Factors contributing to helical shape determination and maintenance in Bacillus subtilis macrofibres

Annales de l'Institut Pasteur / Microbiologie, 1985
Bacillus subtilis, normally a rod-shaped organism, can grow in the form of a helix with pitch ranging over a spectrum from tight right-handed to tight left-handed depending upon the growth environment and genetic composition of the strain. Five factors have been identified which contribute either to the helical shape deformation or its maintenance: 1 ...

Self-Assembly of Magnetic Bacillus-Shaped Bilayer Vesicles in Catanionic Surfactant Solutions

Langmuir, 2016
Bacillus-shaped bilayer vesicles of nanoscale size are very rare structures of stable surfactant self-assembly, because they are both thermodynamically and electrostatically unfavorable in solution. It is evidently demonstrated that appropriately aqueous mixtures of single-tailed cationic and anionic (catanionic) surfactants can produce rigidly ...

Biosynthesized silver nanoparticles using Bacillus amyloliquefaciens; Application for cytotoxicity effect on A549 cell line and photocatalytic degradation of p-nitrophenol.

Journal of Photochemistry and Photobiology. B: Biology, 2019
The present study reports the biosynthesis of silver nanoparticles (AgNPs) using Bacillus amyloliquefaciens MSR5. The cellfree supernatant of B. amyloliquefaciens acted as a stabilizing agent for the synthesis of AgNPs.

Bacillus quorum quenching shapes the citrus mycobiome through interkingdom signaling

Science of The Total Environment
Microbiomes are sustained through infinite yet mutually interacting microbial communities, with bacteria and fungi serving as the major constituents. In recent times, microbial interventions have become popular for microbiome manipulation to achieve sustainable goals.

Environment Shapes the Intra-species Diversity of Bacillus subtilis Isolates

Microbial Ecology, 2019
Cosmopolitan bacteria are those that are found practically everywhere in the world. One of them is Bacillus subtilis, which can travel around the world through dust storms rising from various deserts. Upon landing, bacterial survival is determined by the ability to adjust to the heterogonous environments and bacteria isolated from extremely different ...

Coccus-shaped Bacillus subtilis cells are inhibited at stage 0 of sporulation

Canadian Journal of Microbiology, 1988
RodA and rodB mutations cause rod-shaped Bacillus subtilis cells to become coccus-shaped when the growth temperature is increased from 30 to 45 °C. At 30 °C four rod strains sporulated as well as the genetically closely related rod+ strains. In contrast, at 45 °C the sporulation frequencies of rod strains decreased approximately 102- to 104-fold ...

Extracellular synthesis of nanoselenium from fresh water bacteria Bacillus sp., and its validation of antibacterial and cytotoxic potential

, 2020
In this present study, selenium reducing bacteria were isolated from fresh water pond. The cell free supernatant from B2 strain was found to effectively reduce sodium selenite and was identified as Bacillus sp. Based on 16S r RNA sequencing. The selenium
