Cell separation system studied by mixed culture of single wild strain with tetrads-forming mutant strain of Micrococcus luteus.
Mixed culture study of singly occurring wild strain IFO 3333 of Micrococcus luteus and a tetrads-forming mutant strain MT, in the absence or presence of trypsin, supported our previous assumption that at least two kinds of separation systems were involved in cell separation of M. luteus, the one having a physiological role in cutting off the outermost layer of the cell wall (separation system-Om) and the other in cutting off the inner layer of the "proper" cell wall or the septum (separation system-In). The separation system-Om of IFO 3333 insensitive to trypsin substituted, freely from the cells, for that of MT sensitive to trypsin.
