bioreactors which use living cells
fermenters
elimination, removal, or deactivation of all life forms
sterilization
most common used method, which involves an autoclave or pressure chamber
steam sterilization
operating parameters of steam sterilization
15 mins holding stage at 15 psi and 121 deg C
design criterion for sterilization; reflects combined effects of sterilization time, temperature, and cell characteristics
Del Factor
use of microorganisms to convert sugars to organic acids, gases, or alcohol in anaerobic conditions
