In a greenhouse experiment, the nematicidal effect of some bacterial biofertilizers including the nitrogen fixing bacteria (NFB) Paenibacillus polymyxa (four strains), the phosphate solubilizing bacteria (PSB) Bacillus megaterium (three strains) and the potassium solubilizing bacteria (KSB) B. circulans (three strains) were evaluated individually on tomato plants infested with the root-knot nem...

Objective. To investigate the ability of Paenibacillus polymyxa KB to produce biologically active substances that stimulate growth and development plants. Methods. Qualitative quantitative determination auxins, abscisic acid (ABA) cytokinins in culture fluid (CF) P. was carried out by high-performance liquid chromatography (HPLC) using Agilent 1200 chromatograph; gibberellins were measured (HPL...

A Gram-positive, rod-shaped, endospore-forming organism, strain CCUG 47242T, was isolated from a sample of industrial starch production in Sweden. 16S rRNA gene sequence analysis demonstrated that this isolate was moderately related to species of the genus Paenibacillus, with <94.4 % sequence similarity to all other hitherto described Paenibacillus species. Strain CCUG 47242T showed the greates...

Canola (Brassica napus L. var. oleracea) is the third most common oil-producing crop worldwide after palm and soybean. cultivation requires use of chemical fertilizers, but amount required can be reduced by applying plant growth-promoting bacteria (PGPB). Among PGPB, endophytic have certain advantages as biofertilizers, canola rarely been studied. In this work, we identified a collection bacter...

The endospore of Bacillus polymyxa was originally described by Meyer (1897) in a study of a bacillus which he designated Astasia asterospora. Meyer's drawings of the spore, showing ridges and the star shaped aspect, were reproduced by Knaysi (1951) over the name Bacillus asterosporus. It has not been generally recognized that this name is synonymous with B. polymyxa (Smith, et al., 1952). So th...

Isolated from a wide range of sources, the genus Paenibacillus comprises bacterial species relevant to humans, animals, plants, and the environment. Many Paenibacillus species can promote crop growth directly via biological nitrogen fixation, phosphate solubilization, production of the phytohormone indole-3-acetic acid (IAA), and release of siderophores that enable iron acquisition. They can al...

In this study, using high throughput Bpyrosequencing,^ we highlighted the bacterial diversity of the traditional Algerian date product BBtana^ that is produced in southern Algeria using both direct (DBM) and indirect (UBM) methods. Metagenomic analysis yielded a total of 103,379 reads, with a 606 total operational taxonomic units (OTUs) detected. Firmicutes represented 84.79 % of the total pyro...

Метою роботи є огляд нещодавнiх дослiджень генетичних модифiкацiй метаболiзму P. polymyxa для пiдвищення її продуктивностi виробництва 2,3-бутандiолу.&#x0D;
