Abstract
Proteolytic enzymes perform hydrolysis of the peptide bonds in the protein and most commonly use in the industry. Pseudoxanthomonas sp. WD12 and WD32 were previously isolated as protease producers from a rotten wood sample. Here, we report the secreted proteolytic enzymes. The optimum enzyme reaction temperature for the secreted crude enzyme from the strain WD12 and WD32 were $50^{\circ}C$ at pH 9.0 and $45^{\circ}C$ at pH 8.0, respectively. The enzyme activities of both strains were increased by addition of KCl, NaCl, $CaCl_2$ or $MnSO_4$, and decreased by addition of $AgNO_3$, $CuSO_4$, $FeCl_3$ or $AlCl_3$. Secreted enzymes of both strains were most strongly inhibited by addition of $FeCl_3$ or $CuSO_4$. Taken together these results, WD12 could be a candidate strain of industrial alkaline protease production.
