Summary X-ray photoelectron spectroscopy (XPS) was used to analyze the outermost (2–5 nm) surface of bacterial cells. Elemental analysis of the cell surfaces in Bacillus subtilis 168 and Bacillus megaterium KM gave a strong P signal attributed to t

The limiting sizes of molecules that can permeate the intact cell wall and protoplast membrane of Saccharomyces cerevisiae were determined from the inflection points in a triphasic pattern of passive equilibrium uptake values obtained with a series o

The thin-sectioned spore of Bacillus thuringiensis resembles that of Bacillus cereus in fine structure. Planar inclusions occur between the exosporium and spore coat and are structured differently from the parasporal crystal outside the exosporium. I

Single whole spores of bacillus cereus T were analyzed by scanning electron microscopy and electron microprobe X-ray microanalysis before and after high-temperature (600 °C) ashing in air. High-temperature ashing consisted of a centripetal oxidation
