desiccation

Examples of desiccation in the following topics:

• Desiccation

  • Desiccation is the state of extreme dryness, or the process of extreme drying and can be used to control microbial growth.
  • Desiccation is the state of extreme dryness, or the process of extreme drying.
  • In biology and ecology, desiccation refers to the drying out of a living organism.
  • After the addition of water, the bacteria will start growing again, so desiccation does not provide complete sterilization.
  • Some bacteria, such as Deinococcus radiodurans and Mycobacterium, are extremely resistant to damage from prolonged desiccation while others, such as Neisseria gonorrhoeae, can survive only short periods of desiccation.

• Glycocalyx

  • Capsules also contain water which protects bacteria against desiccation.
  • The function of the slime layer is to protect the bacteria cells from environmental dangers such as antibiotics and desiccation.

• Firmicutes

  • Many Firmicutes produce endospores, which are resistant to desiccation and can survive extreme conditions.
  • They can survive without nutrients and are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants.

• Extremely Halophilic Archaea

  • Most halophilic organisms cope with the high concentrations of salt by expending energy to exclude salt from their cytoplasm to avoid protein aggregation, or "salting out. " "Normal" organisms would desiccate in these conditions, losing water via osmosis out of the cytoplasm.

• Sporulation in Bacillus

  • B. subtilis can divide symmetrically to make two daughter cells (binary fission), or asymmetrically, producing a single endospore that is resistant to environmental factors such as heat, desiccation, radiation, and chemical insult which can persist in the environment for long periods of time.

• Endospores

  • They are resistant to ultraviolet radiation, desiccation, high temperature, extreme freezing and chemical disinfectants.

• Deinococcus and Thermus

  • It is extremely resistant to ionizing radiation, ultraviolet light, desiccation, and oxidizing and electrophilic agents.

• Non-Spore-Forming Firmicutes

  • Many Firmicutes produce endospores, which are resistant to desiccation and can survive extreme conditions.

• Nongenetic Categories for Medicine and Ecology

  • Xerophile: an organism that can grow in extremely dry, desiccating conditions; exemplified by the soil microbes of the Atacama Desert
