Cellulose acetate containing toluidine blue and rose Bengal is an effective microbial coating when exposed to white light

Article Abstract:

Simple methods of reducing the microbial load on surfaces in hospitals are needed to reduce the risk of hospital-associated infections. The ability of a cellulose acetate coating containing the photosensitizers toluidine blue and rose Bengal to kill microbes (Staphylococcus aureus, Escherichia coli, Clostridium difficile, a bacteriophage, and Candida albicans) on its surface when illuminated to white light is presented.

Posttranslational protein modification in Archaea

Article Abstract:

Archaeal systems are examined in order to study the natural pathways and to underscore the similarities between archaeal, eucaryal, and bacterial biology. Archaea has proven to be a valuable resource in the search for new information on posttransitional protein modification.

The acetate switch

Article Abstract:

'Acetate switch' occurs as cells deplete their environment of acetate-producing carbon sources and begin to rely on their ability to scavenge for acetate. The 'acetate switch' as it exists in selected eubacteria, archaea, and eukaryotes including humans is described.
