optimization of cell disruption with bead mill

  • An Optimized Protocol for Bacterial Cell Disruption with

    The efficiency of the disruption process for the release of tyrosine phenol lyase from Citrobacter freundii in a bead beater with zirconium beads was studied. Under optimum conditions of cell disruption (0.1mm zirconium beads 6mg/mL dcw cells 1mM EDTA 0.7mM DTT and 9 disruption cycle) the specific activity of enzyme reached to 0.038 IU/mg.
