Cell wall and lipid composition of Isosphaera pallida, a budding eubacterium from hot springs.


Isosphaera pallida is an unusual gliding, budding eubacterium recently isolated from North American hot springs. Electron micrographs of ultrathin sections revealed a cell wall atypical of eubacteria: two electrondense layers separated by an electron-transparent layer, with no evident peptidoglycan layer. Growth was not inhibited by penicillin. Cell walls… (More)
