Paenibacillus polymyxa has widely been studied as a model of plant-growth promoting rhizobacteria (PGPR). Here, the genome sequences of 9 P. polymyxa strains, together with 26 other sequenced Paenibacillus spp., were comparatively studied. Phylogenetic analysis of the concatenated 244 single-copy core genes suggests that the 9 P. polymyxa strains and 5 other Paenibacillus spp., isolated from di...

Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

Paenibacillus polymyxa is a potential strain for (R,R)-2,3-butanediol production. Here, we report an annotated draft genome sequence of P. polymyxa strain ATCC 12321, which contains 4,429 protein-coding genes and 49 structural RNAs. This genome sequence provides a genetic basis for a better understanding of the mechanism for the accumulation of highly optically active (R,R)-2,3-butanediol.

Magnetic susceptibility and proton magnetic resonance spectra are reported for the oxidized and reduced forms of the iron-sulfur protein Bacillus polymyxa ferredoxin I. The magnetic susceptibility of the oxidized form indicates antiferromagnetic exchange coupling between component iron atoms that is quantitatively similar to that observed for the clostridial ferredoxins and for the [(C(2)H(5))(...

Waksman and Woodruff (Proc. Soc. Exptl. Biol. Med. 40, 207) listed Aerobcillus polymyxa among the organisms inhibited by streptothricin. This organism produces 2,3-butylene glycol and other solvents from carbohydrates. As mutations may affect the distribution of the fermentation products, it was thought that the fermentations of streptothricin-resistant cultures might be different from those of...

Here we report the draft genome sequence of an endophytic Paenibacillus tyrfis strain isolated from the Universiti Kebangsaan Malaysia reserve forest, Malaysia. The genome size was approximately 8.04 Mb, and the assembly consisted of 107 scaffolds with 168 contigs, and had a G + C content of 53%. Phylogenetic analysis of strain SUK123 using the 16S rRNA gene revealed that it belonged to the fam...

Paenibacillus polymyxa strain EBL06 is a plant growth-promoting bacterium with high antifungal activity. The estimated genome of this strain is 5.68 Mb in size and harbors 4,792 coding sequences (CDSs).

Paenibacillus polymyxa WLY78 is a nitrogen fixer and it can be potentially applied to biofertilizer in agriculture. In this study, P. polymyxa WLY78 is labelled with gfp gene. The GFP-labelled P. polymyxa WLY78 is used to inoculate wheat, maize and cucumber seedlings grown in the gnotobiotic system and in soil, respectively. Observation by confocal laser scanning microscope reveals that the GFP...

While chiral 2,3-Butanediol (2,3-BD) is currently receiving remarkable attention because of its numerous industrial applications in the synthetic rubber, bioplastics, cosmetics, and flavor industries, 2,3-BD-mediated feedback inhibition of Paenibacillus polymyxa DSM 365 limits the accumulation of higher concentrations of 2,3-BD in the bioreactor during fermentation. The Box-Behnken design, Plac...

In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hyd...
