The major current research effort of our laboratory is the analysis of the regulation of thermotolerance in Salmonella enterica . Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride. ADVERTISEMENTS: The following points highlight the six important groups of extremophiles. Cations and anions are both ions. The Microbiology section is a comprehensive collection of practical methods for designing and implementing successful experiments in microbial research across viruses as well as unicellular and cell-cluster organisms including prokaryotes (bacteria, archaea) and eukaryotes (fungi, protists, microalgae) to study their genetic, biochemical, and biophysical properties.
