In this work we present the bending elasticity modulus of archaeal lipid membrane in pure water environment. We added the details concerning the water purification (Lines 173–175). In other works the influence of different admixtures in the aqueous solution around the membrane was studied and the values depending on the type and the concentration of it for given lipid were reported. As the referee suggested we added such information with the corresponding references in the introduction section (Lines 57–60).
The observed fluctuations of the membrane do not destabilize it.
