Archae appeared early in the course of biological evolution and those in existence today represent relics of ancient forms of life. A few other extremophiles, mainly the types that can survive in hot springs, have already been sequenced. But this is the first salt-loving micro-organism for which the genome has been cracked.''

I grew halobacterium halobium in shaker flasks at 37 deg celsius using oesterhelt's recipe for media.
The cells on being ahrvested did not have any bacteriorhodopsin.The reason told to me was the cells might have developed an alternate pathway for transporting protons.
Can anyone help me?
