Responses to Heat and Cold Stress

14.0K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Diversity of Archaea IV

190
Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

6.8K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Physical Methods for Controlling Microbial Growth: Temperature

528
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

Effects of Temperature on Free Energy02:11

Effects of Temperature on Free Energy

26.4K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Area of Science:

  • Environmental Chemistry
  • Soil Science
  • Geochemistry

Background:

  • Dissolved organic matter (DOM) is crucial for heavy metal mobility in soils.
  • Soil temperature significantly influences DOM characteristics and heavy metal interactions.
  • Understanding these interactions is vital for predicting heavy metal fate under climate change.

Purpose of the Study:

  • To investigate the effect of elevated temperatures on soil DOM composition and structure.
  • To determine how temperature-induced DOM changes affect the binding of cadmium (Cd) with DOM.
  • To elucidate the binding sequence and intensity of Cd with different DOM fractions at varying temperatures.

Main Methods:

  • A 180-day soil incubation experiment was conducted at 15°C, 30°C, and 45°C.
  • Fluorescence spectroscopy analyzed DOM composition.
  • Two-dimensional correlation spectroscopy assessed Cd-DOM binding dynamics.

Main Results:

  • Temperature changes affected DOM humification and aromaticity, with a peak at 30°C.
  • Cd binding to DOM functional groups was not altered in type, but the binding sequence shifted with temperature.
  • Polysaccharide, phenolic, and aromatic groups showed the fastest response to Cd at 15°C, 30°C, and 45°C, respectively.

Conclusions:

  • Soil temperature significantly alters the binding sequence of cadmium with dissolved organic matter fractions.
  • These findings enhance understanding of cadmium's environmental behavior in arable soils under warming conditions.
  • The study highlights the complex interplay between temperature, DOM properties, and heavy metal fate.
