A simple turbidimetric method for specific measurement of Staphylococcus aureus lipase activity.

We have developed a simple semiquantitative method for measuring Staphylococcus aureus lipase activity. Enzymatic activity is measured as the decrease in spectrophotometric absorbancy in a lipid emulsion after incubation with the sample. The sensitivity, precision and accuracy are adequate for routine purposes. The assay is rapid and simple and does not require advanced technical equipment.
