Molecular tiling on the surface of a bacterial spore - the exosporium of the Bacillus anthracis/cereus/thuringiensis group [PDF]

, 2017
Bacteria of the genera Bacillus and Clostridium form highly resistant spores, which in the case of some pathogens act as the infectious agents. An exosporium forms the outermost layer of some spores; it plays roles in protection, adhesion, dissemination,

Exosporium and Spore Coat Formation in Bacillus cereus T [PDF]

Journal of Bacteriology, 1973
The exosporium of Bacillus cereus T was first observed as a small lamella in the cytoplasm in proximity to the outer forespore membrane (OFSM) near the middle of the sporangium. Serial sections, various staining methods, and enzyme treatments failed to show any connections between the small lamella and the OFSM. The

Detection of YwdL in unwashed and fully washed exosporium using Western blotting.

, 2013
An anti-YwdL antibody was used to locate YwdL in unwashed and fully washed B. cereus ATCC 10876 and B. thuringiensis kurstaki 4d11 exosporium. Lanes 1 and 2 contain unwashed and washed ΔywdL exosporium, lane 3 and 4 unwashed and fully washed B.

Role of the exosporium in the stability of theBacillus sphaericusbinary toxin [PDF]

FEMS Microbiology Letters, 1994
The persistence of toxicity of the Bacillus sphaericus 1593 binary toxin was compared when produced in B. sphaericus, inside the exosporium, or in a recombinant B. thuringiensis strain, outside the exosporium. The stability of the toxin crystal was affected by temperature and quality of the water, but not by the location of the production in the ...

Silver stain PAGE of exosporium of ΔywdL compared to wild-type.

, 2013
Lane 1 corresponds to molecular weight protein standards. Lane 2 shows fully washed B. cereus wild-type exosporium and lane 3 shows fully washed ΔywdL exosporium. The same amount of total protein (15 µg) was applied to each lane for comparison.

A Single Amino Acid Substitution in CspA Increases Germination Sensitivity and Broadens Bile Salt Germinant Specificity in Clostridioides difficile Spores

Environmental Microbiology, Volume 28, Issue 6, June 2026.
In reservoir‐associated RT033 strains, we observe a natural rewiring of spore germination that lowers the activation threshold and broadens bile‐salt specificity, enabling germination at low germinant levels and in response to typically inhibitory bile‐salts common in animal hosts.

Exosporium Formation in Sporulating Cells ofClostridium botulinum78A [PDF]

Journal of Bacteriology, 1972
In sporulating cells ofClostridium botulinumtype A (NCA strain 78A), formation of exosporia was initiated laterally in the sporangia before the synthesis of the spore cortex. Mature spores were enveloped by multilayered exosporia; the layers were uniform in appearance, approximately 3 nm thick, with a center-to-center distance of 7 nm.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

The BclB Glycoprotein of Bacillus anthracis Is Involved in Exosporium Integrity [PDF]

Journal of Bacteriology, 2007
ABSTRACT Anthrax is a highly fatal disease caused by the gram-positive, endospore-forming, rod-shaped bacterium Bacillus anthracis . Spores, rather than vegetative bacterial cells, are the source of anthrax infections. Spores of B. anthracis are enclosed by a prominent loose-fitting
