Effects of mutation of lolB on extracellular enzyme production in Xcc. The extracellular enzyme activity was evaluated using the substrate-supplemented plate assay as described in the Material and methods section. Values under each photographs are the diameter of hydrolysis zone (in cm) (mean ± standard deviation) from three independent experiments. Different letters following the values indicate significant difference (Student t test, p < 0.05)
