Document Summary

You are put in charge of choosing an agitator to employ in your fermentation process. Searching ebay, you narrow down your option to two choices: You plan to operate your process 24 hours a day, 340 days out of the year, for 3 years. 1kw-hr is a unit of energy, the multiplication of power (in kwatts) and time (in hours). You want to sterilize 2 l of liquid medium before using it in a fermentation process. The initial concentration of cells in the medium is 100 cells/l. = 2 1 ( = 120 ) 5 (c) why might this be a desirable or advantageous outcome? (d) assume that 2 > 1. For your assumed value of 2, determine and show the corresponding value of 2 on the graph below. Question 4: bioreactors and media development (20 pts) In dr. maiorella"s bioreactor lecture, we considered the e ects of many parameters in design- ing bioreactors.
