Transgenic expression of glucose dehydrogenase in Azotobacter vinelandii enhances mineral phosphate solubilization and growth of sorghum seedlings
The enzyme quinoprotein glucose dehydrogenase (GDH) catalyses the oxidation of glucose to gluconic acid by direct oxidation in the periplasmic space of several Gram-negative bacteria. Acidification of the external environment with the release of gluconic acid contributes to the solubilization of the inorganic phosphate by biofertilizer strains of the phosphate-solubilizing bacteria. Glucose deh...
متن کاملDerepression of Mineral Phosphate Solubilization Phenotype by Insertional Inactivation of iclR in Klebsiella pneumoniae
The mode of succinate mediated repression of mineral phosphate solubilization and the role of repressor in suppressing phosphate solubilization phenotype of two free-living nitrogen fixing Klebsiella pneumoniae strains was studied. Organic acid mediated mineral phosphate solubilization phenotype of oxalic acid producing Klebsiella pneumoniae SM6 and SM11 were transcriptionally repressed by IclR...
متن کاملBIOTECHNOLOGICALLY RELEVANT ENZYMES AND PROTEINS Expression of chondroitin-4-O-sulfotransferase inEscherichia coli and Pichia pastoris
Chondroitin sulfates are linear sulfated polysaccharides called glycosaminoglycans. They are important nutraceutical and pharmaceutical products that are biosynthesized through the action of chondroitin sulfotransferases on either an unsulfated chondroitin or a dermatan polysaccharide precursor. While the enzymes involved in the biosynthesis of chondroitin sulfates are well known, the cloning e...
متن کاملCharacterization of mineral phosphate solubilization traits from a barley rhizosphere soil functional metagenome
Mineral phosphate solubilization (MPS) microorganisms are important for their provision of orthophosphate anions for plant growth promotion activity in soil. In this study, we applied a functional metagenomic approach to identify this trait directly from the microbiome in barley rhizosphere soil that had not received P fertilizer over a 15-year period. A fosmid system was used to clone the meta...
متن کاملMineral phosphate solubilization activity of gluconacetobacter diazotrophicus under P-limitation and plant root environment
The ability to solubilize insoluble inorganic phosphate compounds by Gluconacetobacter diazotrophicus was studied using different culture approaches. Qualitative plate assays using tricalcium phosphate as the sole P-source showed that G. diazotrophicus produced solubilization only when aldoses were used as the C-source. Extracellular aldose oxidation via a pyrroloquinoline quinone-linked glucos...
