Embryo formation on callus tissues derived from zygotic or somatic embryos, seedling plant or other tissues in culture.
Industry:Biotechnology
Embryoids form directly in culture, without an intervening callus phase, on the surface of zygotic or somatic embryos or on explant tissues (leaf section, root tip, etc.).
Industry:Biotechnology
Embryos are produced either from somatic cells of explants (direct embryogenesis) or by induction on callus formed by explants (indirect embryogenesis).
Industry:Biotechnology
Encapsulated or coated somatic embryos (embryoids) that are planted and treated like seed.
Industry:Biotechnology
Entrapment of animal cells in some solid material in order to produce some natural product or genetically engineered protein. Animal cells have the advantage that they already produce many proteins of pharmacological interest, and that genetically engineered proteins are produced by them with the post-translation modifications normal to animals. However, because animal cells are much more fragile than bacterial ones, they cannot tolerate a commercial fermentation process. Typical materials are hollow fibre membrane bioreactors, or porous carriers made of polysaccharide, protein, plastic or ceramic materials with microscopic holes inside which the cells grow.
Industry:Biotechnology
Entrapment of plant cells in gel matrices; the cells are suspended in small drops of the material, which then is set or allowed to harden to make little carriers. Materials such as alginates, agar or polyacrylamide can be used.
Industry:Biotechnology
Enzymatic digestion (often by -amylase) of gelatinized starch to form lower molecular weight polysaccharides.
Industry:Biotechnology
Enzyme that attaches each amino acid to its specific tRNA molecule.
Industry:Biotechnology
Enzyme that catalyses the addition of adenine residues to the 3´ end of pre-mRNAs to form the poly-(A) tail.
