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.

• Plant Adaptations to Life on Land

  • Desiccation, or drying out, is a constant danger for organisms exposed to air.
  • Even when parts of a plant are close to a source of water, the aerial structures are prone to desiccation.
  • As such, both gametes and zygotes must be protected from desiccation.
  • One of these strategies is called desiccation tolerance.
  • The vulnerable embryo must be sheltered from desiccation and other environmental hazards.

• The Evolution of Seed Plants and Adaptations for Land

  • Several layers of hardened tissue prevent desiccation, freeing reproduction from the need for a constant supply of water.
  • Furthermore, seeds remain in a state of dormancy induced by desiccation and the hormone abscisic acid until conditions for growth become favorable.
  • The whole structure is protected from desiccation and can reach the female organs without dependence on water.

• 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.

• Bryophytes

  • They constitute the major flora of inhospitable environments like the tundra where their small size and tolerance to desiccation offer distinct advantages.

• Zygomycota: The Conjugated Fungi

  • The developing diploid zygospores have thick coats that protect them from desiccation and other hazards.

• Characteristics of Epithelial Tissue

  • Protection for the underlying tissues from radiation, desiccation, toxins, and physical trauma.

• 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.

• Physical and Chemical Barriers

  • Pathogens are killed or inactivated on the skin by desiccation (drying out) and by the skin's acidity.

• 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.
