The wastewater released from distilleries and fermentation industries are the major source of soil and aquatic pollution due to presence of water-soluble recalcitrant colouring compounds called melanoidins. Biological decolourisation of of these compounds found more advantages compared to chemical treatments. Hence in this study, the bacterium Pseudomonas fluorescens showing higher decolorizati...

The fluorescent emission of the thermolyzed Pseudomonas aeruginosa suspensions was measured in order to get a quantitative indicator upon the pyoverdine synthesis – as molecular basis of iron acquisition system of the bacterial cells. The influence of iron ions on the dynamics of pyoverdine was studied by supplying nano-sized iron oxide suspensions in the bacteria culture medium. The stimulator...

a novel podand based anion receptor bearing benzimidazole motifs as recognition sites was designed and synthesized by reaction of 1,7-bis(2'-methylbenzoate)-1,4,7-trioxaheptane and phenylenediamine. the binding properties of anionic guest with this receptor were studied using uv-vis and fluorescence spectroscopy. these studies revealed that this receptor exhibit selective recognition towards f- ...

salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. the present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (nitraria schoberi). thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

A biosensor can sense biological elements after interaction with the recognition element. The signal produced due to interaction of the analyte with its biochemical element is transduced by a transducer and detected by appropriate modes. The miniaturization of these biosensors at the nano level using nanostructures as a platform for sensing the analyte or its detection is called a nanobiosensor...

The specialized proresolution lipid mediator lipoxin A4 (LXA4) is abnormally produced in cystic fibrosis (CF) airways. LXA4 increases the CF airway surface liquid height and stimulates airway epithelial repair and tight junction formation. We report here a protective effect of LXA4 (1 nM) against tight junction disruption caused by Pseudomonas aeruginosa bacterial challenge together with a dela...
