Bacteria Replication

Most prokaryotes reproduce by a process of binary fission, in which the cell grows in volume until it divides in half to yield two identical child cells. The generation time, varies among bacteria and is controlled by many environmental conditions. For example, Clostridium perfringens, one of the fastest-growing bacteria, has an optimum generation time of about 10 minutes; #escherichiacoli - #ecoli can double every 20 minutes; and the slow-growing #Mycobacterium #tuberculosis has a generation time in the range of 12 to 16 hours.
But how this process look like on that micro level? Here is Helix Animation take
