they have the potential for Zn phytoextraction and Cd phytostabilization. The BR 2811, BR 3501, and BR 7606 strains were the most promising to increase the phytoremediation potential of jack bean and mucuna.
