title: A simple fluorescence of staining technique for in situ soil microorganisms.
abstract: A simple, rapid straining technique using the magnesium salt of 1-anilino-8-naphthalene sulfonic acid is described. Treatment of soil with an aqueous, membrane-filtered solution (3.5 mg/ml) of the salt causes the soil microorganisms to fluoresce when examined with light from a mercury arc light source.
