Answer #1

Answer:- Test for checking disruption of cell wall using material like beta lactam family antibiotics (Penicillin) can be performed for confirmation of identity for isolated unicellular organism. Penicillin like antibiotics which belongs to beta lactam familiy of antibiotics can disrupt cell wall made up of peptidoglycan present in bacterial cell but not in algal cell because cell wall made up of other polysachharides not peptidoglycan.

Case I- If the isolated single celled organism showing positive result for cell wall lysis test, then it confirms its identity as bacterial cell.

Case II- If test show no cell wall disruption by using penicillin or similar antibiotics, then ofcourse it is an algal cell.

You have isolated a bacterium in pure culture. Based on some morphological and biochemical tests you suspect this bacterium is of the species Klebsiella pneumoniae. In order to confirm this you utilize molecular techniques to assess the relatedness of your isolate to a type strain (a well-characterized version) of K. pneumoniae. What two molecular methods would you use to compare your isolated bacterium to K. pneumoniae? What criterion would you use with these two tests to confidently say your isolated...

Are bacterial walls simpler or more complex? If you remove the cell wall of a bacterium, the cell must be kept in isotonic solution (same concentration of solutes as the cytoplasm). Why is that? What does this tell you about the main function of the cell wall in bacteria? What are the other functions? How is the outer membrane of gram-negative bacteria similar to the plasma membrane and how different? Define/describe the relevance of lipopolysaccharide and porins What is the...
