Question

g) Suppose that this researcher made the necessary improvements to her experiment, yet
the bacterial colony remained its original size. Does this mean that her experiment is a
failure? Explain your answer.

Answer 1

Answer:

The continued increase in colony numbers with extended incubation times over the 12-week incubation period was also observed with all of the media shown in Fig. ​ 3 that were based on medium VL55 with gellan as the solidifying agent but with different growth substrates (data not shown).

Explanation:

Answer 2

Answer:

Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than in the size of individual cells. The growth of a bacterial population occurs in a geometric or exponential manner: with each division cycle (generation), one cell gives rise to 2 cells, then 4 cells, then 8 cells, then 16, then 32, and so forth. The time required for the formation of a generation, the generation time (G), can be calculated from the following formula:
