Hydrophobic gold catalysts have recently proven useful in increasing the efficiency of the aerobic oxidation of hydrocarbons in apolar liquid media. Catalytically active 3nm gold nanoparticles can be dispersed on the surface of commercially available methyl-terminated silica by performing chemical reduction of triphenylphosphine gold(I) chloride in the presence of the support in an ethanol/dichloromethane...
Pyoverdine (PVD) is the major siderophore produced by Pseudomonas aeruginosa for iron acquisition. PvdRT‐OpmQ is an ATP‐dependent efflux pump involved in the secretion of newly synthesized pyoverdine (PVD) and of PVD that has transported and released its iron into the bacterium from the periplasm into the extracellular medium. This iron uptake pathway also involves an outer membrane transporter, FpvA,...
