The triterpenoid curcumene mediates the relative hydrophilicity of Bacillus subtilis spores

mBio
Spores of Bacillus subtilis are surrounded and protected by the coat and the crust, multi-layered structures mainly made of proteins and polysaccharides.

Evidence that a chaperone–usher-like pathway of Myxococcus xanthus functions in spore coat formation

, 2011
Many bacteria use the chaperone–usher (CU) secretion pathway to assemble on their surfaces typical or atypical fimbrial organelles. Four consecutive genes of Myxococcus xanthus DK1622, MXAN3885–3882, were predicted to constitute an operon encoding a CU ...

Induction and Enhancement of Bacteriocin Production (Review)

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

Bioremediation and Recovery of Lead and Cadmium by Spores of Bacillus subtilis C1

MicrobiologyOpen
Spores of a hot spring isolated strain of Bacillus subtilis were tested as a biotechnological tool to be used for the detoxification and bioremedition of heavy metals. Lead and cadmium were efficiently adsorbed by B. subtilis spores with those of C1 more

Assembly of multiple CotC forms into the Bacillus subtilis spore coat.

, 2004
We report evidence that the CotC polypeptide, a previously identified component of the Bacillus subtilis spore coat, is assembled into at least four distinct forms.

A protein phosphorylation module patterns the Bacillus subtilis spore outer coat

, 2020
Assembly of the Bacillus subtilis spore coat involves over 80 proteins which self-organize into a basal layer, a lamellar inner coat, a striated electrodense outer coat and a more external crust. CotB is an abundant component of the outer coat.

From pathogen to “living drug factory” innovative strategies and clinical translation of bacteria as programmable intelligent vectors for cancer therapy

BMEMat, EarlyView.
Engineered bacteria serve as smart, living therapeutics that target tumors, deliver drugs, and remodel immunosuppressive microenvironments. This review highlights their potential to potentiate immunotherapy, radiotherapy, and chemotherapy, offering a promising paradigm for precise and synergistic cancer treatment. Abstract The dynamic interplay between

A versatile class of cell surface directional motors gives rise to gliding motility and sporulation in Myxococcus xanthus.

PLoS Biology, 2013
Eukaryotic cells utilize an arsenal of processive transport systems to deliver macromolecules to specific subcellular sites. In prokaryotes, such transport mechanisms have only been shown to mediate gliding motility, a form of microbial surface ...

The spore coat of the bean anthracnose fungus Colletotrichum lindemuthianum is required for adhesion, appressorium development and pathogenicity [PDF]

, 2007
The spores (conidia) of the bean anthracnose fungal pathogen, Colletotrichum lindemuthianum, adhere to the aerial parts of plants to initiate the infection process.
