A new method for direct detection of Listeria monocytogenes from foods by PCR.

abstract：:At certain stages in its growth cycle, Methanosarcina mazei produces an enzyme (disaggregatase) that causes aggregates to separate into single cells. M. mazei S-6 and LYC both produce this enzymatic activity, although the specificities of activities differ. The disaggregatase of M. mazei S-6 had little effect on strai...
