Webb1) Please label phases of bacterial growth for each curve (on the previous slide). Describe characteristics of bacterial growth during each phase. E.coli curve N.B at 30 C-The lag … In general, at low temperatures, microbes grow slower. At higher temperatures, microbes grow more quickly. For instance, pathogens often grow best at normal body temperature, but slowly at cooler temperatures outside the body or when body temperature increases during a fever.

A set of new molecular switches enable researchers to “push” bacteria to produce higher amounts of desired chemicals and proteins. The trick is to limit cell growth while maintaining the cells’ ability to produce chemicals. WebbEventually growth slows down, and the total bacterial cell number reaches a maximum and stabilizes. This is known as the stationary or post-exponential phase. At this stage it becomes important to know what method has been used to determine the growth curve. Webb24 feb. 2024 · Refrigeration.
