Document Summary
Caulobacter crescents will undergo division into swarmer cells (motlile) and stalked cells (that remain adhesive) > this allows cells to explore and increase the ability to survive. Spore can revive and become resistant to many stresses so they pose a problem (why we autoclave) but also allow the species to survive. Spores: ** remember that sporulation is risky for cells to avoid starvation so you need a lot of regulation check points (phosphorelay) Metabolically inert - held in suspended animation". Spore coating: surrounded by a coat of mostly proteins (outer shell) and some lipids unlike the cell membrane, the cortex contains peptidoglycan > all made by the mother cell and controlled by sigma k. As soon as the spore binds a geminant it will come back to life (has all the necessary. Di erentiation if cell types in bacillus subtitis: Can form distinct cells types including: (di erentiate these types by di erential.
