industrial uses of enzymes Flashcards
1
Q
what are immobilised enzymes
A
fixed on inert matrix
2
Q
example of immobilised enzymes
A
alginate beads
3
Q
5 advantages of immobilised enzymes
A
doesn’t contaminate
small quanity needed
enzymes can be added and removed
greater control over process
greater stability - denature at higher temps
4
Q
how does glass column work
A
substrate added at top diffuses into alginate matrix
forms enzyme sub comp
5
Q
why would you want to decrese flow rate
A
allow more contact time between enzyme and substrate - more complexes form
6
Q
why do alginate beads work past normal optimum temp
A
alginate gel fills and supports enzymes active site maintaining shape of the active site
7
Q
what do biosnesors do
A
able to select one type of mol from mixture even in very low concentrations
8
Q
A
