Sporulation of protoplasts

Folia Microbiologica, 1964
Vegetative cells ofBacillus megaterium formed protoplasts in a sucrose-stabilized medium under the influence of lysozyme. The protoplasts sporulated during subsequent incubation. The morphological properties, germination, resistance to u. v. irradiation and thermo-resistance of protoplast spores were the same as with normal cells.

Sporulation of Bacillus subtilis

Current Opinion in Microbiology, 2004
Differentiation of vegetative Bacillus subtilis into heat resistant spores is initiated by the activation of the key transcription regulator Spo0A through the phosphorelay. Subsequent events depend on the cell compartment-specific action of a series of RNA polymerase sigma factors.

Cannibalism by Sporulating Bacteria

Science, 2003
Spore formation by the bacterium Bacillus subtilis is an elaborate developmental process that is triggered by nutrient limitation. Here we report that cells that have entered the pathway to sporulate produce and export a killing factor and a signaling protein that act cooperatively to block ...

Clostridioides difficile Sporulation

Some members of the Firmicutes phylum, including many members of the human gut microbiota, are able to differentiate a dormant and highly resistant cell type, the endospore (hereinafter spore for simplicity). Spore-formers can colonize virtually any habitat and, because of their resistance to a wide variety of physical and chemical insults, spores can ...

Proteolysis in Bacterial Sporulation

1980
Publisher Summary Endospore formation and germination in various Bacillus species provide attractive experimental models for the study of cellular differentiation. These bacteria offer the advantages of easy cultivation and physiological manipulation, the possibility of genetic analysis, and a well-defined, relatively simple unicellular ...

Sporulation of Mesophilic Clostridia

Journal of Applied Bacteriology, 1967
SUMMARY The commoner mesophilic clostridia have been screened for sporulation in several meat and other media. A method employing enriched spent medium has also been evaluated. A cooked meat medium based on Hartley's digest broth supported sporulation of more species than any other medium examined.
