Question

You are studying an unknown microbe isolated from an acidic hotspring. Your experiments have revealed the following: 1) The cell wall is made up of proteins; 2) The membrane lipids contain ether linkages; 3) The organism is resistant to bacitracin and penicillin. Which of the following hypotheses are consistent with your findings? (Select all that are true.) select all that are True. The organism could be a member of the genus Mycobacterium. The organism could belong to the domain Archaes Ihe organism should be sensitive to (killed by) the peptidoglycan-targeting enzyme lysozyme. The organism does not belong to the domain Bacteria

Explanation / Answer

Domain archaea includes microorganisms capable of living in harsh conditions such as acidic environments, high temperatures and hot springs and in environments containing high salt concentrations. To live in such extrement condition archaea posess some special features in their cellular structures. These include cell wall contains heat and acid resistant proteins. The lipids of cellwalls contain ether linkages and these organisms resistant to antibiotics like bacitracin and penicillin. The option 2 and 4 are correct
