TL;DR: Saponin from Quillaja saponaria has a cytotoxic effect at concentrations higher than 25 μg/mL and in the range of 12–50 μg/ mL significantly increases the level of early apoptotic cells, which postulates increases the influx of nutrients from the medium into E. coli cells.

TL;DR: Methods of human bacterial pathogen identification need to be fast, reliable, inexpensive, and time efficient, and these requirements may be met by vibrational spectroscopic techniques.

TL;DR: Pseudomonas aeruginosa strains from a range of clinical and environmental sources were collated into a single reference strain panel to harmonise research on this diverse opportunistic pathogen and may provide a valuable resource for the testing of novel therapies against this problematic pathogen.

TL;DR: It is found that the toxicity of the ionic liquids was strain-dependent, and that they strongly affected the Gram-negative bacterial membrane, causing changes of the zeta potential and membrane lateral diffusion.

TL;DR: The ionic liquids did not interfere with DNA in vitro, and intracellular DNA damage that occurred after treatment was probably caused by lipid peroxidation and oxidative stress.
