Paenibacillus polymyxa

Trends in Microbiology, 2023
Paenibacillus polymyxa Prazmowski (= Bacillus polymyxa) is a Gram-positive, rod shaped, endospore-forming, widely distributed nonpathogenic bacterium with peritrichous flagella. It lives in the rhizosphere and inside plants (i.e., endophytic lifestyle), rarely in marine sediments or fermented foods, and is frequently used against plant, human, and ...

Cytokinin production by Paenibacillus polymyxa

Soil Biology and Biochemistry, 1999
Abstract The production of hormones has been suggested to be one of the mechanisms by which plant growth-promoting rhizobacteria (PGPR) stimulate plant growth. To evaluate whether the free-living soil bacterium, Paenibacillus polymyxa, releases the hormone group cytokinins and, if so, their identity, the content of cytokinins in the growth media ...

Plasmid transduction in Paenibacillus polymyxa

World Journal of Microbiology and Biotechnology, 1999
A previously described soil-isolated Paenibacillus polymyxa bacteriophage named IPy1 was shown to mediate transduction of plasmid DNA. Transductants of strain Loutit containing pC194, pBC16 and pRJ45 were detected at frequencies in the range of 5 × 10−7 to 1.2 × 10−6 per PFU.

Characterization of sporulation histidine kinases of Paenibacillus polymyxa

Research in Microbiology, 2012
Sporulation histidine kinases, which sense sporulation-specific signals and initiate phosphorelay reactions, are poorly conserved among Bacillus species. We found several putative genes for sporulation histidine kinases in the genome sequence of Paenibacillus polymyxa E681 and assayed the genes for complementation of sporulation mutants of Bacillus ...

Comparison of the spores of Paenibacillus polymyxa prepared at different temperatures

Biotechnology Letters, 2012
Paenibacillus polymyxa SQR-21, which is antagonistic against Fusarium oxysporum, is used as a biocontrol agent and, when mixed with organic substances for solid fermentation, produces a bioorganic fertilizer. The spores of P. polymyxa prepared at different temperatures were characterized with respect to the dipicolinic acid content, heat resistance ...

Heat resistance of Paenibacillus polymyxa in relation to pH and acidulants

Journal of Applied Microbiology, 2000
The efficacy of different organic acids in decreasing the heat resistance of Paenibacillus polymyxa spores was assessed. The relationship between concentration of the undissociated form of different organic acids and decrease in heat resistance was also investigated. The heat resistance of P.

Exopolysaccharides of Paenibacillus polymyxa: A review

International Journal of Biological Macromolecules
Paenibacillus polymyxa (P. polymyxa) is a member of the genus Paenibacillus, which is a rod-shaped, spore-forming gram-positive bacterium. P. polymyxa is a source of many metabolically active substances, including polypeptides, volatile organic compounds, phytohormone, hydrolytic enzymes, exopolysaccharide (EPS), etc. Due to the wide range of compounds

Biological activity of silver nanoparticles synthesized with Paenibacillus polymyxa exopolysaccharides

Enzyme and Microbial Technology, 2023
Recently, there has been increased interest in the synthesis of nanoparticles by using natural polysaccharides. These polysaccharides are eco-friendly, nontoxic, and cheap to prepare. On the other hand, the attention in hydrocolloids and films has significantly enhanced, and their application is very promising in the food, pharmaceutical, perfumery and

Paenibacillus polymyxa and Bacillus cereus Concomitant Bacteremia

Infectious Diseases in Clinical Practice, 2019
Abstract The genus Paenibacillus comprised 148 species and are gram-positive, facultative anaerobic, spore-forming, rod-shaped bacteria found in a variety of environments including soil. In the last decade, Paenibacillus polymyxa and its isolates have seen increasing commercial applications in agriculture and medicine.
