Extracellular phytase activity of Bacillus amyloliquefaciens FZB45 contributes to its plant-growth-promoting effect.

Transition state regulator AbrB inhibits transcription of Bacillus amyloliquefaciens FZB45 phytase through binding at two distinct sites located within the extended phyC promoter region.

We have previously identified the phyC gene of Bacillus amyloliquefaciens FZB45, encoding extracellular phytase, as a member of the PhoP regulon, which is expressed only during phosphate starvation. Its sigma(A)-dependent promoter is positively and negatively regulated by the phosphorylated PhoP response regulator in a phosphate-dependent manner (O. Makarewicz, S. Dubrac, T. Msadek, and R. Borr...

Production and biochemical characterization of a thermostable phytase from Bacillus amyloliquefaciens LOR10

Phytase can improve the nutritional value of plant-based foods by enhancing protein digestibility and mineral availability through phytate digestion in the stomach and the food processing industry. Microbial sources are more promising for the production of phytases on a commercial scale. The objectives of this exploration were to screening and isolation of phytase-producing bacteria from hot sp...

Isolation and Characterization of Plant Growth- Promoting Bacillus amyloliquefaciens Strain sks_bnj_1 and its Influence on Rhizosphere Soil Properties and Nutrition of Soybean (Glycine max L. Merrill)

The objective of this work was to isolate and characterize Bacillus bearing multiple plant growthpromoting traits from diseased roots of soybean and to further assess its inoculation effect on soil rhizosphere properties and nutrition in soybean. The isolate was putatively identified as Bacillus on the basis of cultural characteristics and FAMEs profile, and further sequencing of 16S rRNA gene ...
