Platinum oxide nanoparticles were prepared by a simple hydrothermal route and chemical reduction using carbohydrates (Fructose and sucrose) as the reducing and stabilizing agents. The crystallite size of these nanoparticles was evaluated from X-ray diffraction (XRD), atomic force microscopy (AFM) and transmission electron microscopy (TEM) and was found to be 10 nm as shown in figure 1, which is...
The biodegradability of dispersants (naphthalenesulfonate formaldehyde condensates), used with disperse dyes, has been evaluated using different techniques such as chemical oxygen demand (COD), UV-spectroscopic analysis and tonometry. A biomass was used from industrial waste water which was acclimated for six months prior to use. The study has shown that biodegradation involves two steps: first...
Northern hybridization and S1 nuclease mapping revealed that the amyP gene coding for maltotetraose-forming amylase of Pseudomonas stutzeri MO-19 is transcribed as a monocistronic mRNA of 2.0 kilobases and that the transcription start site is located 81 base pairs upstream from the first nucleotide of the initiation codon. The amyP gene was expressed weakly in Escherichia coli, and transcriptio...
BACKGROUND Autotransporters represent a widespread family of secreted proteins in Gram-negative bacteria. Their seemingly easy secretion mechanism and modular structure make them interesting candidates for cell surface display of heterologous proteins. The most widely applied host organism for this purpose is Escherichia coli. Pseudomonas stutzeri A15 is an interesting candidate host for enviro...
The complexity of the bacterial recombination system is a barrier for the construction of bacterial mutants for the further functional investigation of specific genes. Several protocols have been developed to inactivate genes from the genus Pseudomonas. Those protocols are complicated and time-consuming and mostly do not enable easy construction of multiple knock-ins/outs. The current study des...
Introduction of quinoa (Chenopodium willd.), a gluten-free nutritious pseudo-cereal, outside its traditional growing areas exposed it to seedling damping-off. Here, we isolated eleven phosphate-solubilizing bacteria from the rhizosphere and assessed their effect on germination seedlings growth. All isolates solubilized phosphate, produced indole3-acetic acid, hydrocyanic siderophores, ammonia. ...
The management of municipal solid waste is one of the major problems of the present world. The use of microbial enzymes for sustainable management of the solid waste is the need of the time. In the present study, we have isolated a potent amylase producing strain (ISL B5) from municipal solid waste. The strain was identified as Pseudomonas stutzeri (P. stutzeri) both biochemically and by 16S rD...
Pseudomonas stutzeri A1501, associative and endophytic nitrogen-fixing bacterium showed the capacity of colonization in the rice roots and considered as the good colonizer in the rice plant. The experiment was conducted to study the expression of genes potentiality relevant to the association of nitrogen fixing Pseudomonas stutzeri with host rice and reveal the molecular mechanism by which unde...
Unlike most Pseudomonas, the root-associated bacterium Pseudomonas stutzeri A1501 fixes nitrogen after the horizontal acquisition of a nitrogen-fixing (nif) island. A genome-wide search for small noncoding RNAs (ncRNAs) in P. stutzeri A1501 identified the novel P. stutzeri-specific ncRNA NfiS in the core genome, whose synthesis was significantly induced under nitrogen fixation or sorbitol stres...
Here we present a draft genome of Pseudomonas stutzeri strain KOS6. This strain was isolated from industrial hydrocarbon sludge as a diazotrophic microorganism. It represents one of the major parts of the culturable community of the waste and has potential importance for phytoremediation technology.
