[[Image:Note mini.png]]''<font color = red> TEACHERS: ''Note that the original strain is supposed to smell like bananas only during stationary phase but we have found that it actually smells throughout the measurements we've made...perhaps because stationary phase activity starts earlier than we think. Similarly, we have seen the strain 1-2, which has the stationary phase promoter and the inverter, is more active throughout the growth curve and generates a stronger banana smell than strain 1-3, which has the log phase promoter.</font color><br> | [[Image:Note mini.png]]''<font color = red> TEACHERS: ''Note that the original strain is supposed to smell like bananas only during stationary phase but we have found that it actually smells throughout the measurements we've made...perhaps because stationary phase activity starts earlier than we think.
