Application
Magnesium sulfate heptahydrate can be used as a catalyst to synthesize tri/tetra-substituted imidazoles via a one-pot condensation reaction of aromatic aldehydes, benzil, aliphatic and aromatic primary amines, and ammonium acetate. It is also used to synthesize phenazine and quinoxaline derivatives.

Most bacterial species encompass strains with vastly different gene content. Strain diversity in microbial communities is therefore considered to be of functional importance. Yet little is known about the extent to which related microbial communities differ in diversity at this
