Containment biological

Biological coiitainment involves the nse of cells, vectors, genes, and APIs wliich, upon release from the targeted or optimal eiivironment, will not interact with the biological systems they enconnter. This means tliat high-perforniance strains are auxotrophic for rare 

Physical/chemical containment takes into account the toxicity, viralence, and potential for change and evolution of biological agents, and uses baixiers, closed systems, and physical deshuction by madiation, chemicals and tempeiatm e to prevent the escape of viable agents.

Many molecules of interest to chemistry and biology contain H atoms. For the unimolecular dissociation of the excited states of such molecules, it is instructive to think of elimination of a particle or a group of particles. Thus, we can think of elimination of an electron, an H atom, an H2 molecule, an alkane group (in suitable cases), and so forth. Other factors remaining the same, the rate of the process may... 

The Sunshine Project (http //www hammond sunshine-project.org P.O. Box 41987, Austin, Texas 78704) keeps track of biological containment labs in the United States. This group published a listing of High Containment Labs and Other Facilities of the US Biodefense Program in November of 2004 (biological containment labs 3 and 4 not known to be heavily dedicated to bio-defense are not indicated on the listing).

The lack of human pathogenicity of plant viruses rules out the risks of human infection by exposure in the field or in food products to a plant virus. However, biological containment of the virus expression vector remains a primary safety concern as it can be considered a risk to the environment. This includes the spread of recombinant viruses to weeds...

Having defined four levels of physical containment and three levels of biological containment, the Guidelines then went on to specify levels of physical and biological containment required for each of many different kinds of experiments. There were specific sections dealing with the use of plant DNA and plant viral DNA inserted into E. coli K-12, and the insertion of foreign DNA into plants, plant parts, seedlings or plant cells in tissue culture, all to be contained within the research laboratory.
