microorganism: degrades plastic
ideonella sakaiensis
apparatus in which practical biochemical reactions are performed, often with use of enzymes and/or living cells
bioreactors
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
fermentation
proportionally produced with the growth of the microorganism, since these are directly involved in cellular metabolism
growth-associated products
produced at the stationary phase of the microorganism
non-growth-associated products
example of non-growth-associated products
antibiotics
hybrid of growth and non-growth-associated products
mixed-growth-associated products
describe the production or consumption of a material per unit consumption of another material
yield coefficients
