A dynamic, ring-forming MucB / RseB-like protein influences spore shape in Bacillus subtilis [PDF]

PLOS Genetics, 2020
How organisms develop into specific shapes is a central question in biology. The maintenance of bacterial shape is connected to the assembly and remodelling of the cell envelope. In endospore-forming bacteria, the pre-spore compartment (the forespore) undergoes morphological changes that result in a spore of defined shape, with a complex, multi-layered

Nutrient Availability and Biofilm Polysaccharide Shape the Bacillaene-Dependent Antagonism of Bacillus subtilis against Salmonella Typhimurium

Microbiology Spectrum, 2022
Probiotic bacteria represent an alternative for controlling foodborne disease caused by Salmonella enterica , which constitutes a serious concern during food production due to its antibiotic resistance and resilience to environmental stress.

Overproduction of Flotillin Influences Cell Differentiation and Shape in Bacillus subtilis [PDF]

mBio, 2013
ABSTRACT Bacteria organize many membrane-related signaling processes in functional microdomains that are structurally and functionally similar to the lipid rafts of eukaryotic cells. An important structural component of these microdomains is the protein flotillin, which seems to act as a chaperone in recruiting other proteins to ...

Direct observation of a crescent-shape chromosome in expanded Bacillus subtilis cells [PDF]

Nature Communications
AbstractBacterial chromosomes are folded into tightly regulated three-dimensional structures to ensure proper transcription, replication, and segregation of the genetic information. Direct visualization of chromosomal shape within bacterial cells is hampered by cell-wall confinement and the optical diffraction limit.

Fruit Morphology, Antioxidant Activity, Total Phenolic and Flavonoid Contents of Salacca zalacca (Gaertner) Voss by Applications of Goat Manures and Bacillus velezensis B-27

Caraka Tani: Journal of Sustainable Agriculture, 2021
Snake fruit (Salacca zalacca (Gaertner) Voss) is one of indigenous fruits from Southeast Asia that has been consumed for its antioxidant contents. Improving the fruit quality might increase its benefits for human health.

Two Putative Polysaccharide Deacetylases Are Required for Osmotic Stability and Cell Shape Maintenance in Bacillus anthracis [PDF]

Journal of Biological Chemistry, 2015
Membrane-anchored lipoproteins have a broad range of functions and play key roles in several cellular processes in Gram-positive bacteria. BA0330 and BA0331 are the only lipoproteins among the 11 known or putative polysaccharide deacetylases of Bacillus anthracis. We found that both lipoproteins exhibit unique characteristics.

Control of Cell Shape in Bacteria [PDF]

Cell, 2001
In the absence of an overt cytoskeleton, the external cell wall of bacteria has traditionally been assumed to be the primary determinant of cell shape. In the Gram-positive bacterium Bacillus subtilis, two related genes, mreB and mbl, were shown to be required for different aspects of cell morphogenesis.

Cell morphology maintenance in Bacillus subtilis through balanced peptidoglycan synthesis and hydrolysis

Scientific Reports, 2020
The peptidoglycan layer is responsible for maintaining bacterial cell shape and permitting cell division. Cell wall growth is facilitated by peptidoglycan synthases and hydrolases and is potentially modulated by components of the central carbon ...

Bacillus subtilis Intraspecies Interactions Shape Probiotic Activity Against Salmonella Typhimurium

Microbial Biotechnology
ABSTRACTCommercial probiotics are often formulated as multi‐strain cocktails, but the effects of social interactions, particularly between strains of a species, are often neglected, despite their potential to contribute to higher‐order interactions where these interactions could affect those with a third party.

A Novel Spore Protein, ExsM, Regulates Formation of the Exosporium in Bacillus cereus and Bacillus anthracis and Affects Spore Size and Shape [PDF]

Journal of Bacteriology, 2010
ABSTRACT Bacillus cereus spores are assembled with a series of concentric layers that protect them from a wide range of environmental stresses. The outermost layer, or exosporium, is a bag-like structure that interacts with the environment and is composed of more than 20 proteins and glycoproteins. Here, we identified
