This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. Cryopreservation is also used for the conservation of livestock genetics through cryoconservation of animal genetic resources .
Bioremediation techniques can be classified as (i) in situ techniques, which treat polluted sites directly, vs (ii) ex situ techniques which are applied to excavated materials. [8] In both these approaches, additional nutrients, vitamins, minerals, and pH buffers are added to enhance the growth and metabolism of the microorganisms.
Remediation technologies are many and varied but can generally be categorized into ex-situ and in-situ methods. Ex-situ methods involve excavation of affected soils and subsequent treatment at the surface as well as extraction of contaminated groundwater and treatment at the surface. In-situ methods seek to treat the contamination without ...
Ex situ conservation is defined as the “conservation of components of biological diversity outside their natural habitats.” [50] Ex situ conservation is the conservation of genetic resources (species, varieties, cultivars, sub-species, landraces etc.) for food and agriculture outside their natural habitat, in a managed environment including ...
This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. However, cryo-conservation can be an expensive strategy and requires long term hygienic and economic commitment for germplasms to remain viable.
In-situ conservation of seed-producing plant species is another conservation strategy. In-situ conservation involves the creation of National Parks, National Forests, and National Wildlife Refuges as a way of preserving the natural habitat of the targeted seed-producing organisms. In-situ conservation of agricultural resources is performed on-farm.
It involves the application of science and technology in the process of addressing environmental challenges through environmental conservation and the mitigation of human impact to the environment. The term is sometimes also used to describe sustainable energy generation technologies such as photovoltaics , wind turbines , etc. [ citation needed ]
Nevertheless, in many cases research is focused on the extraction of soil and water and its ex situ biological treatment to avoid these problems. [4] Finally, the potential of GMOs is limited by regulatory agencies in terms of responsibility and bioethical issues. Their release require support on the action zone and comparability with ...
