Bacterial pathogens manipulate host cells to promote pathogen survival and dissemination. In this study, microarray technology was used to identify the genes that are affected by the Vibrio vulnificus quorum-sensing genes, luxS and smcR. By comparing the expression profiles of mouse macrophage cell lines stimulated with either the parent strains or a luxS smcR mutant, differentially expressed g...

Microorganisms play a significant role in bioremediation of heavy metal contaminated soil and wastewater. In this study, heavy metal resistant fungi and bacteria were isolated from the soil samples of an electroplating industry, and the bioaccumulations of Cr(VI) and Ni(II) by these isolates were characterized to evaluate their applicability for heavy metal removal from industrial wastewaters. ...

Compact well settling granules were cultivated for degrading 3.9 kg m -3 d -1 of phenols. Formed granules were studied qualitatively using SEM and it was found that a large number of bacterial types including bacterial rod, cocci, diatoms are dispersed in the extracellular polymeric substance (EPS). Degradation studies show that initially the removal rate of phenol was fast but later on it beco...

Identification of anaerobic ammonium oxidizing (anammox) bacteria by molecular tools aimed at the evaluation of bacterial diversity in autotrophic nitrogen removal systems is limited by the difficulty to design universal primers for the Bacteria domain able to amplify the anammox 16S rRNA genes. A metagenomic analysis (pyrosequencing) of total bacterial diversity including anammox population in...

In the present study, the capability of dried indigenous biomass of Vibrio and Oceanimonas, was assessed and compared for mercury biosorption from aqueous solutions. It was found that both of the biosorbents reached equilibrium after 60 min of contact although the mercury sorption capacity of Vibrio was significantly more. Its sorption capacity increased from 9 to 83 ...

Background: The presence of pharmaceuticals at low concentrations (ng to μg) in the environment has become a hot spot for researchers in the past decades due to the unknown environmental impact and the possible damages they might have to the plantae and fauna present in the aquatic systems, as well as to the other living organisms.Objectives: The aim of t...

BACKGROUND Enteropathogenic (EPEC) and Enteroaggregative (EAEC) E. coli have similar, but distinct clinical symptoms and modes of pathogenesis. Nevertheless when they infect the gastrointestinal tract, it is thought that their flagellin causes IL-8 release leading to neutrophil recruitment and gastroenteritis. However, this may not be the whole story as the effect of bacterial adherence to IEC ...

Kitchen (food waste) was collected from hostels of Cancer Hospital & Research Institute (CHRI), Gwalior’s Mess as feedstock for bio-reactor which works as anaerobic digester system to produce biogas energy. Production of biogas ,used as energy source, will be more cost effective, eco-friendly, cut down on landfill waste, generate a high-quality renewable fuel, and reduce CH4 and CO2 emissions, ...

Textile wastewater (TW) contains toxic pollutants that pose both environmental and human health risks. Reportedly, some of these pollutants, including NO3?, NO2? reactive black 5 (RB-5) dye, can be removed via hydrogen-based denitrification (HD); however, it is still unclear how different factors affect their simultaneous removal. This study aimed to investigate the effect H2 flow rate, spargin...
