bioavailability
(noun)
The amount of matter that is physicochemically accesible for degradation by microorganisms.
Examples of bioavailability in the following topics:
-
Modeling Ecosystem Dynamics
- To model the cycling of mineral nutrients, organic and inorganic nutrients are subdivided into those that are bioavailable (ready to be incorporated into biological macromolecules) and those that are not.
-
The Degradation of Synthetic Chemicals in Soils and Water
- The limiting factor for bioremediaton in soils is the bioavailability of the contaminant agents.
-
Hair and Hormones
- Sex hormone-binding globulin (SHBG), which is responsible for binding testosterone and preventing its bioavailability and conversion to DHT, is typically lower in individuals with high DHT.
-
Siderophores
- However, despite being one of the most abundant elements in the Earth's crust, the bioavailability of iron in many environments such as the soil or sea is limited by the very low solubility of the Fe3+ ion.
-
Polycyclic Aromatic Hydrocarbons
- Bioremediation can occur on its own (natural attenuation or intrinsic bioremediation) or can be spurred on via the addition of fertilizers to increase the bioavailability within the medium (biostimulation).
