Phenotypic and Molecular Characterization of the Beetle Pathogens Paenibacillus popilliae and Paenibacillus lentimorbus
… of the strains were determined to be <I>Paenibacillus popilliae</I> and ten were found to be more closely related to <I>Paenibacillus lentimorbus</I>. Only one of the <I>P. popilliae</I> strains, an isolate from Mexico, was resistant to the antibiotic vancomycin, a trait characteristic of …

Production and Characterization of a Novel Extracellular Polysaccharide Produced by Paenibacillus velaei, Sp. Nov
Paenibacillus velaei, sp. nov. is a soil bacterium capable of producing an unusually large amount of exopolysaccharide (EPS). The EPS contains glucose, mannose, galactose and fucose in a molar ratio of 4:2:1:1. The molecular weight of the EPS is higher than 2x106. The viscosity of 1% EPS is 1300 cP …

Fermentative utilization of glycerol and lignocellulosic sugars and production of ethanol by Paenibacillus macerans
With the recent volatility in crude oil prices and widespread concern regarding global warming, there is increased need for finding sustainable alternatives to petrochemical based fuels. One way to achieve this objective is through the production of biofuels such as ethanol by microbial …

Surveillance and improved control of American foulbrood in Saskatchewan honey bees through the detection of Paenibacillus larvae spores in pooled, extracted honey
… endospores (spores) of the causative agent, Paenibacillus larvae, are incredibly resilient to environmental extremes and are impervious to antimicrobials licensed for use against AFB (1–3). Consequently, non-curative antibiotic use fosters dependency and sustained, indiscriminate use to …

Time-of-Flight Secondary Ion Mass Spectrometry Analysis of Microbial Induced Corrosion of Glasses
… of nuclear waste vitrification materials. A Paenibacillus sp. originating near the Hanford site subsurface was investigated as a model biofilm system. Time-of-flight secondary ion mass spectrometry (ToF–SIMS) – a powerful mass spectral imaging technique with high surface sensitivity, mass …

Characteristics of biological control agents and their antagonism against rice pathogens and pests
… 16S rDNA and identified them as Bacillus sp. and Paenibacillus sp. respectively. Microbial volatile compounds have received attention as tools to promote plant growth and suppress pathogens, nematodes and insects. I hypothesized that the chosen bacterial strains (Bacillus sp., Paenibacillus sp. …

Immune Priming in A. Mellifera
… "priming" we inoculated honeybee queens with Paenibacillus larvae (Pl), a spore-forming bacterium causing American Foulbrood, a brood disease that once plagued beekeepers worldwide. Following inoculation, offspring of "primed" queens were fed a diet containing P. larvae spores and mortality …

Potential for probiotics to mitigate environmental stress in Western honey bees
… to Apis mellifera, such as Varroa mites and Paenibacillus larvae. Lactobacilli are part of the honey bee hindgut microbiota, and some probiotic strains have been shown to enhance host immunity and buffer against pathogens. In addition, certain Lactobacillus strains can inhibit P. larvae …

Characterization of diazotrophs containing Mo-independent nitrogenases from diverse natural environments
… related to Citrobacter sp., Klebsiella sp. and Paenibacillus sp., respectively. We were able to clone and sequence Mo-independent nitrogenase genes from these strains. This study also includes a phylogenetic analysis of AnfG and VnfG. In conclusion, we have demonstrated that diazotrophs with …

Identification and Optimization of the Antagonistic Potential of Native Spinach Microbiota towards Escherichia coli O157:H7
… a moderate level of acid. Two of these strains, Paenibacillus polymyxa and Pseudomonas espejiana, were found to secrete a non- protease antagonistic compound. These antagonists varied in their reduction of E.coli O157:H7 numbers in vitro, but all significantly reduced numbers in 48 hours of …

The exploration of potato-associated bacteria in the Central Andean Highlands and their application in integrated crop management systems
… R43631 (Peru), Bacillus sp. R47065, R47131, Paenibacillus sp. B3a R49541, and Bacillus simplex M3-4 R49538 (Ecuador), showed significant increase in the yield of potato. Using – omic technologies (i.e. volatilomic, transcriptomic, proteomic and metabolomic), the influence of microbial …

Development of a functionalized coating for inhibition of marine corrosion and biofouling.
… this study, biologically active microorganisms. Paenibacillus polymyxa biofilms inhibit the corrosion of metal substrates and this strain has the advantage of forming endospores can withstand the solvent and acid concentrations required in sol-gel formulation. Encapsulation of viable P. polymyxa …

Studies on Selected Microbial Biotransformations of Arsenic Compounds
… these isolates are identified to species level {Paenibacillus glucanolyticus and Pseudomonas fluorescens A). With analysis by HPLC-inductively coupled plasma-mass spectrometry (ICP-MS), the degradation of arsenobetaine is described by initial cleavage of the methyl arsenic bond to form …
