Pectinase activity in plate assays using extracellular proteins secreted by different strains. The activity was determined at 4 to 37 °C and at pH 5.4, 6.2 and 7.0. Only positive results are shown. The total protein concentration of each sample used in the assays is given in the table at the right. The diameter of activity corresponds to the difference between the diameter of the clear halo and the diameter of the well
