Molecular sieving by the Bacillus megaterium cell wall and protoplast.
Passive permeabilities of the cell wall and protoplast of Bacillus megaterium strain KM were characterized by use of 50 hydrophilic probing molecules (tritiated water, sugars, dextrans, glycols, and polyglycols) which varied widely in size. Weight per cent uptake values (R(w)) were measured at diffusional equilibrium under conditions that negated the influences of adsorption or active transport...
متن کاملCell wall residues in yeast protoplast preparations.
Protoplast preparations made from Saccharomyces cerevisiae by prolonged treatment with snail digestive juice contained fibrils and chitinous bud-scar residues from the original cell wall.
متن کاملReconstitution of cell wall synthesis in toluene- and LiCl-treated Bacillus megaterium cells by addition of a soluble protein extract.
Proteins required for the synthesis of peptidoglycan and incorporation of diaminopimelic acid into cell walls have been solubilized from Bacillus megaterium toluene-treated cells. Some of these proteins might have been removed from the cytoplasmic membrane through the cell wall by extraction with LiCl. The solubilized proteins have molecular weights in the range of 40,000 to 70,000 and can be a...
متن کاملProtoplast formation and cell wall regeneration in Clostridium perfringens.
A protocol was developed for the efficient production and regeneration of Clostridium perfringens protoplasts. Cell wall regeneration frequencies of up to 5% were obtained.

Weibull, Claes (Central Bacteriological Laboratory of Stockholm City, Stockholm, Sweden). Plasmolysis in Bacillus megaterium. J. Bacteriol. 89:1151-1154. 1965.-Sucrose solutions stronger than 1 m caused plasmolysis in Bacillus megaterium strain M, whereas concentrated NaCl and KNO(3) solutions were ineffective. In plasmolyzed cells, mesosome bodies were found in pockets between the cytoplasmic ...
