Day 4 - Thursday - 1/11/2007
Hi bloggy, today was experiment 4 and what a slack day for us. We didn’t do anything. Our lab tech helped us do the final step which is to harvest the protein. He also showed us a history chart of all the parameters that were used in the fermenter.

Aren’t computers just dandy? They do the hard work for us. By setting the limits, the computer will control the optimal range of values for the cells to growth. For example, the green line represents the stirring speed. This line fluctuates soooo much as it tries to bring the amount of dissolved oxygen to optimal levels. The blue line also fluctuates together with the green line. All the parameters are kept at a certain range. Never does it goes beyond the range. Cheers to computers. Imagine what would happen if these things were not computerized? We’ll be camping in the lab measuring the pH/temperature/PO
2 of the fermenter and try to stabilize the parameters to an optimal range EVERY waking moment. How convenient computers have made our lives!
Well I better sign off here. Next Monday will be a long one. 3 hours of fun. Can’t wait for it! Peace out bloggy!
