In exponentially growing and dividing cells of Streptococcus faecalis, it is proposed that the leading edge of the annularly closing cross wall is the point of extension for both cross wall and peripheral wall. Peripheral wall extension is thought to be produced by the separation or splitting of the cross wall at its junction with peripheral wall. This results in the pushing of the equatorial wall bands, found on S. faecalis walls, to subsequatorial positions. These bands therefore mark the separation of old wall from new wall. Mesosomal formation was observed usually to precede cross wall initiation.
在粪链球菌指数生长和分裂的细胞中，有人提出环形闭合横壁的前沿是横壁和外周壁延伸的位点。外周壁的延伸被认为是由横壁在其与外周壁交界处的分离或分裂产生的。这导致在粪链球菌细胞壁上发现的赤道壁带被推到次赤道位置。因此，这些带标志着旧壁与新壁的分离。通常观察到中介体的形成先于横壁的起始。
