Question

You are studying an autoinduction system in Peytonius mannii and you discover that it only forms a biofilm when it is in high cell density and Marvinius harrisoni is also present in high cell density.

a. how mnay autoinduction molecules do you expect to find in this system and which organisms produce it?

b. you find that the autoinducer regulates biofilm formation at the transcriptional level. Which one of the following types of autinducer molecules is likely to be involved. Why? Homoserine lactones, polypeptides, polysaccharides, polynucleotides.

c. after the formation of tis co-species biofilm you wash out the chlorobiphenyl medium and give it glucose as a food source. When you do so, yo see that the two species physically separate from each other. Explain why they do this.

Answer 1

The Cell Is made up in the lipoportin and glucose .This are amino sugar .the boifilm formation are involved in abtiducer molecules they are the made up and help in the biofilm formation and high density level increase like the amino sugar polypeptide , polysaccharide , polynucleotide .
