Studies from Nanyang Technological University Provide New Data on Escherichia coli (Influence of carbon-based nanomaterials on lux-bioreporter Escherichia coli)

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Proteobacteria are presented in a new report. According to news reporting originating in Singapore, Singapore, by NewsRx journalists, research stated, "The cytotoxic effects of carbon-based nanomaterials are evaluated via the induction of luminescent genetically engineered Escherichia coli bacterial cells. Specifically, two engineered E. coil bacteria strains of DPD2794 and TV1061 were incubated with aqueous dispersion of three carbon allotropes (multi-wall carbon nanotubes (MWCNTs), graphene nanosheets and carbon black nanopowders) with different concentrations and the resulting bioluminescence was recorded at 30 degrees C and 25 degrees C, respectively."

The news reporters obtained a quote from the research from Nanyang Technological University, "The corresponding optical density changes of bacterial cells in the presence of various carbon nanomaterials were recorded as well. Based on these results, E. coil DPD2794 bacterial induction responds to a greater degree than E. coil TV1061 bacteria when exposed to various carbon-based nanomaterials."

According to the news reporters, the research concluded: "Finally, the surface morphology of E. coil DPD2794 bacteria cells before and after carbon-based nanomaterials treatment was observed using a field emission scanning electron microscope (FESEM), from which morphological changes from the presence of carbon-based nanomaterials were observed and discussed."
