Biopolymers

Question 1

Definition

Answer 1

A special group of macromolecules produced by living organisms.

Question 2

Need for biopolymers

Answer 2

To reduce dependence on synthetic polymers which are not biodegradable and are manufactured from crude oil, which is a non-renewable resource.

Question 3

Biopol

• structure
• brief description of production

Answer 3

It’s a PHA and it’s a co-polymer consisting of the monomers PHB and PHV.

Using the fermentation of sugars by bacterium, and then seperate and purified.

Question 4

Biopol

• current research to reduce costs
• properties - compared to current polymer

Answer 4

Genetic engineering: inserting genes from R•eutrophus directly into plants/bacteria such as E•coli to make and store the biopolymer as granules in their cell wall. Result in faster growth, better yields, easier recovery.

B is denser, UV resistant, 100% biodegradable, stable in air and humid conditions, recyclable, burns cleanly, biocompatible and made from renewable resources.

Question 5

Biopol

• advantages
• disadvantages

Answer 5

Advantages

• reduce negative effects on the environment
• more sustainable

Disadvantages - too expensive
