Lecture 1 - Introduction

Question 1

What are 5 reasons for using a bioprocess?

Answer 1

Cells are better at certain types of chemistry

Conduct multi step syntheses with a very high selectivity

Synthesis complex organic chemicals

Premier synthesis machines for proteins

Very specific catalytic function

Question 2

What are 4 reasons why enzymes have not been used in the chemical industry

Answer 2

Inability to conduct a required step

Rates and yields often low compared with chemistry

Requirements for low product or substrate concentration

Instability at operating conditions

Question 3

In bioprocesses cells and enzymes maybe exposed to un natural conditions. What is the most logical design consideration for designing a bio reactor

Answer 3

The conditions have to be suited to that of the enzyme (bio-realistic)
