The heat generated by fermentor is 60 kcal/hr L. The cooling capacity of jacket is 10,000 kcal/hr m^2. For a cylindrical fermentor with H/D of 3, the jacket area (m^2) is porportional to fermentor volume (m^3) to the 2/3 power.
Area of Jacket (m^2) = 7*v^(2/3) (m^3)
What is the maximum volume of the fermentor that can be used without additional cooling capacity?© BrainMass Inc. brainmass.com October 16, 2018, 3:47 pm ad1c9bdddf
The heat generated by a fermentor with volume v [L] is
Using equalites relating heat generated and heat removed, the maximum volume of the fermentor that can be used without additional cooling is calculated. The calculation steps are shown.
Plant Biotechnology and Oak Domestication
You are a geneticist working for a firm that specializes in plant biotechnology. Explain what specific parts (fruit, seeds, stems, roots, etc.) of the following plants you would try to alter by genetic engineering, what changes you would try to make, and why, on a) corn, b) tomatoes, c) wheat, and d) avocados.
Only a few hundred of the hundreds of thousands of species in the plant kingdom have been domesticated for human use. One example is the almond. The domestic almond is nutritious and harmless, but its wild precursor can cause cyanide poisoning. The oak makes potentially nutritious seeds (acorns) that contain very bitter-tasting tannins. If we could breed the tannin out of acorns, they might become a delicacy. Why do you suppose we have failed to domesticate oaks?View Full Posting Details
