| 摘要 | Serratia marcescens TKU011, a protease- and chitosanase-producing bacterium, the optimized condition for protease and chitosanase production was found after the media were heated at 121 °C for 120 min and the culture was shaken at 25 °C for 5 days in 100 mL of medium containing 1% squid pen powder (SPP) (w/v), 0.1% K2HPO4, and 0.05% MgSO4. An extracellular metalloprotease with novel properties of solvent stable, and alkaline was purified from the culture supernatant of S. marcescens TKU011 with squid pen wastes as the sole carbon/nitrogen source. The enzyme was a monomeric protease with a molecular mass of 48–50 kDa by SDS–PAGE and gel filtration chromatography. The optimum pH, optimum temperature, pH stability, and thermal stability of TKU011 protease were 8, 50 °C, pH 5–11, and <40 °C, respectively. Besides protease and chitosanase, with this method, deproteinization of squid pen for β-chitin, the production of peptide and reducing sugar may be useful for biological applications. |
