Confocal laser microscopy is seen as a powerful tool for examining structure, organization, and physiology of single biofilm cells in situ. A surface electrochemical phenomenon common to all base metals in aqueous or humid environments whereby metal ions are developed at a cathodic site and the electrons associated with this dissolution accepted at an anodic site. A stain used in fluorescence microscopy that stains membranes of living or dead cells and fluoresces green. A substance that accepts electrons and is reduced during an oxidation-reduction reaction. Compound that donates electrons in an oxidation-reduction reaction.
Examples are organic carbon and hydrogen.
Specimens must be fixed prior to inspection resulting in dehydration of the cells, and possible generation of artifacts within the image. Enzymes display a high degree of specificity with regard to both the substrate on which they act and the type of reaction they catalyze. Enzymes may also be introduced from outside the cell to cause biomedical reactions. Generic term referring to polymers of varying chemical composition that are excreted outside the cell. Synonymous with exopolysaccharide, exocellular polymer, extracellular polymer, and exopolymer.
