TL;DR: Examination of lipid composition of seven phylogenetically divergent strains of subdivision 4 of the Acidobacteria, a bacterial group that is commonly encountered in soil, found the presence of ether bonds in the membrane lipids does not seem to be an adaptation to temperature, because the five mesophilic isolates contained a larger amount of ether lipids than the thermophile “Ca. Chloracidobacterium thermophilum.”

TL;DR: The position of methylation of iso-diabolic acid may be controlled by the phylogenetic affiliation within the Acidobacteria and thus may not be a direct but an indirect response environmental to environmental conditions as inferred from the bacterial GDGT distributions in soil, peat and rivers.

TL;DR: The presence of six sterols in the psychrophilic methanotrophic bacterium, Methylosphaera hansonii, suggests that the capacity for sterol biosynthesis in methanOTrophic bacteria is limited to the family Methylococcaceae but which have widely different optimal growth temperatures.

TL;DR: Intact ladderane phospholipids made up a high percentage of the lipid content in the cells of “Candidatus Kuenenia stuttgartiensis”, suggesting that ladderane lipids are also present in membranes other than the anammoxosome, and indicates that hopanoids are anaerobically synthesised byAnammox bacteria.

TL;DR: Compared with currently described members of the genus Planctomyces, the isolates from northern wetlands do not form long and distinctive stalks, have greater tolerance of acidic conditions and low temperatures, are more sensitive to NaCl, lack pigmentation and degrade a wider range of biopolymers.
