This lab bench displays the different means of growing bacterial cultures. On the left are two
large flasks containing LB growth media. In the foreground, the culture is in the early stages of
exponential growth while the flask in the background is much older, with the cells inside forming
endospores. On the right, an LB-agar plate streaked with bacteria is displayed, in front of two
stacks of additional uninoculated plates; on the left are LB-agar plates (yellow), and on the right,
MacConkey agar plates (pink). The cells in the flask near the back of the benth are forming
endospores. Explain what conditions they are experiencing that would cause this to occur. If you
were trying to induce the formation of spores in the flask, what other conditions might cause
this?.
