A method for identifying a protease secretion deficient strain of a microorganism involves producing a mutant of the microorganism, followed by adding the mutant to gel-filled wells of a microtitration plate, incubating the mutant in the gel-filled wells under conditions call sing the mutant to secrete proteins, separating the mutant from the gel, and measuring activity of a secretion protease of the microorganism in the gel, wherein either (i) the gel is a substrate for the secretion protease or (ii) the gel contains a substrate for the secretion protease.
