What would be some reasons as to why a bacterial growth curve would produce unexpected results? For example, an E. coli culture increases after the stationary phase? Or why there is no statioViable Cell Concentration vs. Time of Escherichia coli E 1.00E+08 1.00E-07 C 1.00E+06 60 80 100 120 140 0 20 40 Time (minutes) Spectrophotometer -96 Well Platenary phase? I am trying to interpret results that I have from a lab experiment.

Answer #1

In Escherichia coli, some cells called persisters remain dormant during the log phase of growth and start to grow during or after the stationary phase. This could be the reason for getting unexpected results like not getting the stationary phase or increase in cell density after stationary phase.

    this is a bacterial growth curve experiment . please explain rhe results Procedure: You will follow the growth of E. coli over the course of the period (3 hrs) by making direct counts of the bacterial suspension by measuring the turbidity of a sample at a given time with a spectrophotometer. The data obtained from the direct counts will be used to plot a partial growth curve. Summary: Turbidity Counts with the Spectrophotometer to measure absorbance at 600. Direct Counts...

    please use these results of a growth curve experiment to answer the following questions Questions 1) Plot the OD600 readings and cell concentration for each time point on a scatterplot with a line connecting the points. Have the measured data (OD600 and cell concentration) on the y-axis against the time on the x-axis using Excel (or other computer based data/graphing program). It is helpful to set the y-axis on a log scale for the cell concentration measurements. 2) Can you...

    Metabolic Pathway Engineering Problem Set 5 Engineering a Fermentation System: Fermentation of plant matter to produce ethanol for fuel is one potential method for reducing the use of fossil fuels and thus the CO2 emissions that lead to global warming. Many microorganisms can break down cellulose then ferment the glucose to ethanol. However, many potential cellulose sources, including agricultural residues and switchgrass, also contain substantial amounts of arabinose, which is not as easily fermented. Escherichia coli is capable of fermenting...
