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 first bioactive glass, developed by Larry Hench in 1969, was produced by melting a mixture of related oxide precursors at relatively high temperatures. This original bioactive glass, named Bioglass, was melt-derived with a composition of 46.1 mol% SiO 2, 24.4 mol% Na 2 O, 26.9 mol% CaO, and 2.6 mol% P 2 O 5. The selection of glass ...
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.
A greenhouse is an enclosure for plants with a glazed roof and wall(s) that allow the plants to make use of natural sunlight. A conservatory is a room of a house or of another building, with a glazed roof and wall(s) that combines growing space for plants with a sitting room or dining area for people. Some conservatories also house animals such ...
The construction of closed photobioreactors avoids system-related water losses and minimises contamination. [4] Though closed systems have better productivity compared to open systems due to this, they still need to be improved to make them suitable for production of low price commodities as cell density remains low due to several limiting factors. [5]
In actuality, however, plants do not absorb all incoming sunlight (due to reflection, respiration requirements of photosynthesis and the need for optimal solar radiation levels) and do not convert all harvested energy into biomass, which results in a maximum overall photosynthetic efficiency of 3 to 6% of total solar radiation. [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 .
The Institute for Local Self-Reliance estimates the cost of cellulosic ethanol from the first generation of commercial plants will be in the $1.90–$2.25 per gallon range, excluding incentives. This compares to the current cost of $1.20–$1.50 per gallon for ethanol from corn and the current retail price of over $4.00 per gallon for regular ...
