Veins as Blood Reservoirs01:10

Veins as Blood Reservoirs

7.6K
Veins, while chiefly responsible for circulating blood back to the heart, also function as storage vessels for blood. They house approximately 64 percent of the body's total blood volume, a feat made possible by their high capacitance—the inherent ability to expand and accommodate large volumes of blood, even under low pressure. The large diameter and thin walls of veins augment their distensibility, significantly more so than arteries, due to their classification as capacitance...

Dynamic Equilibrium02:20

Dynamic Equilibrium

62.0K
A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When the rates of the forward and reverse reactions are equal, the concentrations of the reactant and product species remain constant over time and the system is at equilibrium. A special double arrow is used to emphasize the reversible nature of the reaction. The relative concentrations of reactants and products in equilibrium systems vary greatly;...

Functional Groups

87.9K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Equation of Rotational Dynamics01:08

Equation of Rotational Dynamics

14.7K
Angular variables are introduced in rotational dynamics. Comparing the definitions of angular variables with the definitions of linear kinematic variables, it is seen that there is a mapping of the linear variables to the rotational ones. Linear displacement, velocity, and acceleration have their equivalents in rotational motion, which are angular displacement, angular velocity, and angular acceleration. Similar to the rotational variables, a mapping exists from Newton's second law of motion...

Fermi Level Dynamics01:12

Fermi Level Dynamics

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Area of Science:

  • Environmental microbiology
  • Bioremediation
  • Halogen cycling

Background:

  • Organohalide-respiring bacteria (OHRB) are vital for halogen cycling and pollutant degradation but face challenges like slow growth.
  • Dehalococcoides, a key OHRB, exhibits declining abundance and gene loss in bioaugmentation, impacting functional stability.
  • Mechanisms supporting long-term OHRB functional stability are not fully understood.

Purpose of the Study:

  • To investigate the role of strain-level microdiversity in Dehalococcoides for community-scale dehalogenation resilience.
  • To understand how genetic variation within Dehalococcoides populations contributes to functional stability under cultivation.

Main Methods:

  • Reconstruction of a Dehalococcoides consortium (AEDhc) from eight enrichment cultures.
  • Sequencing of a Dehalococcoides-specific marker gene to identify coexisting phylotypes.
  • Proteomics analysis to identify expressed reductive dehalogenase (RDase) genes.

Main Results:

  • AEDhc harbored 30 distinct Dehalococcoides phylotypes.
  • The consortium consistently debrominated tetra- and pentabrominated diphenyl ethers without intermediate accumulation.
  • Expression of RDase genes was dominated by PcbA1-like and TceA-like RDases across transfers, despite phylotype abundance fluctuations.

Conclusions:

  • Coexistence and dynamic fluctuations of Dehalococcoides phylotypes enhance functional stability and ecological resilience.
  • Genetic variation within Dehalococcoides serves as a reservoir of metabolic potential for sustained dehalogenation.
  • Strain-level heterogeneity is critical for effective bioremediation strategies using OHRB.
