“…The close relationship between P. peoriae and P. polymyxa and P. brasilensis, both species able to produce antimicrobial substances (Kajimura and Kaneda 1997;von der Weid et al 2000von der Weid et al , 2002 was demonstrated genetically and phenotypically. For this reason, we decided to investigate whether strains of P. peoriae also have antimicrobial properties.…”

“…Besides the antagonistic activity, the strain NRRL BD-62 is also able to fix molecular nitrogen (von der Weid et al 2002) and to produce enzymes as proteases and chitinases, suggesting that further studies should be addressed to use P. peoriae strain NRRL BD-62 as a plant growth promoter and/or as a biocontrol agent in field experiments.…”

“…However, no data concerning the role of this species in the rhizosphere have been reported. Previous studies indicated a close relationship between P. peoriae, P. polymyxa and P. brasilensis, also a soil-inhabiting bacterium (von der Weid et al 2002). Several Bacillus and related genera have been tested as potential biological control agents as they produce a range of antibiotics and form resistant spores (Edwards et al 1994).…”

Aims: To investigate the potential antagonistic activity of Paenibacillus peoriae strain NRRL BD-62 against phytopathogenic micro-organisms and to determine the physiological and biochemical characteristics of the antimicrobial compound produced by this strain. Methods and Results: Strain NRRL BD-62 showed a broad inhibition spectrum with activity against various phytopathogenic bacteria and fungi. Physico-chemical characterization of the antimicrobial activity showed that it was stable during heat treatment and was retained even after autoclave at 121°C for 10 min. The compound was also stable after the treatment with organic solvents, hydrolytic enzymes and its activity was preserved at a wide range of pH. The partial purification carried out by Sephadex G25 gel filtration showed two profiles of inhibition against the indicator strains tested, suggesting at least two different substances with distinct molecular weight. Conclusions, Significance and Impact of the Study: This is the first report on the production of antimicrobial substances in P. peoriae. Besides the antimicrobial inhibition capability, the strain NRRL BD-62 is also able to effectively fix molecular nitrogen, and produce chitinases and proteases as well, suggesting that further studies should be addressed to use P. peoriae strain NRRL BD-62 as a plant growth promoter and/or as a biocontrol agent in field experiments.

“…Nitrogen fixation has been described in several species of the genus Paenibacillus (3,4,7,8,9,10,11,12,14,16,17,18,19,20,22,23,24,25), and some of these bacteria are promising candidates for crop inoculation (21). In this work, we obtained the genome sequence of Paenibacillus riograndensis SBR5 T , which, in addition to nitrogen fixation, has shown several plant growth-promoting (PGP) capabilities (1,2).…”

Paenibacillus riograndensis SBR5T , a nitrogen-fixing Gram-positive rhizobacterium isolated from a wheat field in the south of Brazil, has a great potential for agricultural applications due to its plant growth promotion effects. Here we present the draft genome sequence of P. riograndensis SBR5 T . Its 7.37-Mb genome encodes determinants of the diazotrophic lifestyle and plant growth promotion, such as nitrogen fixation, antibiotic resistance, nitrate utilization, and iron uptake. Nitrogen fixation has been described in several species of the genus

“…In addition, it has been shown that the soil type was responsible for this diversity . These studies led to the isolation and description of a new species of Paenibacillus named P. brasilensis (von der Weid et al 2002).…”

This review covers the history on Biological Nitrogen Fixation (BNF) in Graminaceous plants grown in Brazil, and describes research progress made over the last 40 years, most of which was coordinated by Johanna Döbereiner. One notable accomplishment during this period was the discovery of several nitrogen-fixing bacteria such as the rhizospheric (Beijerinckia fluminensis and Azotobacter paspali), associative (Azospirillum lipoferum, A. brasilense, A. amazonense) and the endophytic (Herbaspirillum seropedicae, H. rubrisubalbicans, Gluconacetobacter diazotrophicus, Burkholderia brasilensis and B. tropica). The role of these diazotrophs in association with grasses, mainly with cereal plants, has been studied and a lot of progress has been achieved in the ecological, physiological, biochemical, and genetic aspects. The mechanisms of colonization and infection of the plant tissues are better understood, and the BNF contribution to the soil/plant system has been determined. Inoculation studies with diazotrophs showed that endophytic bacteria have a much higher BNF contribution potential than associative diazotrophs. In addition, it was found that the plant genotype influences the plant/bacteria association. Recent data suggest that more studies should be conducted on the endophytic association to strengthen the BNF potential. The ongoing genome sequencing programs: RIOGENE (Gluconacetobacter diazotrophicus) and GENOPAR (Herbaspirillum seropedicae) reflect the commitment to the BNF study in Brazil and should allow the country to continue in the forefront of research related to the BNF process in Graminaceous plants.
