Abstract
The purpose in this experiment of growth dynamics of E. coli in varying media
was to determine which media produces the maximum number of cells per unit time.
First a control was established for E. coli in a 1.0x nutrient br.... Part 2 of Paper
..../mL
and finally pH 6.0 producing 579,557cells/mL. The remaining four media, after
calculations, produced cell counts greater than the control: 2X with 1,087,009
cells/mL; 0.5X with 2,205,026 cells/mL; pH 8 with 3,583,750 cells/mL and finally
pH 7.0 with 8,090,325 cells/mL. From these results the conclusion can be made
that the environment is a controlling factor in the growth dynamics of E. coli.
This was found through the regulation of pH and nutrient concentrations. In the
presence of the.... |
