Transformation of undomesticated strains of Bacillus subtilis by protoplast electroporation.
A rapid method combining the use of protoplasts and electroporation was developed to transform recalcitrant wild strains of Bacillus subtilis. The method described here allows transformation with both replicative and integrative plasmids, as well as with chromosomal DNA, and provides a valuable tool for molecular genetic analysis of interesting Bacillus strains, which are hard to transform by c...
متن کاملGenetic analysis of Bacillus stearothermophilus by protoplast fusion.
Efficient and reliable protoplasting, regeneration, and fusion techniques were established for the prototrophic strain Bacillus stearothermophilus NUB36. Auxotrophic mutants were isolated, and protoplast fusion was used to construct isogenic mutant strains and for chromosomal mapping. Markers were mapped using two-, three-, and four-factor crosses. The order of the markers was hom-1-thr-1-his-1...
متن کاملElectron microscopic study of Bacillus subtilis protoplast fusion.
When protoplasts derived from sporulating cells of Bacillus subtilis were fused by exposure to polyethylene glycol (PEG) and fixed immediately thereafter, protoplasts with two enclosed prespores could be seen by electron microscope. The number of fusion events was greatly increased, and multiply fused protoplasts appeared, when the PEG-treated suspension was diluted in hypertonic broth and rein...

Techniques and media for the production and regeneration of stable Clostridium acetobutylicum protoplasts are described.
متن کاملProtoplast Formation and Regeneration in Acetobacter Pasteurianus
Method for production and regeneration of Acetobacter pasterianus protoplasts is described. The protoplasts were obtained by treatment of cells with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplast formation was obtained in protoplast buffer with NaCl (0.5M) as ...
