Expression and display of UreA of Helicobacter acinonychis on the surface of Bacillus subtilis spores

Microbial Cell Factories, 2010
Background The bacterial endospore (spore) has recently been proposed as a new surface display system. Antigens and enzymes have been successfully exposed on the surface layers of the Bacillus subtilis spore, but only in a few cases the efficiency of ...

A sporulation signature protease is required for assembly of the spore surface layers, germination and host colonization in Clostridioides difficile.

PLoS Pathogens, 2023
A genomic signature for endosporulation includes a gene coding for a protease, YabG, which in the model organism Bacillus subtilis is involved in assembly of the spore coat.

The PDZ domain of the SpoIVB serine peptidase facilitates multiple functions [PDF]

, 2001
During spore formation in Bacillus subtilis, the SpoIVB protein is a critical component of the sigma (K) regulatory checkpoint. SpoIVB has been shown to be a serine peptidase that is synthesized in the spore chamber and which self-cleaves, releasing ...

Characterization of Exosporium Layer Variability of Clostridioides difficile Spores in the Epidemically Relevant Strain R20291

Frontiers in Microbiology, 2020
Clostridioides difficile is a Gram-positive anaerobic intestinal pathogenic bacterium and the causative agent of antibiotic-associated diarrhea. C. difficile spore is a dormant state which acts as a vehicle of transmission and infection. In C.

Characterization of the Adherence of Clostridium difficile Spores: The Integrity of the Outermost Layer Affects Adherence Properties of Spores of the Epidemic Strain R20291 to Components of the Intestinal Mucosa [PDF]

, 2016
Indexación: Web of Science.Clostridium difficile is the causative agent of the most frequently reported nosocomial diarrhea worldwide. The high incidence of recurrent infection is the main clinical challenge of C. difficile infections (CBI). Formation of

Involvement of the spore coat in germination of Bacillus cereus T spores [PDF]

Applied and Environmental Microbiology, 1987
Bacillus cereus T spores were prepared on fortified nutrient agar, and the spore coat and outer membrane were extracted by 0.5% sodium dodecyl sulfate-100 mM dithiothreitol in 0.1 M sodium chloride (SDS-DTT) at pH 10.5 (coat-defective spores). Coat-defective spores in L-alanine plus adenosine germinated slowly and to a lesser extent than spores not ...

Coordinated Assembly of the Bacillus anthracis Coat and Exosporium during Bacterial Spore Outer Layer Formation

mBio, 2018
Bacterial spores produced by the Bacillales are composed of concentric shells, each of which contributes to spore function. Spores from all species possess a cortex and coat, but spores from many species possess additional outer layers.

Establishment of surface functionalization methods for spore-based biosensors and implementation into sensor technologies for aseptic food processing [PDF]

, 2020
Aseptic processing has become a popular technology to increase the shelf-life of packaged products and to provide non-contaminated goods to the consumers. In 2017, the global aseptic market was evaluated to be about 39.5 billion USD.

Manganese Oxidation by Spores and Spore Coats of a Marine Bacillus Species [PDF]

Applied and Environmental Microbiology, 1986
Bacillus sp. strain SG-1 is a marine bacterial species isolated from a near-shore manganese sediment sample. Its mature dormant spores promote the oxidation of Mn 2+ to MnO 2 .

Studies on the Bacterial Spore Coat

Nippon Saikingaku Zasshi, 1970
The chemical structures of three characteristic fractions each isolated from the dormant spore coats of Bacillus megaterium QM B1551 and B. megaterium ATCC 19213 were studied. The paracrystal fractions corresponding to the fibrillar structure of the inner coat composed mainly of keratin-like substance and alkali-soluble fractions consisted of acidic ...
