| environ. | mutated micro-organisms release | liberación transformada de microorganismos |
| environ. | mutated micro-organisms release The release of mutated micro-organisms creates the risk that they may exhibit some previously unknown pathogenicity, might take over from some naturally occurring bacteria (possibly having other positive functions which thus are lost) or pass on some unwanted trait to such indigenous bacteria. There is also concern that an uncontrolled genetic mutation could produce from such an engineered microorganism, a form with hazardous consequences for the environment | liberación transformada de microorganismos |
