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

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 ...

Bacillus subtilis Intraspecies Interactions Shape Probiotic Activity Against Salmonella Typhimurium [PDF]
Microbial BiotechnologyABSTRACT Commercial 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 ...

Colony shape as a genetic trait in the pattern-forming Bacillus mycoides [PDF]
BMC Microbiology, 2002 Bacillus mycoides Flügge, a Gram-positive, non-motile soil bacterium assigned to Bacillus cereus group, grows on agar as chains of cells linked end to end, forming radial filaments curving clock- or counter-clockwise (SIN or DX morphotypes). The molecular mechanism causing asymmetric curving is not known: our working hypothesis considers regulation of ...

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

Identification of Bacillus subtilis genes for septum placement and shape determination [PDF]
Journal of Bacteriology, 1992 The Bacillus subtilis divIVB1 mutation causes aberrant positioning of the septum during cell division, resulting in the formation of small, anucleate cells known as minicells. We report the cloning of the wild-type allele of divIVB1 and show that the mutation lies within a stretch of DNA containing two open reading frames whose predicted products are ...

Shaping an Endospore: Architectural Transformations During Bacillus subtilis Sporulation [PDF]
Annual Review of Microbiology, 2020 Endospore formation in Bacillus subtilis provides an ideal model system for studying development in bacteria. Sporulation studies have contributed a wealth of information about the mechanisms of cell-specific gene expression, chromosome dynamics, protein localization, and membrane remodeling, while helping to dispel the early view that bacteria lack ...

Cheaters shape the evolution of phenotypic heterogeneity in Bacillus subtilis biofilms [PDF]
The ISME Journal, 2018 ABSTRACTBiofilms are closely packed cells held and shielded by extracellular matrix composed of structural proteins and exopolysaccharides (EPS). As matrix components are costly to produce and shared within the population, EPS-deficient cells can act as cheaters by gaining benefits from the cooperative nature of EPS producers.

Autolysins and shape change in rodA mutants of Bacillus subtilis [PDF]
Journal of Bacteriology, 1978 The biochemical phenotype of rodA mutants was not affected by the simultaneous presence in double mutants of the lyt gene which makes them 90 to 95% deficient in autolysin action. The only morphological effect of this deficiency on the expression of the rod gene was that both the rod and the coccal forms of the mutant failed to separate and grew as ...
