The occurrence of garden strawberry grey rot in 2020–2021 over the period harvesting amounted to, on average, 13,9 % and 21,2 respectively. A four time application Serenade ASO, SC biological preparation (Bacillus amyloliquefaciens, strain QST 713) a dose 6,0–8,0 l/ha before held effectively spread disease. In field experiment small plots reduction number infected berries to from 55,4 63,3 %, w...

Microbial levan is an important biopolymer with considerable potential in food and medical applications. Bacillus amyloliquefaciens NK-ΔLP strain can produce high-purity, low-molecular-weight levan, but production is relatively low. To enhance the production of levan, six extracellular protease genes (bpr, epr, mpr, vpr, nprE and aprE), together with the tasA gene (encoding the major biofilm ma...

Harmful algal blooms, caused by massive and exceptional overgrowth of microalgae and cyanobacteria, are a serious environmental problem worldwide : In the present study, we looked for Bacillus strains with sufficiently strong anticyanobacterial activity to be used as biocontrol agents. Among 24 strains, Bacillus amyloliquefaciens FZB42 showed the strongest bactericidal activity against Microcys...

Environmental strain Bacillus amyloliquefaciens FZB42 differs from the domesticated model organism of the same genus, Bacillus subtilis 168, in its ability to promote plant growth and suppress plant-pathogenic organisms present in the rhizosphere. This behavior is exerted mainly through the production of several nonribosomal cyclic lipopeptides and polyketides, which exhibit a broad range of ac...

Bacteria serve as live food and nutrients for bacterial-feeding nematodes (BFNs) in soils, and influence nematodes behavior and physiology through their metabolism. Five bacterial taxa (Bacillus amyloliquefaciens JX1, Variovorax sp. JX14, Bacillus megaterium JX15, Pseudomonas fluorescens Y1 and Escherichia coli OP50) and the typical BFN Caenorhabditis elegans were selected to study the effects ...

Conversion of cellulose into fermentable sugars for ethanol production is currently performed by enzymatic hydrolysis catalyzed by cellulases. The cellulases are produced by a wide variety of microorganisms, playing a major role in the recycling of biomass. The endo-1,4-β-glucanase (CelB31C) from Bacillus amyloliquefaciens B31C, isolated from compost and previously selected on the basis of high...

The neutral protease has high potential for industrial applications, and attempts to improve enzyme expression level have important application values. In the present study, a neutral protease-encoding gene, Banpr, was cloned from Bacillus amyloliquefaciens strain K11, and a genetic manipulation method specific for this difficult-to-transform strain was developed for the high-level expression o...

La producción de orégano es relevancia económica en el noroeste México. Sin embargo, los productores para obtener altos rendimientos recurren a la fertilización química, pero su mal uso, agudiza salinidad. Lippia palmeri crece manera natural suelos áridos, pobres materia orgánica, alta salinidad y temperatura En contexto una agricultura sustentable, microorganismos mantienen fertilidad del suel...
