Information on the biopolymer poly-hydroxybutanoate (PHB)

a) Describe the process by which the biopolymer is produced naming any biological and chemical agents used to produce it. Biopolymers argon naturally occurring polymers. unity example is poly-hydroxybutanoate (PHB). PHB can be produced in a scientific discipline lab by feeding bacteria a dieting 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 readily 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 heavy(p) and harvested. The mensuration of PHB that the organism can produce is from 30%-80% of its give run dry weight. b) Identify and describe some of the of import uses of the bi opolymer and relate these uses to the properties of the biopolymer. The tractability of PHB allows for its use in fictile applications much(prenominal) as plastic bags and wrapping film while its military capability is useful in bottles and disposable nappies. Being easily biodegradable and renewable, it can similarly be used in storing medicinal products so that is it decomposed at bottom the patients body.

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