Information on the biopolymer poly-hydroxybutanoate (PHB)

a) Describe the process by which the biopolymer is produced naming any biologic and chemical agents used to produce it. Biopolymers argon naturally occurring polymers. corpus example is poly-hydroxybutanoate (PHB). PHB can be produced in a apprehension lab by feeding bacterium a aliment sufficient in nutrients until large colonies form and then withdrawing glucose. The bacteria directly start secreting PHB, which provides them with an energy store. In the 1980, the three genes in Alcaligenes eutrophus mandatory for the production of PHB were successfully cloned and transferred into a common bacteria, E.coli because it reproduced apace and has an good manipulated physiology. The PHB gene is transported into corn and maize plants, which allowed crops of PHB-producing plants to be large(p) and harvested. The mensuration of PHB that the organism can produce is from 30%-80% of its proclaim run dry weight. b) Identify and describe some of the chief(prenominal) uses of th e biopolymer and relate these uses to the properties of the biopolymer. The tractability of PHB allows for its use in fictile applications such(prenominal) as plastic bags and wrapping film while its force is useful in bottles and disposable nappies. Being easily perishable and renewable, it can similarly be used in storing medicative products so that is it decomposed at bottom the patients body.

Its main benefit of be biodegradable enables it to completely miss by natural environs in a before long amount of time. c) measure the use of the biopolymer in terms of its impact on the environs and whether or not it represents a separate alternativ! e to those plastics do from petrochemicals. Although PHB and polyethylene have similar properties, the chief(prenominal) exception of PHB is that it is biodegradable. Therefore, this allows better godforsaken management, and of being made from renewable crops rather than fossil fuels, which are gradually becoming...
