Cell packets of Micrococcus lysodeikticus (luteus) mutant strain MT grown in medium supplemented with trypsin consisted of a tetrad as the unit structure. An interstice was observed between the unit‐tetrads, and a three dimensional structure of cell packets was maintained by the cell wall‐bridge along the rim of the cell packets which linked each unit‐tetrad. This unique structure of strain MT cell packets seemed to occur when the cell separation was suppressed locally, i.e., when the cross wall inside the initial site of cell separation was cut off, while the wall outside the initial site of separation was not cut off but remained as a joint of the daughter cells. The mechanism of cell wall‐bridge formation is discussed in connection with cell separation.
