antibacterial activity of nisin. antibacterial activity of nisin. Write one paragraph as an analysis of the article once finished then Answer the following questions separately in different paragraphs. Cite the paper uploaded.

1.Fig 5 shows that in vitro release profiles in phosphate buffer of pure nisin or nisin from from nanocapsules are very similar.Based on this figure the encapsulation did’t bring an advantage i.e. better control the release of nisin.
In this case why the authors encapsulated nisin ?

2.There are some interactions between nisin and the two polymers ?If yes, with which polymer and what type of interactions ?
3.Explain the role of surfactant on the encapsulation of nisin ? What are other syrfactants which can play the same role ?

4.Is chitosan soluble in water ? Please discuss the water solubilities of all reagents used in nanocapsules preparation.

5.Based on TEM micrographs in fig. 4 showing the encapsulated nicin.
Please give particles size and parameters which can influence it as well as encapsulation efficacy.
6.  describe how the antibacterial activity of nisin was evaluated and the findings illustrated in fig 6 ?
