  • 1995. Bacterial community structures of phosphate-removing and non-phosphate-removing activated sludges from sequencing batch reactors. (asmscience.org)
  • dormant
  • Bacterial spores are the most resistant and dormant forms of life on earth. (wiley.com)
  • Research that spans many years has revealed that endospore formation is a complex and elegant process that exquisitely coordinates the development of a dormant spore. (caister.com)
  • Furthermore, the fact that the enzymes are heat sensitive only when removed from intact spores indicate the presence of some heat protective mechanism for enzymes in rather peripheral location in the dormant spore, which is not dependent on the core environment of spores. (nii.ac.jp)
  • Bacterial spores are highly resistant, dormant structures (i.e. no metabolic activity) formed in response to adverse environmental conditions. (microbeonline.com)
  • Bacterial spores, when found in the environment, are often considered to be dormant and metabolically inactive, in a resting state waiting for favorable conditions for them to germinate. (asmscience.org)
  • sporulation
  • We discuss the developmental process that yields M. xanthus spores, the structural and biochemical properties of the spores and the genes that are associated with sporulation in this organism, and we compare each to its counterpart in Bacillus . (caister.com)
  • Here, we discuss the classical studies that established a solid genetic understanding of aerial development and sporulation, and highlight important new advances in the areas of cell division and spore septum placement, chromosome segregation and condensation during sporulation, and spore maturation. (caister.com)
  • Spore formation (sporulation) occurs when nutrients, such as sources of carbon and nitrogen are depleted. (microbeonline.com)
  • antibody
  • The spore appears to present a bound antigen in its native conformation promoting a cellular (T(h)1-biased) response coupled with a strong antibody response. (ei-resource.org)
  • Spores of Bacillus subtilis (Bacillus anthracis simulant) were immobilized on a thickness-shear mode AT-cut quartz crystal functionalized with anti-spore antibody and the sensor was driven by a pure sinusoidal oscillation at increasing amplitude. (cam.ac.uk)
  • botulism
  • Most cases of infant botulism, however, are thought to be caused by acquiring the spores from the natural environment. (wikipedia.org)
  • Radiation
  • Astrophysicist Steinn Sigurdsson said "There are viable bacterial spores that have been found that are 40 million years old on Earth - and we know they're very hardened to radiation. (wikipedia.org)
  • surfaces
  • Surfaces may become contaminated with the spores with further spread occurring via the hands of healthcare workers. (wikipedia.org)
  • heat
  • Of these, the use of genetically engineered bacterial spores has been shown to offer promise as both a mucosal as well as a heat-stable vaccine delivery system. (ei-resource.org)
  • surface
  • In this work we have discovered that the negatively charged and hydrophobic surface layer of spores provides a suitable platform for adsorption of protein antigens. (ei-resource.org)
  • Biomolecular interaction forces between the coupled spores and the accelerating surface caused a nonlinear modulation of the acoustic response of the crystal. (cam.ac.uk)
