Studies of L Forms and Protoplasts of Group a Streptococci
Intact bacterial membranes have been isolated from protoplasts prepared from Group A streptococci by a cell wall-dissolving enzyme. A membrane fraction with identical chemical and serological properties has been obtained by differential centrifugation of mechanically disrupted streptococci. The membrane is chemically distinct from the cell wall and is composed of 72 per cent protein, 26 per cen...
متن کاملGrowth of bacterial L forms and bacterial protoplasts.
Numerous morphological, physiological, and biochemical studies have been carried out on bacterial forms exhibiting a pronounced osmotic fragility (for review see Weibull, 1958b). Naked bacterial protoplasts, obtained by means of a complete removal of the cell wall by lysozyme in a sucrose medium (Weibull, 1953) offer an example of such an osmotically fragile structure. Osmotically sensitive for...
متن کاملReversion of Bacillus megaterium protoplasts to the bacillary form.
Photomicrographic evidence of reversion of Bacillus megaterium protoplasts to the bacillary form on soft agar plates hypertonic medium is demonstrated.
متن کاملApplications of quadratic D-forms to generalized quadratic forms
In this paper, we study generalized quadratic forms over a division algebra with involution of the first kind in characteristic two. For this, we associate to every generalized quadratic from a quadratic form on its underlying vector space. It is shown that this form determines the isotropy behavior and the isometry class of generalized quadratic forms.
متن کاملInhibitory protein controls the reversion of protoplasts and L forms of Bacillus subtilis to the walled state.
When the cell wall of Bacillus subtilis is removed by lysozyme and the resultant protoplasts are plated on hypertonic soft agar medium, each protoplast forms an L colony. L bodies from such L colonies again plate as L-colony-forming units (CFU). However, if protoplasts or L bodies are "conditioned" by 1 h of incubation in 0.4% casein hydrolysate medium and then incubated in 25% gelatin medium f...
