Production and Partial Purification of Tannase from Serratia Marcescens Isolated from Different Sources

Purification and partial characterization of a bacteriocin from Serratia marcescens.

Bacteriocin JF246 has been purified from mitomycin C-induced Serratia marcescens cells by salt extraction, ammonium sulfate fractionation, and chromatography on QAE-Sephadex and SP-Sephadex. The purified material is homogeneous on polyacrylamide gel electrophoresis in the presence of 2% sodium dodecyl sulfate or 6 m urea. In the absence of these agents, the bacteriocin associates into aggregate...

Purification and partial characterization of psychrotrophic Serratia marcescens lipase.

Serratia marcescens isolated from raw milk was found to produce extracellular lipase. The growth of this organism could contribute to flavor defects in milk and dairy products. Serratia marcescens was streaked onto spirit blue agar medium, and lipolytic activity was detected after 6 h at 30 degrees C and after 12 h at 6 degrees C. The extracellular crude lipase was collected after inoculation o...

Purification and properties of L-asparaginase from Serratia marcescens.

The purification and properties of a tumor inhibitory l-asparaginase from Serratia marcescens are described. The following properties of the enzyme were examined: kinetics of the enzyme reaction, catalytic activity as a function of pH, boundary sedimentation velocity, electrophoresis on polyacrylamide gel, immuno-electrophoresis against homologous and heterologous antisera, immunodiffusion, blo...

Chitinases from Serratia marcescens

Serratia marcescens is one of the most effective bacteria for degradation of chitin, a 1,4-β-linked polymer of N-acetyl-β-Dglucosamine (GlcNAc). Chitinolysis by S. marcescens involves at least four enzymes and a chitin-binding protein. Studies of the enzymology and the structures of the enzymes provide insight in how a natural set of chitinolytic enzymes may be built up. S. marcescens chitinase...
