Some strains of Halobacterium have a novel mechanism for generating ATP. Beneath the phototrophic layer are sulphur-oxidising bacteria, such as Beggiatoa alba and Thiobacillus halophilus. Vertebrate retinas contain rhodopsin as a visual photosyynthesis pigment.
Archaebacteria are often though not exclusively found in harsh environments - fo are extremophiles. Purple membrane may account for half of the total cell membrane surface area. This helps explain the genetic plasticity that has been observed in Halobacterium. Content on this website is from high-quality, licensed material originally published in print form. Halobacterium species are rod-shaped and enveloped by a single lipid bilayer membrane surrounded by phogosynthesis S-layer made from the cell-surface glycoprotein.
