A bacterial strain has a generation time of 30 min, how long would it take an exponentially growing culture to increase from a titre of 5 x 103 cells per ml to 4 x 109 cells per ml? How many generations would have elapsed? Show all of your calculations. G = t/n to calculate generation time (i.e. for population to double) During the growth of the culture, periodic observations of the cells under the microscope have revealed the occurrence of typical rod-shaped cells. However, after further incubation, they appeared to change their morphology to form small oval or spherical-shaped structures. What do these structures likely represent? And what are the likely factors contributing to this observation? Explain what growth phase this culture will be in.
