Bacillus amyloliquefaciens is a plant-beneficial Gram-positive bacterium involved in suppressing soil-borne pathogens through the secretion of secondary metabolites and high rhizosphere competence. Biofilm formation is regarded as a prerequisite for high rhizosphere competence. In this work, we show that plant extracts affect the chemotaxis and biofilm formation of B. amyloliquefaciens SQY 162 ...
Aqueous two-phase (ATP) systems are useful in the separation of, particularly, biomolecules. These form when an aqueous solution’s concentrations of phase-forming compounds (such as polymers like polyethylene glycol and salts) within envelope. Various physical chemical conditions affect ATP phase formation, such temperature, pH, composition. One set chemicals which has not been characterized te...
Abstract Separating amphiphilic compounds from complex matrix is challenging. Surfactin, cyclic lipopeptides group, was used as a model to find the proper separation conditions and parameters. The aim of work solve emulsification plug problem in countercurrent partition chromatography (CPC). selected solvent system composition n -heptane/ -butanol/methanol/aqueous buffer (20 mM disodium phospha...
The environmental strain Bacillus amyloliquefaciens FZB42 promotes plant growth and suppresses plant pathogenic organisms present in the rhizosphere. We sampled sequenced the genome of FZB42 and identified 2,947 genes with >50% identity on the amino acid level to the corresponding genes of Bacillus subtilis 168. Six large gene clusters encoding nonribosomal peptide synthetases (NRPS) and polyke...
