Dart frogs housed in a heavily planted bioactive display terrarium. A bioactive terrarium (or vivarium) is a terrarium for housing one or more terrestrial animal species that includes live plants and populations of small invertebrates and microorganisms to consume and break down the waste products of the primary species.
The most commonly used substrates are common soil, small pebbles, sand, peat, chips of various trees, wood mulch, vegetable fibres (of coconut, for example), or a combination of these. The choice of the substrate depends on the needs of the plants or of the animals, moisture, the risks involved and aesthetic aspects.
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.A substrate can include biotic or abiotic materials and animals. For example, encrusting algae that lives on a rock (its substrate) can be itself a substrate for an animal that lives on top of the algae.
Substrate is also useful for burrowing species as they can dig into the substrate as they would in their natural habitat. It is also useful for egg laying species that would naturally bury their eggs in the earth floor. The substrate also adds to the aesthetics of the enclosure and gives the vivarium a more natural feel and look. [1]
Juglone is an example of such a molecule inhibiting the growth of other plant species around walnut trees. [ citation needed ] The aquatic vascular plant Myriophyllum spicatum produces ellagic , gallic and pyrogallic acids and (+)- catechin , allelopathic phenolic compounds inhibiting the growth of blue-green alga Microcystis aeruginosa .
Bioactive glasses have been synthesized through methods such as conventional melting, quenching, the sol–gel process, flame synthesis, and microwave irradiation.The synthesis of bioglass has been reviewed by various groups, with sol-gel synthesis being one of the most frequently used methods for producing bioglass composites, particularly for tissue engineering applications.
Since these plants are also used for food products, diverting them for ethanol production can cause food prices to rise; cellulose-based sources, on the other hand, generally do not compete with food, since the fibrous parts of plants are mostly inedible to humans.
The flavin-containing monooxygenase (FMO) protein family specializes in the oxidation of xeno-substrates in order to facilitate the excretion of these compounds from living organisms. [1] These enzymes can oxidize a wide array of heteroatoms , particularly soft nucleophiles , such as amines , sulfides , and phosphites .
