Soil quality. Measurement of enzyme activity patterns in soil samples using fluorogenic substrates in micro-well platesWhat is this ISO TS 22939 Fluorogenic substrates in micro well plates in soil quality about? ISO TS 22939 discusses soil quality with a focus on the measurement of enzyme activity patterns in soil samples. ISO TS 22939 specifies a method for the measurement of several enzyme activities (arylsulfatase, glucosidase, glucosidase, Cellubisidase, Xylosidase, phosphodiesterase (PDE), chitinase, phosphomonoesterase (PME), leucine aminopeptidase, Alanine
