Summary
Purified cell walls were prepared fromAgrobacterium tumefaciens B 6 by extraction of intact cells with hot sodium dodecyl sulfate and digestion with proteases. Such preparations contained peptidoglycan that accounted for about 40% of their dry weight. Electron micrographs of the purified walls showed that they conserved their characteristic shape despite the drastic extraction procedure.
