Mgy377 lecture 11 bacterial cell cycle and growth. Bacterial growth: an increase in the number if cells, every cell has a lifespan. Species must replenish itself by growth: important to understand microbial growth. Fighting disease: during growth cycle, all cellular constituents increase in number, partitioning of replicated dna (chromosomes) depends on its association with membranes, time required for growth cycle varies greatly. E. coli replicates every 20 minutes in rich medium; e. coli replicates every 24 hours in. Binary fission the gut: cell divides into two cells. Elongate to approximately twice the length of the smallest cell. As a result of inward growth of cytoplasmic membrane and cell wall. Two daughter cells are pinched off: mechanism. Completion of septum with formation of distinct walls. Bacterial cell division: many proteins involved in cell division, fts = filamentous temperature sensitive. These proteins interact to form a division apparatus called the divisome.
